The Hungarian alphabet (Hungarian: magyar ábécé) is an extension of the Latin alphabet used for writing the Hungarian language.

The alphabet is based on the Latin alphabet, with several added variations of letters, consisting 44 letters. Over the 26 letters of the ISO basic Latin alphabet it has five letters with an acute accent, two letters with an umlaut, two letters with a double acute accent, eight letters made up of two characters, and one letter made up of three characters. In some other languages, characters with diacritical marks would be considered variations of the base letter, however in Hungarian, these characters are considered letters in their own right.^[1]

One sometimes speaks of the smaller (or basic) and greater (or extended) Hungarian alphabets, differing by the inclusion or exclusion of the letters Q, W, X, Y, which can only be found in foreign words and traditional orthography of names, and whether the uncommon digraphs Dz and Dzs are counted as a distinct letter. (As for Y, however, it exists as part of several digraphs.)

As an auxiliary letter sometimes Ë is used in academic documents to show different pronunciation of spoken dialects, though it is not part of the alphabet.^[2]

Each sign shown above counts as a letter in its own right in Hungarian. Some, such as the letter ⟨ó⟩ and ⟨ő⟩, are inter-filed with the letter preceding it when sorting words alphabetically, whereas others, such as ⟨ö⟩, have their own place in collation rather than also being inter-filed with ⟨o⟩.

While long vowels count as different letters, long (or geminate) consonants do not. Long consonants are marked by duplication: e.g. ⟨tt⟩, ⟨gg⟩, ⟨zz⟩ (ette 'he ate' (det.obj.), függ 'it hangs', azzal 'with that'). For the di- and tri-graphs a simplification rule normally applies (but not when the compound is split at the end of a line of text due to hyphenation), only the first letter being duplicated, e.g.

⟨sz⟩ + ⟨sz⟩ → ⟨ssz⟩ (asszony 'woman'),

⟨ty⟩ + ⟨ty⟩ → ⟨tty⟩ (hattyú 'swan'),

⟨dzs⟩ + ⟨dzs⟩ → ⟨ddzs⟩ (briddzsel 'with bridge (playing game)').

An exception is made at the joining points of compound words, for example: jegygyűrű 'engagement ring' (jegy + gyűrű) rather than *jeggyűrű.

Hyphenation of individual letters ⟨Dz⟩ and ⟨dzs⟩ were changed in the 11th edition of Hungarian orthography (1984).^[3] Prior to that, they were allowed to separate as two-letter combinations ⟨d⟩+⟨z⟩ and ⟨d⟩+⟨zs⟩.

The pronunciation given for the following Hungarian letters is that of standard Hungarian.

The letter ë is not part of the Hungarian alphabet; however, linguists use this letter to distinguish between the two kinds of short e sounds of some dialects. This letter was first used in 1770 by György Kalmár, but has never officially been part of the Hungarian alphabet, as the standard Hungarian language does not distinguish between these two sounds. However, the ë sound is pronounced differently from the e sound in 6 out of the 10 Hungarian dialects and the sound is pronounced as ö in 1 dialect. It is also used in names. Other letter for this sound is Ėė (rarely).

A more open variety of /ɛ/, close to [æ], amy be denoted as Ää in the Hungarian linguistics literature.

The digraph ch also exists in some words (technika, monarchia) and is pronounced the same as h. In names, however, it is pronounced like cs as well as like h or k (as in German) (see below).

The letter Y is only used in loanwords and several digraphs (gy, ly, ny, ty), and thus in a native Hungarian word, Y never comes as the initial of a word, except in loanwords. So, for native Hungarian words, the capital Y only exists in all caps or small caps formats, such as the titles of newspapers.

The di- and the trigraphs are capitalised in names and at the beginning of sentences by capitalising the first glyph of them only.

• Csak jót mondhatunk Székely Csabáról.

In abbreviations and when writing with all capital letters, however, one capitalises the second (and third) character as well.

• MHSZ (not MHSz)
• A MAGYAR HELYESÍRÁS SZABÁLYAI (not SzABÁLyAI)

While the characters with diacritical marks are considered separate letters, vowels that differ only in length are treated the same when ordering words. Therefore, for example, the pairs O/Ó and Ö/Ő are not distinguished in ordering, but Ö follows O. In cases where two words are differentiated solely by the presence of an accent, the one without the accent is put before the other one. (The situation is the same for lower and upper-case letters: in alphabetical ordering, varga is followed by Varga.)

The polygraphic consonant signs are treated as single letters.

The simplified geminates of multigraphs (see above) such as <nny>, <ssz> are collated as <ny>+<ny>, <sz>+<sz> etc., if they are double geminates, rather than co-occurrences of a single letter and a geminate.

könnyű is collated as <k><ö><ny><ny><ű>. tizennyolc of course as <t><i><z><e><n><ny><o><l><c>, as this is a compound: tizen+nyolc ('above ten' + 'eight' = 'eighteen').

Similar 'ambiguities', which can occur with compounds (which are highly common in Hungarian) are dissolved and collated by sense.

e.g. házszám 'house number (address)' = ház + szám and of course not *házs + *zám.

These rules make Hungarian alphabetic ordering algorithmically difficult (one has to know the correct segmentation of a word to sort it correctly), which was a problem for computer software development.

The standard Hungarian keyboard layout is German-based (QWERTZ). This layout allows direct access to every character in the Hungarian alphabet.

The letter "Í" is often placed left of the space key, leaving the width of the left Shift key intact. "Ű" may be located to the left of Backspace, making that key smaller, but allowing for a larger Enter key. Ű being close to Enter often leads to it being typed instead of hitting Enter, especially when one has just switched from a keyboard that has Ű next to backspace. The German "Ä" and "ß", the Polish "Ł", and the Croatian "Đ" are also present.

The most common letters in Hungarian are e and a.^[7]

The Old Hungarian script is a writing system formerly used for the Hungarian language. It was derived from the Old Turkic script.^[10] Its usage began to decline after the Kingdom of Hungary adopted the Latin alphabet.

Epigraphic evidence for the use of the Old Hungarian script in medieval Hungary dates to the 10th century.^[11] At the turn of the 11th century, with the coronation of Stephen I of Hungary, Hungary became a kingdom and the Latin alphabet was adopted as official script.

The runic script was first mentioned in the 13th century Chronicle of Simon of Kéza,^[12] where he stated that the Székelys may use the script of the Blaks.^[13][14][15] Johannes Thuróczy wrote in the Chronica Hungarorum that the Székelys did not forget the Scythian letters and these are engraved on sticks by carving.^[16]

Its usage between the 11th and 19th centuries is believed to have been limited, although it featured in folk art of the Early Modern period. The script experienced a revival in the 20th century. Beginning with Adorján Magyar in 1915, the script has been promulgated as a means for writing modern Hungarian.
