Obligatory Diacritics and Vowel Length: Forms and Core Pattern | Hungarian Grammar

Hungarian accents are part of the alphabet, not optional pronunciation hints. The standard language has seven short vowel letters—a, e, i, o, ö, u, ü—and seven corresponding long letters—á, é, í, ó, ő, ú, ű. Changing or removing a mark can produce a different word, a nonexistent form, or the wrong suffix.

This page establishes the written system. The companion usage page shows how vowel spelling functions in messages and longer texts, while the contrasts page handles difficult choices.

The fourteen vowel letters

The acute accent marks the long members á, é, í, ó, and ú. The umlaut on ö and ü marks front rounded vowel quality; their long partners ő and ű have a double acute accent. Do not replace the double acute with a circumflex or tilde: ő is not ô or õ, and ű is not û.

Short letter	Long letter	Lexical contrast	Meanings
a	á	bal – bál	left – ball/dance
e	é	ver – vér	beats – blood
i	í	irt – írt	eradicates – wrote
o	ó	kor – kór	age/era – disease
ö	ő	tör – tőr	breaks – dagger
u	ú	szurok – szúrok	pitch/tar – I stab/prick
ü	ű	füzet – fűzet	notebook – has something threaded/bound

For i/í, o/ó, ö/ő, u/ú, and ü/ű, length is the main contrast. The pairs a/á and e/é also differ substantially in vowel quality: á is not merely an a held longer, and é is not merely a prolonged e. English speakers should therefore learn each pair as two Hungarian vowels, not as one basic vowel plus optional stress.

A bál után balra fordultunk.

After the dance, we turned left.

Akár egy órát is vár, ha találkozni akar veled.

She will wait even an hour if she wants to meet you.

Öt percig kerestem őt a pályaudvaron.

I looked for him at the station for five minutes.

Tegnap hosszú levelet írt a nővérének.

Yesterday he wrote a long letter to his older sister.

Az őr egy régi tőrt talált a kapu mellett.

The guard found an old dagger beside the gate.

These sentences are standard in both (formal) and (informal) contexts. Their diacritics do not change with register.

💡

An accent in Hungarian belongs to a vowel letter. It normally marks length, while ö/ü also mark rounding and á/é differ in quality from a/e. It never marks word stress: ordinary Hungarian word stress remains on the first syllable.

Length is lexical, not decorative

English readers can often ignore a borrowed accent without changing the identity of an English word. Hungarian does not work that way. Koros means “aged,” while kóros means “pathological”; oda means “to there,” while óda means “ode.” The reader uses the vowel letter to identify the word.

Ez az eltérés nem kóros, csak az idős korral jár.

This difference is not pathological; it simply comes with old age.

Tedd oda a kötetet az ódák mellé.

Put the volume over there beside the odes.

A sűrű szurokhoz ne nyúlj hozzá puszta kézzel!

Do not touch the thick tar with your bare hands!

There is no rule that lets a learner reconstruct every stem vowel from meaning. The secure method is to store the diacritics with the citation form: learn tűz, not “tuz plus an accent to add later,” and gyönyörű, not an ASCII skeleton.

Vowel harmony chooses suffix vowels

Many suffixes have harmonic variants. Back-vowel stems generally select a back suffix, front unrounded stems a front suffix, and some suffix families also distinguish front rounded stems.

Function	Back	Front unrounded	Front rounded
in	házban	kertben	földben
to/toward	házhoz	kézhez	földhöz
from inside	házból	kézből	földből
from/by	háztól	kéztől	földtől

The marks inside a suffix are fixed. The elative suffix is -ból/-ből, never standard -bol/-böl. The allative family -hoz/-hez/-höz has short vowels, so writing -hőz would be equally wrong. Harmony determines which vowel quality appears; it does not license changing that vowel’s length.

A könyvtárból egyenesen a pékséghez megyek.

I’m going straight from the library to the bakery.

Ne állj ilyen közel a tűzhöz!

Do not stand this close to the fire!

The second example also shows morpheme preservation. It is built from tűz + -höz. The final z can sound devoiced before h in fluent speech, but standard writing keeps the stem tűz intact. Vowel harmony selects rounded-front -höz, and both ű and ö remain obligatory.

Stem alternations: a real memorization task

Some stems shorten a long vowel before particular suffixes: víz → vizek, kéz → kezek, út → utak, and tűz → tüzet. Other apparently similar stems keep the long vowel: ház → házak and szék → székek. These are morphological stem classes, not cases of casual accent dropping.

Két út vezet oda, de az egyik utat lezárták.

Two roads lead there, but one of the roads has been closed.

Rakj még egy széket az asztalhoz; a székek a másik szobában vannak.

Put another chair by the table; the chairs are in the other room.

There is no fully reliable shortcut that predicts every shortening stem. Learn common sets together—víz, vizek, vizet—and do not generalize from út, utak to unrelated words.

Multigraphs and consonant length remain intact

Diacritics solve the vowel problem only. Hungarian consonant multigraphs such as gy, ny, sz, zs, and dzs are single alphabetic letters, and long consonants are meaningful too. Copy the whole word: gyönyörű contains gy, ny, ö, ö, ű; jegygyűrű preserves two complete gy letters at a compound boundary.

A gyönyörű jegygyűrűt a fiókban őrzi.

She keeps the beautiful wedding ring in the drawer.

💡

Check vowels and consonants separately. A correct ű does not repair a missing gy, and a correct multigraph does not repair gyonyoru. Hungarian spelling encodes both vowel identity and consonant structure.

Reliable keyboard entry

Install a Hungarian keyboard layout or add Hungarian as an input language. On most phone keyboards, holding o or u opens accented choices; select the actual ő or ű. Desktop layouts provide dedicated Hungarian vowel keys or an input method supplied by the operating system. Capital letters keep their marks: Á, É, Í, Ó, Ö, Ő, Ú, Ü, Ű.

Visually similar substitutions are wrong in standard text. A search engine may understand turo for túró, but the spelling is still túró. In stored text, copy-and-paste workflows should also preserve the genuine Unicode characters ő and ű rather than õ and û.

Segmentation exercise

Separate each form into stem and suffix, then explain every accented vowel.

házból
földhöz
tűzhöz
tüzet
jegygyűrűt

Answers:

ház + -ból: the stem has á; the back-vowel elative suffix has long ó.
föld + -höz: ö is part of the stem, and rounded-front harmony selects short ö in -höz.
tűz + -höz: the stem has long ű; the suffix has short ö; the written z is preserved despite possible devoicing.
tűz + -et → tüzet: this stem shortens ű to ü before the object suffix.
jegygyűrű + -t: the compound preserves gy + gy, and both vowels in gyűrű are long ű.

Common Mistakes

1. Treating all acute accents as optional stress marks.

❌ Tegnap levelet irt.

Incorrect — irt means eradicates; the past form of ír requires í.

✅ Tegnap levelet írt.

Yesterday he wrote a letter.

2. Replacing the double acute with an umlaut.

❌ Ne menj közel a tüzhöz!

Incorrect — the stem is tűz with a long front rounded vowel.

✅ Ne menj közel a tűzhöz!

Do not go close to the fire!

3. Copying stem length through a shortening alternation.

❌ Ezt az útot választjuk.

Incorrect — út has the object form utat.

✅ Ezt az utat választjuk.

We are choosing this route.

4. Breaking a multigraph while correcting the vowels.

❌ Nagyon szép a jegyűrűd.

Incorrect — the compound jegy plus gyűrű preserves both gy letters.

✅ Nagyon szép a jegygyűrűd.

Your wedding ring is very beautiful.

Key Takeaways

Treat a, á, e, é, i, í, o, ó, ö, ő, u, ú, ü, and ű as fourteen distinct vowel letters.
Use vowel harmony to choose a suffix variant, but retain that suffix’s fixed length: -ból/-ből is long and -hoz/-hez/-höz is short.
Learn shortening stems in pairs such as víz – vizet while preserving multigraphs and consonant length independently.
