Coordination

As far as repeated words are concerned, they are normally written separately (with a comma),^[19] but a hyphen is used if their connection is more than occasional (e.g. ki 'who' but ki-ki 'everyone').^[20] If a word is repeated with a different suffix or postposition, the words are written separately (napról napra 'day by day', lit. 'from day to day'), except if an element only exists in this phrase, in which case the words are written with a hyphen (régi 'old' réges-régi 'ancient old').^[21]

Coordinated words are normally written separately (with a comma).^[22] If the meaning of the result is different from that of the two words together, but both elements take suffixes, they are written with a hyphen (e.g. süt-főz 'cook', consisting of words referring to cooking in the oven and cooking in water, sütnek-főznek 'they cook'). A hyphen is needed in cases when a phrase is only used with certain suffixes.^[23] Connections of words which are completely fused and thus take suffixes only at the end of the second element are written as one word (e.g. búbánat 'sorrow and grief', búbánatos 'stricken with sorrow and grief').^[24] However, there are phrases that only take suffixes at the end but their elements are still connected with a hyphen, as when words are contrasted (e.g. édes-bús 'bittersweet').^[25] Certain phrases can be suffixed either at the end of both elements or only at the end of the second element (e.g. hírnév 'fame': hírneve or híre-neve 'his/her/its fame').^[26]

Subordination

As shown by printed material and street inscriptions, this field is probably the most problematic for the majority of native speakers even at a reasonably educated level. The main principle is that these compounds have to be written without spaces if any of these three criteria are met:^[27]

1. there is a change of meaning, which cannot be deduced from the elements alone,
2. an inflectional suffix is omitted,
3. tradition (the examples in this group are limited, though).

This applies to phrases and compounds of many types, like those where the first element is the subject of the second (which is a participle),^[28] or it is the adjective^[29] of the second (e.g. gyors vonat means 'fast train', while gyorsvonat means 'express train' as a type of train: the change in meaning makes it necessary to write the latter as one word).

Problematic point(s): it is virtually unpredictable whether the change in meaning (as compared to the mere sum of its elements) is attributed to one element or the whole compound. For example, élő adás 'live programme' is written as two words, even though the word élő is used differently from its basic meaning – probably because it was decided that this component can carry the change of meaning, so writing the compound as one word is not necessary. On the other hand, gyorsétterem 'fast food restaurant' (lit. 'fast restaurant') is written as one word – probably because the change of meaning was attributed to the whole compound, leaving the lexical meaning of the word gyors intact. Some phrases without any change of meaning are written as one word, e.g. útitárs 'travel companion', while most other phrases are written regularly: úti cél 'travel destination.'

Sometimes the original meaning of the adjective is retained, but the whole compound still means something more specific than the sum of the elements. For example, savanyú káposzta, lit. 'sour cabbage', actually 'sauerkraut', is more than a cabbage that tastes sour: it means a type of pickled food, yet it is written with a space. On the other hand, mobiltelefon 'mobile phone' is written in one word, although it is actually a telephone that is mobile – writing in one word may be justified by the different technology, as distinguished from a cordless telephone, which is also portable.

As far as the suffix omission is concerned, often there is a grammatical relationship between two nouns of a compound which could also be expressed in a marked, more explicit way: for example ablaküveg 'window pane' could be expressed as az ablak üvege 'the pane of the window,' and based on this derivation, it needs to be written as one word. The word bolondokháza 'confusion, turmoil' also needs to be written as one word, despite the marked possessive, so as to avoid the literal meaning 'house of fools' (1st case). Other compounds, where the first element gives the object,^[30] the adverb,^[31] or the possessor,^[32] are also written in one word where the suffix is omitted, or if the actual meaning is different from the sum of its elements. Thus, szélvédett 'wind-protected' can be deduced from széltől védett 'protected from [the] wind', and it is written together as the suffix től is omitted.^[33] Verbal phrases where the suffix is marked are usually written in two words, even if the meaning has become figurative, (e.g. részt vesz 'take part'),^[34] while other phrases with a marked suffix are written in one word (e.g. észrevesz 'notice, spot', literally "take on the mind").^[35]

Problematic point(s): there are more than a hundred verbal phrases^[36] that are used exactly like verbs with a verbal prefix (cf. "eat up" in English), like részt vesz above, but they must be written as two words.

Verbal prefixes (cf. Vorsilben in German) are only written together with the verb they belong to if they immediately precede that verb. If the same verbal prefix is repeated to express repeated action, the first is divided by a hyphen, the second is written in one word (meg-megáll 'keep stopping once in a while'). If two verbal prefixes with an opposite meaning follow each other, both are written separately (le-föl sétál 'walk up and down'). Verbal prefixes may be written separately if the meaning of the prefix is stressed and the prefix is meant in a literal sense, but they must be written as one word if the meaning is changed (e.g. fenn marad 'stay upstairs' but fennmarad 'survive, remain'). Some verbal prefixes coincide with adverbs that can have personal endings. In this case, they can only be written as one word if they are in the third person plural and the prefix/adverb is not stressed on its own (especially if the meaning is changed). Otherwise (if another person is used and/or the prefix/adverb is stressed) they should be written in two words.^[37]

Problematic point(s): phonologically speaking, verbal prefixes are always attached to the following verb, even if it is an auxiliary verb wedged in between, which loses its own stress. For example: megfog means 'catch' and megnéz means 'see, have a look.' Thus, megfogom a lepkét 'I'll catch the butterfly' but meg fogom nézni 'I'm going to see it.' In the first example, meg belongs to fogom; in the second, meg belongs to nézni. The pronunciation is ['megfogom] in both cases. These cases can be distinguished, though, by considering the word elements. On the other hand, verbal prefixes with personal suffixes can never be written together with the main verb, even though they are stressed the same way as unsuffixed prefixes, e.g. rám néz, rád néz but ránéz 's/he looks at me, you, him/her.'

A separate group of compounds with subordinated elements is the one named literally "meaning-condensing" or "meaning-compressing" compounds, which have a more complex internal structure, containing implicit elements outside the constituting words, or sometimes where the present meaning cannot be derived at all from the elements. They are always written in one word, e.g. csigalépcső 'spiral staircase,' lit. "snail-staircase", i.e. a staircase similar to the shell of snails.^[38]

If a phrase (e.g. an adjective and a noun or a noun and a postposition) written in two words receives a derivational suffix, it will also be written in two words – except if the meaning is changed.^[39] However, if they receive a second derivational suffix, the phrase will be written in one word.^[40] (For example: egymás után 'one after the other', egymás utáni 'successive', but egymásutániság 'successiveness,' i.e. 'succession.' In addition: föld alatt 'under the ground', föld alatti 'being under the ground' but földalatti 'underground <movement>' or 'subway, tube.')

Problematic point(s): there are more than fifty phrases written in one word only after one single derivational suffix (e.g. partra száll 'disembark' but partraszállás 'disembarkation').^[41]

Appositional compounds are normally written in two words, e.g. 'a footballer wife' (a wife who plays football) is expressed as futballista feleség. However, if there is a possessive relationship between the words, i.e. if the wife of a footballer is meant, it is considered a (regular) compound, thus it should be written as one word: futballistafeleség.^[42] There are several appositional compounds though, which are written as one word, especially where the first element specifies the type of the second (e.g. diáklány 'student girl').^[43]

Problematic point(s): people find long words difficult to read, so many still prefer to write them separately, relying on the context to clarify the meaning. In addition, the justification for the above subtype that provides specification is considered vague.

Phrases whose first element is a participle are written separately if the participle expresses an occasional action: dolgozó nő 'a working woman, a woman at work.' However, if the participle expresses function, purpose, ability, task, or duty, the phrase is considered a compound and is written as one word, e.g. mosónő 'washerwoman', someone whose duty is to wash. Sétálóutca 'walking [pedestrian] street' means a street for walking: writing as one word expresses that it is not the street that walks.

Problematic point(s): there are several received expressions referring to function that are written separately despite the above rules (e.g. kijelentő mód 'indicative mood' lit. 'declaring mood', even though the mood is used for declarations, it doesn't declare anything), so it is sometimes not obvious how a newly coined construction should be written. In addition, present participles sometimes become nouns, and their compounds cannot be written in two words, as they cannot be considered adjectives anymore. For example, labdarúgó 'footballer' was created from a participle (lit. 'ball-kicking' [person]) but it is a noun today, and since labdarúgómez 'footballer's strip' implies a possessive relationship, it must be written in one word.

Hyphenating long compounds

Proper names

The following type of proper names are distinguished: personal names, animals' names, geographical names, astronomical names, names of institutions, brand names, names of awards and prizes, and titles (of works).

Proper names may become common names, and in this case they are written in lowercase (e.g. röntgen 'x-ray') and even their derived compounds may become lowercase, losing the hyphen (e.g. ádámcsutka rather than *Ádám-csutka 'Adam's apple').^[55]

Geographical names

The two most important questions about geographical names are whether a name should be written in one word, with a hyphen, or in separate words, and which elements should be written uppercase and lowercase. Different written forms may refer to different entities, e.g. Sáros-patak lit. 'muddy river' refers to a river, but Sárospatak refers to a city (because rivers' names are written with a hyphen, but city names are written as one word). This field is considered one of the most complex parts of Hungarian orthography, so a separate volume has been published about it,^[68] and a separate board (Földrajzinév-bizottság)^[69] working in the Ministry of Agriculture is entitled to give statements. It consists of experts in linguistics, education, transportation, hydrology, natural protection, public administration, ethnic minorities, foreign relations, and other fields.

Apart from single-element names, country names with -ország, -föld, -alföld or -part ('country', 'land', 'plain', 'coast') and most regions are written in one word, as well as Hungarian settlements and their districts ("towns") and quarters, and even Hungarian names outside Hungary. The adjective-forming suffix -i (sometimes -beli) is attached directly to the name. If it already ends in -i, this ending is not repeated.^[70]

Problematic point(s): certain region names have become one word, dropping the hyphen, such as Dunakanyar; there are about 60 such forms.^[71] Quarters also need to be written as one word, even if they contain a proper name (e.g. Wekerletelep, lit. "Wekerle's settlement"), and even if they exceed the 6 syllables (e.g. Szépkenyerűszentmárton, 7 syllables and 4 elements, despite the above-mentioned syllable-counting rule).^[72]

If a geographical name contains a common geographical expression (river, lake, mountain, island etc.) or another common noun or an adjective, the compound is written with a hyphen (e.g. Huron-tó 'Lake Huron' or Új-Zéland 'New Zealand'). When these forms are converted into an adjective, only those elements are left capitalized which are actual proper names themselves (Kaszpi-tenger and Kaszpi-tengeri 'Caspian Sea', however Új-Zéland and új-zélandi – zélandi is not considered a proper name because it carries the adjectival suffix).^[73] The same rule is applied to compounds with three or more elements, although compounds with more than four elements are simplified (lower-ranked hyphens are removed).^[74]

An en dash is used to express a relation between two places, and its adjectival form becomes completely lower-case (e.g. Moszkva–Párizs 'Moscow-Paris [route]' and moszkva–párizsi 'of the Moscow-Paris route'). However, if a higher-ranked connected element becomes an adjective, the geographical proper names will retain the upper case (e.g. Volga–Don-csatorna 'Volga-Don canal' vs. Volga–Don-csatornai), except when the elements of the name contain adjectives or common nouns, which will become lower-case (e.g. Cseh–Morva-dombság 'Bohemian-Moravian Highlands' vs. cseh–morva-dombsági).^[75]

All elements are written separately (excluding the above-mentioned names that are written as one word or with a hyphen) in current and historical country names and geographical-historical region names. Their adjectival forms are all written with lower case. (For example, Egyesült Királyság 'United Kingdom' vs. egyesült királysági 'from/of the U.K.', Dél-afrikai Köztársaság 'South African Republic' vs. dél-afrikai köztársasági but San Marino Köztársaság 'Republic of San Marino' vs. San Marino köztársasági).^[76]

Only the first element is capitalized in subnational entities like counties, areas, districts, neighbourhoods. When forming an adjective, this uppercase letter is only kept if this element is a proper name, e.g. New York állam 'State of New York' vs. New York állami. However, if the first element of such an entity is a common noun or an adjectival form, all elements are written lower case (e.g. in names of local administrative units like Váci kistérség vs. váci kistérségi).^[77]

Names of public spaces (roads, streets, squares, bridges etc.) are written separately (except for elements that are already compounds or hyphenated). Their first element is capitalized, and this capitalization is kept even in the adjectival forms, e.g. Váci utca 'Váci Street' and Váci utcai.^[78]

Problematic point(s): people need to know if a phrase is officially the name of that place or just a designation, e.g. Erzsébet híd is a name ('Elisabeth Bridge') but Duna-híd merely refers to a bridge on the Danube, so a hyphen should be used.

If a common name is added to a geographical name to clarify its nature, it is written separately.^[79]

Problematic point(s): it is often unclear whether a common noun is actually part of an official geographical name, e.g. many people believe Fertő tó is the actual name of Fertő Lake so they write it with a hyphen; but the name is only Fertő, thus a space must be used before tó. In addition, names like Szahara sivatag ('Sahara Desert') or Urál hegység 'Ural Mountains' do not contain the common name, so no hyphen must be used, as opposed to the Kaszpi-tenger type.

If a geographical name consists of several elements whose relationship is marked by suffixes or postpositions, these elements are also written separately. The uppercase letter of the beginning element is kept even in an adjectival form.^[80]

Problematic point(s): the suffix that marks the possessive relationship is lost in the adjectival form, so the relationship is eventually unmarked, but the hyphen is still not used. For example, when Vác környéke 'Vác environs' becomes Vác környéki 'of/from Vác environs', the possessive-marker -e is lost, so it seemingly becomes analogous with the above Kaszpi-tengeri type. In addition, while names like Külső Pesti út ('Outer Pest Road') makes it obvious that külső is part of the name (rather than an occasional designation), the adjectival form Külső Pesti úti can only be given correctly with this knowledge.

The above case of Jeremiás próféta kolostor emerges again with the type of Mária asszony sziget 'Lady Mary Island', where sziget 'island' would normally be connected with a hyphen, were it not for the common noun asszony 'lady' in the original name, which makes it impossible, so all elements have to be written separately.^[80]

Stars and other astronomical objects

Stars, constellations, planets, moons are written with an uppercase capital, e.g. Föld 'Earth', Tejút 'Milky Way', especially as astronomical terms. In everyday usage, however, names of the Earth, the Moon, and the Sun are normally written in lowercase (föld körüli utazás 'a journey around the Earth').^[81]

Institutions

Names of offices, social organizations, educational institutions, academic institutes, cooperatives, companies etc. are written capitalizing all elements except conjunctions and articles. In adjectival forms, only actual proper names and trade names ("fantasy names") are left uppercase. For example, Országos Széchényi Könyvtár 'National Széchényi Library' vs. országos Széchényi könyvtári or Bíró Háza Étterem és Panzió "[The] Judge’s House Restaurant and Guesthouse" vs. Bíró Háza étterem és panzióbeli, retaining the capitalization of Bíró Háza "[the] Judge’s House" in the adjectival form.^[82]

Problematic point(s): it is not always known whether a specific form is actually the official name of an institution, or what is its official name (e.g. whether the city where it is located is part of the name). In addition, it is not always clear if a group is actually an institution in the sense of having been registered at the court, with a statute, a stamp, letter header etc. on its own. A third problem is the question of whether the spelling of an organization can be corrected if it is not written according to the above rule. In addition, adjectival forms derived from institution names are also often mistaken because people feel the need to distinguish them from genuine common nouns (especially if the name contains a trade name that becomes identical with a common noun if written in lowercase). Furthermore, it is unclear why cinemas are treated differently (see above) from theatres, cf. Művész mozi, but Magyar Színház.

If a part of the institution name stands for the whole name, its upper case form is preserved if it is a specific keyword of the name. However, if a common noun part is used for the whole name, it is written in lower case (except for Akadémia for the Hungarian Academy of Sciences and Opera for the Hungarian State Opera House).^[83]

This rule is commonly violated in legal documents where the authors want to make it as clear as possible that the names refer to the contracting parties in particular, so they write it in upper case (not only the common noun parts of the company names but also generic words referring to the parties involved).

Subordinated units of institutions are written in uppercase if they are major divisions (e.g. Földrajzi Társaság 'Geographical Society', under the Hungarian Academy of Sciences), not including the personnel department or the warden's office.^[84]

Railway stations, airports, cinemas, restaurants, cafés, shops, baths and spas, cemeteries etc. are considered less conventional institutions, so normally only their actual proper name elements (including possible trade names, "fantasy names") are written in upper case, apart from the first word. Their adjectival forms retain the original case. For example, Keleti pályaudvar 'Eastern Railway Station' vs. Keleti pályaudvari; Vén Diák eszpresszó 'Alumnus Café' (or 'Old Student Café') vs. Vén Diák eszpresszóbeli.^[85] However, most of these names may also be full institution names, thus their spelling reflecting the rules given above (see the beginning of this section).^[86]

Brand names

Names of products, articles, makes, and brands are written capitalized, e.g. Alfa Romeo. This does not include names which include the material or origin of the product, e.g. narancsital 'orange juice'. If the word showing the type is added to the name for clarification, it is done with a space, and in lowercase, e.g. Panangin tabletta 'Panangin pill'.^[87]

Awards and prizes

Words denoting a prize, an award, a medal etc. are attached with a hyphen to proper names, e.g. Kossuth-díj 'Kossuth Prize.' If the name consists of several elements, whose relation is marked, all the elements are capitalized, e.g. Akadémiai Aranyérem 'Golden Medal of the academy.' Degrees and types of awards are written in lowercase.^[88]

Titles of works

Titles are classified as constant and individual titles: the first being the title of newspapers, periodicals, magazines, and the second used with literary, artistic, musical, and other works, articles etc.^[89]

All elements of constant titles are written in uppercase (e.g. Élet és Tudomány 'Life and Science' [weekly]),^[90] while only the first word is capitalized in individual titles (e.g. Magyar értelmező kéziszótár 'Defining Desk Dictionary of the Hungarian Language' or Kis éji zene 'A Little Night Music').^[91]

Suffixes are attached to titles without a hyphen, except if a title already ends in a suffix or a punctuation mark, or if the suffix creates an adjective: in these cases, a hyphen must be used. (For example: a Magyar Hírlapban 'in Magyar Hírlap' but Magyar Hírlap-szerű 'Magyar Hírlap-like.')^[92]

Non-proper names

Names of national and religious holidays, celebrations, notable days, periods, historical events are not capitalized (nor day or month names), neither are names of nationalities and ethnicities, languages and language groups as well as religions.^[93] Events, programmes, and arrangements are not capitalized either,^[94] except if they have an institutional background.^[95]

Problematic point(s): an average person cannot always know if an event has an institutional background. Therefore, events are still usually written with capital letters.

Apart from personal names, commons nouns expressing rank or relation may also be capitalized in addresses for reasons of politeness.^[96] suffixes and titles like Doctor, Junior, Senior, and their abbreviations are only capitalized if they are in a prominent position (e.g. in postal addresses or lists).^[97]

Common nouns

If a word comes from a language using the Latin script, it is only respelled if it has become an integral, widely known part of Hungarian language (e.g. laser > lézer; manager > menedzser).^[98] If it is less widely used, it retains its original spelling, e.g. bestseller, myocarditis, rinascimento.^[99] But there is no hard and consistent rule, and many widely used terms are written in the original spelling, e.g. musical or show. Certain phrases from foreign languages are always written in their original form, even if the individual words would be respelled in isolation, e.g. tuberkulózis cf. tuberculosis bronchialis.^[100]

Problematic point(s): Inconsistency in some cases, cf. fitnesz for 'fitness' and wellness, or Milánó and Torino. Certain words, long present in Hungarian, are written in the foreign way (such as musical), despite their being commonly known, because of uncommon sound clusters in Hungarian (such as [mju] in *mjuzikel), or because of possible confusion with an existing Hungarian word (e.g. show for só 'salt'). Moreover, the traditional Hungarian transliteration may be rejected for languages like Chinese that already have a Latin version of their writing system. In addition, it may not be obvious whether a Latin or a non-Latin official language of a country should be considered as a basis (e.g. Indian names).

Some features of the original spelling are sometimes retained, e.g. football > futball (pronounced "fudbal"), million > millió (pronounced "milió"). The digraph ch is preserved if it is pronounced [h]. The letter x, if pronounced "ksz", is usually written x in Hungarian too. However, if it is pronounced "gz", it is normally written gz, again with a few exceptions. The letters qu are always respelled as kv.^[101]

If the source language uses a non-Latin script (Greek, Russian, Chinese etc.)^[102] words are respelled phonetically. This does not always mean exact transliteration: sometimes the foreign pronunciation is bent to conform to Hungarian phonology better (e.g. szamovár, tájfun 'samovar', 'typhoon').^[103] In practice however, English transliterations are often used instead, such as using gyros instead of gírosz).

Proper names

Proper names from languages with a Latin alphabet are normally written in the original way, e.g. Shakespeare, Horatius, Chopin, including all the diacritics (e.g. Molière, Gdańsk).^[104]

Certain foreign proper names have a Hungarian version, e.g. Kolumbusz Kristóf for Christopher Columbus (in the Eastern name order, typical of Hungarian). Other names adapted the given name and the word order to Hungarian customs, but left the surname intact, e.g. Verne Gyula for Jules Verne. Recently borrowed names are no longer modified in Hungarian. The only exceptions are some given names which can only be written in Hungarian spelling, e.g. Krisztián for Christian and Kármen for Carmen.^[105]

As with common nouns, ch and x are retained in both personal names and geographical names of foreign origin (e.g. Beatrix, Mexikó). Similarly to common names again, widely-known and fixed forms of proper names from languages with a non-Latin script are preserved (e.g. Ezópus (Aesop), Athén, Peking), rather than introducing a more up-to-date or more accurate transliteration (e.g. Aiszóposz, Athénai/Athína, Pejtying). Some well-established foreign names have a popular form used in phrases and another referring to the person (e.g. Pitagorasz tétele 'Pythagorean theorem' but Püthagorasz for the philosopher himself).^[106]

Suffixes

Suffixes are added directly in most cases. The -i suffix is omitted in writing if the word already ends in the letter i (e.g. Stockholm > stockholmi; Helsinki > helsinki). In the case of suffixes of variable forms depending on Hungarian vowel harmony rules, the version in accordance with the actual pronunciation should be used.^[107] If a certain suffix requires lengthening of the word-final vowels a, e, o, ö, they are lengthened as usual, e.g. Oslo but Oslóban, oslói.^[108] In addition, suffixes will follow the pronunciation of the word in terms of the ending consonant and the front or back vowels (e.g. Bachhal 'with Bach', Greenwichcsel 'with Greenwich').^[109]

If the last letter of a foreign word is silent (not pronounced) or part of a complex cluster of letters, a hyphen is used when attaching suffixes (e.g. guillotine-nal 'with a guillotine', Montesquieu-vel 'with M.').^[110] If an adjective is formed from a proper name with only one element, it will be lowercase (e.g. voltaire-es 'Voltaire-esque').^[110]

A hyphen is also used if an adjective is formed from a multiword name (e.g. Victor Hugó-i 'typical of V. H.', San Franciscó-i 'S. F.-based'). The last vowel is lengthened even in writing if it is pronounced and it is required by phonological rules.^[111] If the suffix begins with the same letter as a word-final double letter (e.g. Grimm-mel 'with Grimm').,^[112] a hyphen is used again.

At the end of a sentence

Punctuation marks are added to the end of the sentence depending on its intended meaning. The exclamation mark is not only used for exclamations, but also for wishes and commands. If the sentence formally reflects one mood, but it actually refers to a different idea, the punctuation mark is selected based on the actual meaning. Punctuation marks may be repeated or combined to express an intense or mixed emotion. (For example, Hogy képzeled ezt?! 'How dare you?!')^[127]

In case of coordinating clauses, the punctuation mark is adapted to the ending clause.^[128] Subordinated clauses take a punctuation mark reflecting the main clause – except if the main clause is only symbolic, emphasizing the subordinate clause.^[129]

Between clauses

A comma (or a colon, semicolon etc.) should be placed at the border of clauses whether or not there is a conjunction.^[130] It also applies to cases when the clause begins with one of the conjunctions és, s, meg 'and' and vagy 'or'. However, it is sometimes difficult to assess whether the part joined with these conjunctions is a separate clause (because if it is not, no comma is needed). For example: Bevágta az ajtót, és dühösen elrohant. 'He banged the door and rushed away in fury.' but Hirtelen felugrott és elrohant. 'He suddenly jumped up and rushed away.'^[131]

Similes introduced with the word mint 'as, like' are to be preceded by a comma. The exception is a kind of a 'more than' construction that has a mere intensifying function (as opposed to 'practically' or 'almost').^[132] In case of a double conjunction expressing 'instead of (doing)', 'without (doing)' etc., only the first element should be preceded by a comma – except if the first element closely belongs to the first clause, in which case the comma is placed between the two conjunctions.^[133]

Semicolons are generally used to separate sets of closely connected clauses, if these larger sets of clauses are loosely connected to each other. A semicolon may also be used to mark that two single clause have but a loose relation to each other.^[134]

Colons attract the attention to a forthcoming idea, or they may be used to mark that an important explanation or conclusion follows. If a clause introduces several separate sentences, all of them (including the first) are written with an uppercase initial.^[135]

To express that a fairly distinct set of ideas follows, a dash may be used after the full stop, the question mark, or the exclamation mark.^[136]

Between clause elements

Coordinated clause elements are separated by commas if no conjunction is used.^[137] (A semicolon may be used to separate series of words whose elements are separated by commas.)^[138] If a conjunction is used between coordinated clause elements, a comma is used before it,^[139] except if the conjunction is one of the words és, s, meg 'and' or vagy 'or,' where the comma is omitted. Since the abbreviation stb. 'etc.' includes the conjunction s 'and,' it doesn't need a comma either.^[140] For example: tetszetős, de helytelen elmélet 'an appealing but incorrect theory,' a rózsának, a szegfűnek vagy a levendulának az illata 'the scent of a rose, a carnation, or a lavender.'

If a coordinated sentence element is mentioned at the end of the whole clause, separated from the related elements, in a postponed manner, it is separated from the rest of the clause with a comma. For example: Ernyőt hozzál magaddal a kirándulásra, vagy kabátot! 'Bring an umbrella to the excursion, or a raincoat.'^[141] Coordinated structures formed with coupled conjunctions (e.g. "either – or") are written with a comma placed before the second conjunction.^[142]

Appositions are separated from the referred element with a comma (or a colon), if they are in the same grammatical position as the referred element. If the apposition gets further back in the sentence, the comma will precede it directly.^[143] If the apposition is followed by a pause in speech, a comma may be placed after it, too.^[144] If a descriptive phrase is added to a personal name but only the last part takes the suffixes (in which case it is not called an apposition), no comma is used after the personal name.^[145] For example: Nagy Elemérnek, városunk díszpolgárának 'to Elemér Nagy, honorary citizen of our town' – because of the possessive structure, both element take the suffixes, and the second part can only be an apposition, so a comma is needed. On the other hand: Nagy Elemér díszpolgárnak 'to Elemér Nagy honorary citizen' – the whole structure takes one suffix at the very end, thus it cannot be appositive, and no comma is used. If the apposition or the referred element is a derivative of the word maga ("himself" etc.), the comma is not used.^[146] However, adverbs used like appositions take the comma.^[147]

Subordinated clause elements take no comma (e.g. fekete szemüveges férfi 'a man with black glasses' – the word fekete 'black' doesn't belong to férfi 'man' but to szemüveg 'glasses').^[148] If the word mint 'as' precedes a phrase expressing status or quality, no comma is used before it (e.g. Bátyámat mint tanút hallgatták ki. 'My brother was heard as a witness.')^[149] Structures formed with an adverbial participle are not usually separated from the clause with a comma, especially if the participle is directly connected to it. However, if this part is loosely attached to the clause (especially if the participle has its own complement), it is recommended to use a comma.^[150]

Elements wedged into a clause

Between words and their elements

Interjections are preceded and followed by commas. If an interjection is followed by the emphatic words be or de 'how much,' the commas can be omitted depending on the stress and pause conditions of the sentence.^[160]

If two conjunctions follow each other (e.g. because of an interposed clause), only the first is preceded by a comma, e.g. Hívták, de mert hideg volt, nem indult útnak. 'They invited him, but as it was cold, he didn't set out.'^[161]

A hyphen is used between words and their elements in the following cases (a taxative list, partly reiterating points mentioned elsewhere):^[162]

• in case of three successive identical consonant letters at the border of compound elements and between a proper name and its suffix (see above)
• in certain kinds of word repetitions and coordinated compounds, in several types of subordinated compounds (see above), as well as in unusual, occasional compounds in the poetic language (e.g. bogáncs-szívem 'my heart of thistle')
• if the ending or beginning word of two or more compounds are the same, and only the last instance is written out in full: the preceding, omitted instances are marked with a hyphen, e.g. tej-, zöldség- és gyümölcsfelhozatal 'milk, vegetable, and fruits arrival,' bortermelő és -értékesítő szövetkezet 'cooperative for wine production and marketing'
• in numbers written in letters: beyond two thousand, if more numerals follow (see below)
• nouns and their derived adjectives are connected to proper names in several cases with a hyphen (see above)
• with double surnames (see above)
• with several types of geographical compounds (see above)
• with the enclitic question word -e (e.g. Tudod-e, merre menjünk? 'Do you know which way to go?')
• in case of pairs of numbers (whether in digits or in letters) given in an approximative sense (e.g. nyolc-tíz nap 'some eight or ten days')

The dash is referred to in Hungarian orthography under two names: gondolatjel (lit. "thought mark") and nagykötőjel (lit. "big hyphen"). The first form applies to cases where it separates an interposed remark, usually a clause or a phrase (see above): this one is always used with spaces on either side (or a comma and a space after it). The second one is used to connect single words with each other to create a phrase: this one is normally used without spaces. This latter dash is used between words in the following cases (a taxative list):^[163]

• to connect names of peoples or languages (e.g. francia–spanyol határ 'French-Spanish border')
• to link proper names in a loose, occasional (i.e. not institutionalized) relationship (like when authors of a book are mentioned after each other, or for matches of two sports teams)
• to express a relationship extending between two points (in time or space, e.g. Budapest–Bécs 'Budapest-Vienna [route]'). Note: the dash can exceptionally be surrounded by spaces in more complex cases, e.g. i. e. 753 – i. sz. 456 '753 BC – 456 AD'
• giving types of machines, between letters or words and a number (e.g. Apollo–11)

The ellipsis sign (...) is used to mark that an idea is unfinished (and more thoughts can be inferred from what is written), or if a part of a text has been omitted from a quotation.^[164]

Suffixation

Suffixes are normally attached to words directly. However, a hyphen is used in a couple of cases (a taxative list, referring to other passages of the regulation):^[165]

• in case of three successive identical consonant letters in certain cases that cannot be simplified, such as with proper names ending in double letters and having a suffix (see above)
• personal and geographical names as well as titles of periodicals consisting of several separate elements take adjective-forming derivational suffixes with a hyphen (see above), e.g. Leonardo da Vinci-s 'typical of L. da Vinci' (but Leonardo da Vincivel 'with L. da Vinci'), New York-i 'N. Y. C.-based' (but New Yorkban 'in N. Y. C.')
• proper names (including personal names, geographical names, institution names, titles of periodicals) with one single element take a hyphen before suffix-like derivational elements such as -szerű and -féle (e.g. Petőfi-szerű 'Petőfi-like,' cf. Petőfivel 'with Petőfi' and petőfis 'typical of Petőfi')
• if the word-final letter is not pronounced (silent), or this letter is part of a more complex cluster of letters, suffixes are connected with a hyphen (see above)
• digits, punctuation marks, typographical signs, abbreviations, and acronyms take a hyphen before suffixes (see below)

Other information on punctuation

No full stop is needed after titles of periodicals, books, poems, articles, studies, and treatises as well as after institution names and direction signs if they are given highlighted or on their own. However, lower section titles can be inserted in a text and they can be followed by other sentences: in this case, a full stop is used after them. Question and exclamation marks can be used even in highlighted titles.^[166]

A full stop is used in the following cases:^[167]

• after Roman and Arabic numerals denoting ordinal numbers (see below)
• after certain types of abbreviations (see below)
• after numbers marking the year, the month, and the day of a date (see below).

A colon is used to highlight a phrase or sentence mentioned as an example.^[168] This sign is also used between an author's name and the title of the work, if they are given without a syntactic reference to each other. A possessive case, however, eliminates the colon. (For example: Arany János: Toldi but Arany János Toldija 'Toldi by János Arany.')^[169]

A hyphen is used at the end of a line, when a part of a word is taken to the next line. If a word already contains a hyphen for whatever reason, it can be used at the end of the line, just like if it contains a dash.^[170]

If a part given in parentheses has a fairly close connection to the sentence, the closing punctuation mark is used after it. If the part in parentheses ends in a full stop, the punctuation mark still needs to be used after the parenthetical part.^[171]

Quotation marks may be used (though should not be overused) to express ironic or other emotional overtones.^[172] Quotation marks can be used around the titles of books, works, articles etc. – in this case, suffixes can be connected with a hyphen.^[173]

The beginning of decimal fractions is marked with a comma. Numerals of more than four digits are divided by spaces, in groups of three, counted from the back. (See more below.)^[174]

The following signs and symbols are also used relatively frequently (with minor differences from the Anglo-Saxon usage): plus (+) for addition, minus (–) for extraction, the interpunct ( · ) for multiplication, the colon ( : ) for division, the equals sign (=) to mean equality, the percent sign (%) to express percent, the slash (/) to express alternativeness or fractions, the section sign (§) to refer to sections, a combination of an upper dot, a slash, and a lower dot (⁒) to mean "please turn over," the asterisk or superscript numbers (* or ¹) to mark notes, a right double curly quote (") to express repetition (as opposed to ditto mark), a right single curly quote (') to express lack, the degree symbol to mark the (Celsius) degree, and the tilde (~) to express repetition or equivalence. Suffixes are connected to the percent sign, the section sign, and the degree symbol with a hyphen, and the suffix will reflect the pronounced form, with respect to assimilations and linking vowels, e.g. 3%-kal [pr. "három százalékkal"] 'by 3%.'^[175]

Abbreviations

Abbreviations are written in one word whether they are created from single nouns, nouns with derivational suffixes, or compounds, and they are written with a full stop. If an abbreviation retains the ending of the original word, the full stop is still preserved (e.g. pság. < parancsnokság 'headquarters'). Abbreviation of phrases normally contains as many elements as the original phrase contains (e.g. s. k. < saját kezével 'by his/her own hand') but there are exceptions (e.g. vö. < vesd össze 'compare'). Case is usually kept in abbreviations (e.g. Mo. < Magyarország 'Hungary') but some abbreviations created from lowercase words use the uppercase (e.g. Ny < nyugat 'west'). Units of measurement are used in accordance with the international standard, depending on whether the sign comes from a common name (m < méter) or a proper name (N < newton after Isaac Newton). Standard forms of abbreviations are not to be altered even in full-capitalized inscriptions (ÁRA: 100 Ft 'PRICE: 100 HUF').^[177]

Some abbreviations are written without a full stop, such as names of currencies, cardinal and ordinal directions, country codes of cars, codes of country names, chemical, physical, mathematicals symbols, symbols of units, etc. The full stop can be omitted from abbreviations in encyclopedias, but they are to be explained in a legend. A full stop is not used after abbreviations whose last element is a full word (e.g. uaz < ugyanaz 'the same').^[178]

Suffixes are attached to abbreviations based on their pronunciation (even if the pronunciation is considerably different from the symbol, e.g. F [vas 'iron'] > Fe-sal [vassal 'with iron'], and the article, too, should reflect the pronounced form).^[179] If an abbreviation forms a compound with a full word, they are connected with a hyphen (e.g. fszla.-kivonat < folyószámla-kivonat 'statement of current account').^[180]

Acronyms

Acronyms are classified into two groups: those consisting only of initials (betűszók lit. 'letter-words'), and those consisting parts of the original word (szóösszevonások 'word contractions').

The first group is divided again by whether they denote proper names (written in uppercase, e.g. ENSZ < Egyesült Nemzetek Szövetsége 'United Nations Organization', note that both letters of the digraphs SZ are capitalized) or common names (written in lowercase, e.g. vb < végrehajtó bizottság 'executive committee', note that it is written as one word despite the two elements). Some acronyms created from common names are still written in uppercase, though, especially in sciences (URH < ultrarövidhullám 'ultra-high-frequency') but other capitalized acronyms may be accepted too (TDK < tudományos diákkör 'students' scholarly circle'). In some cases, full-fledged words are created from the pronounced form of acronyms standing for common names (e.g. tévé < tv < televízió).^[181]

Since 2015, a hyphen is required even if the additional word is already contained in the acronym (e.g. CD-lemez literally 'CD disk', though CD already comprises "disk", versus CD-írás 'CD burning', in accordance with earlier regulations).

Acronyms of the second group are created from longer parts of the original words (in fact, at least one word of the original should keep at least two letters, not including digraphs). Their letters are not all capitalized, only the initial of acronyms that derive from proper names (e.g. Kermi < Kereskedelmi Minőség-ellenőrző Intézet, 'Commercial Quality Control Institute' cf. gyes < gyermekgondozási segély 'maternity benefit').^[182]

Neither type of acronyms need a full stop between their elements or at their end.^[183]

Acronyms take suffixes in accordance with their pronounced forms, whether their letters are pronounced one by one or as a full word (e.g. tbc-s [tébécés] 'one with tuberculosis'). Those from the first group, consisting only of word initials, are suffixed with a hyphen. Their capitalized types will retain their uppercase even in their adjectival forms (ENSZ-beli 'one from the UN'), and their ending vowel letter will not be lengthened even if it would be phonologically justified (e.g. ELTE-n [eltén] 'at ELTE'). Those from the second group, however, consisting of shorter pieces of the constituting words, take suffixes without a hyphen (e.g. gyesen van 'she is on maternity leave'). The same happens to those words that were created from pronounced letters (e.g. tévézik 'watch TV'). Proper name types of these acronyms are written in lowercase if an adjective is formed out of them (e.g. kermis 'Kermi-related'). In addition, their ending vowel letter may be lengthened in accordance with general phonological rules (e.g. Hungexpo > Hungexpónál 'at Hungexpo').^[184]

Compounds are created with acronyms by the following rules: those from the first group take other elements with a hyphen (e.g. URH-adás 'UHF broadcast'), and proper name types of the second group behave the same way (e.g. Kermi-ellenőrzés 'control by Kermi'). The common name types of the second group, however, can be written as one word with other elements, except if they require a hyphen because of length (e.g. tévéközvetítés 'TV transmission').^[185]

Numbers

Numerals that can be pronounced with a short word are usually written in letters, just like those having a suffix, a postposition, or another compound element. On the other hand, digits should be used in case of longer or bigger numerals, as well as to note down exact quantities, dates, amounts of money, measurement, statistical data etc.^[186]

If cardinal numbers are written in letters, they should be written as one word up to 2000 (e.g. ezerkilencszázkilencvenkilenc '1,999') and they should be divided by hyphens by the usual three-digit division over 2000 (e.g. kétezer-egy '2,001'). Numbers written in digits can be written without a space up to four digits; above that, they are divided by spaces from the end by the usual three-digit division (e.g. 9999 but 10 000). If numbers are written under each other in a column, all can be divided by spaces.^[187]

Ordinal numbers written in digits take a full stop (e.g. 3. sor '3rd line'). The full stop is retained even before the hyphen that connects suffixes (e.g. a 10.-kel 'with the 10th'). Dates are an exception to this rule, see below.^[188]

If a fraction functions as a noun, the quantifier is written separately (e.g. egy negyed 'one quarter'). However, if a fraction takes an adjectival role in a phrase, the two parts are written in one word (e.g. egynegyed rész 'a one-quarter part'). Giving the hour is also done by this rule. The integer part of a decimal is divided from the rest by a comma (e.g. 3,14 '3.14').

Numbers are usually written in Arabic numerals. Roman numerals are only used in some special traditional cases, only to express ordinal numbers (e.g. to express the numbering of monarchs, popes, districts of a city, congresses, etc.). Their use is advisable if they have a distinctive role as opposed to Arabic numbers, e.g. to denote the month between the year and the day, or to mark the floor number in front of the door number.^[189]

Dates

The year is always given in Arabic numerals and it is followed by a full stop. The name of the month can be written in full or abbreviated, or it can be marked with a Roman or Arabic numeral. The day is always written in Arabic numerals. Dates are sometimes written without full stops and spaces, divided only by hyphens.^[190]

Normally, a full stop is needed after the year.^[191] However, it is omitted in three cases: (1) if it is in a possessive relationship with the forthcoming word, (2) if it is followed by a postposition or an adjective coined from it, or (3) if it is the subject of a sentence or it stands solely in parentheses. For example, 1994. tavasz 'the 1994 spring' but 1994 tavasza 'the spring of 1994' and 1994 után 'after 1994.'^[192]

When digits expressing year and day take suffixes, the full stop is dropped before the hyphen (e.g. 1838-ban 'in 1838' and március 15-én 'on March 15'). The word elsején 'on the 1st of' and its suffixed forms are abbreviated as 1-jén etc.^[193] If a day is followed by a postposition, the full stop is retained (e.g. 20. és 30. között 'between the 20th and the 30th').^[194]

Other cases

Letters and other postal consignments are to be addressed by the official addressing patterns of the Hungarian Postal Service. (It currently means that the name comes first, then the settlement, the street or the P.O.B., and finally the postcode, written under each other. Street directions contain the street number first, and optionally the floor number and the door number.)^[195]

The words for "hour" and "minute" (óra and perc) are not usually abbreviated in fluent texts. If the time is given in digits, a full stop or a hyphen is placed between the hour and the minute without a space (e.g. 10.35). This latter form takes a hyphen before suffixes (e.g. 10.35-kor 'at 10:35').^[196]
