The Hungarian vowels e, é, i, í are front and unrounded, yet they are often called neutral in vowel harmony. “Neutral” does not mean that they never affect a suffix. Most stems containing only these vowels take front suffixes, but the same vowels can let an earlier back vowel control in a mixed stem, and a small inherited group behaves as back harmonic without containing any back vowel at all.
This page gives the formal architecture behind those outcomes. The usage page develops them in conversation and formal contexts, while the contrasts page treats difficult choices and variation. Unless stated otherwise, forms here belong to neutral modern standard Hungarian.
What “neutral” means
Hungarian harmony first distinguishes back vowels a, á, o, ó, u, ú from front vowels. Within the front set, ö, ő, ü, ű are rounded and reliably signal front harmony. The unrounded front vowels e, é, i, í behave less categorically.
| Stem type | Typical behavior | Example |
|---|---|---|
| only neutral vowels, regular | front suffix | vízben, széken |
| only neutral vowels, inherited exception | back suffix | hídban, hídon |
| back vowel followed by neutral vowel | often remains back | papírban, tányéron |
| mixed loan with final neutral vowel | lexically front or variable | koncerten, projektben |
| compound | normally follows final member | útlevélben, szemüvegtokban |
The term disharmonic describes a stem or suffixed word whose vowels do not all belong to the expected harmonic set. Across stem and suffix, papírban has the sequence back a — front í — back a, yet it is fully standard. Disharmony is a structural description, not a pronunciation mistake.
Most all-neutral stems are front harmonic
When a stem contains only e, é, i, í, the productive default is front harmony. This gives vízben “in the water,” székhez “to the chair,” and pénzen “on the money.” Because these vowels are unrounded, a three-way suffix uses its front unrounded member: -hez rather than -höz, -en rather than -ön.
A kulacsban még van víz, de a vízben jégdarabok úsznak.
There is still water in the bottle, but pieces of ice are floating in it.
Tedd vissza a széket az íróasztal mellé!
Put the chair back beside the desk!
Erre a címre küldd el a részletes jelentést.
Send the detailed report to this address.
The last example includes several neutral-vowel stems: címre, részletes, jelentést. Their front behavior is ordinary, not exceptional. English supplies no comparable evidence because its prepositions and endings do not change according to the noun's vowels.
Inherited back-harmony exceptions
A small, frequent set of all-neutral stems selects back suffixes. Híd gives hídon, hídhoz, hídban; nyíl gives nyíllal, nyílhoz; díj gives díjnak, díjjal. These classes reflect the words' history and lexical behavior, not their present written vowels.
| Stem | “in/on” | “to” | dative |
|---|---|---|---|
| víz, regular front | vízben / vízen | vízhez | víznek |
| híd, lexical back | hídban / hídon | hídhoz | hídnak |
| papír, mixed back | papírban / papíron | papírhoz | papírnak |
| koncert, mixed front | koncerten | koncerthez | koncertnek |
A villamos a hídon állt meg néhány percre.
The tram stopped on the bridge for a few minutes.
A nyíl a céltábla közepébe fúródott.
The arrow lodged in the center of the target.
Cél itself is another all-neutral back-harmony stem: célnak, célhoz. There is no dependable meaning-based test that predicts this group. Learn an exceptional noun with one revealing form, such as híd — hídhoz, rather than memorizing its bare form alone.
Neutral vowels in mixed stems
After a back vowel, neutral vowels can be transparent: the earlier back vowel continues to control the suffix. This is especially common when final i/í follows a back vowel, as in papírban, and also occurs in familiar words with é, such as kávéval and tányéron.
A számlát véletlenül leöntöttem kávéval.
I accidentally spilled coffee on the bill.
A tányéron maradt süteményt tedd be a hűtőbe!
Put the cake left on the plate in the refrigerator!
Neutrality is gradient rather than absolute. Final i/í is highly likely to remain transparent after a back vowel; é and especially e more readily support front suffixes. Even that tendency is not a mechanical spelling rule, however. Lexical history, the number of neutral vowels, and familiarity all affect mixed stems. Papír is back, whereas established loans such as koncert and projekt take front suffixes in standard use.
A koncerten bemutatták az új zenei projektet.
They presented the new music project at the concert.
Compounds and suffix chains
A true compound normally takes its harmony from its final meaningful member. The earlier member does not compete with the suffix: út + levél + -ben → útlevélben, because levél is front harmonic; szemüveg + tok + -ban → szemüvegtokban, because tok is back harmonic.
Az útlevélben hibásan szerepel a születési helyem.
My place of birth is listed incorrectly in the passport.
A pótcsavarokat a szemüvegtokban találtam meg.
I found the spare screws in the glasses case.
Once a suffix is attached, its vowel can be the closest relevant vowel for a later suffix, but different suffix families still obey different inventories. Főnökünkhöz contains the possessive -ünk followed by rounded -höz. This is local rounding after an already suffixed stem, not evidence that neutral vowels have become rounded.
Forms that reveal—or conceal—the class
Not every ending provides evidence about harmony. Invariant -ig has the same form in vízig “as far as the water” and hídig “as far as the bridge.” A direct accusative can also hide the choice: papírt contains no alternating suffix vowel. By contrast, -hoz/-hez/-höz, -ban/-ben, and -on/-en/-ön reveal the class immediately.
A hídtól a parkig gyalog mentünk tovább.
We continued on foot from the bridge as far as the park.
For vocabulary learning, an invariant or vowel-less ending is therefore a poor diagnostic. Pair a new neutral-vowel stem with a visibly alternating suffix. Recording híd—hídhoz and papír—papíron prevents a later guess based only on the final written vowel.
Segmentation exercise
Separate each word into its meaningful pieces and identify the controller.
- vízhez = víz + -hez: a regular all-neutral front stem.
- hídon = híd + -on: an all-neutral lexical back stem.
- papírból = papír + -ból: back a remains active through neutral í.
- koncerten = koncert + -en: an established mixed loan with front suffixes.
- útlevélben = út + levél + -ben: final compound member levél controls.
- szemüvegtokhoz = szemüveg + tok + -hoz: final compound member tok controls.
This sequence exposes four separate sources of suffix choice: the productive front default, inherited lexical backness, transparency in mixed stems, and compound structure.
Common Mistakes
1. Treating every all-neutral stem as back harmonic.
❌ A szomjas kutya odafutott a vízhoz.
Incorrect — víz is a regular front-harmony stem and takes -hez.
✅ A szomjas kutya odafutott a vízhez.
The thirsty dog ran over to the water.
2. Forcing the front form after exceptional híd.
❌ A hídhez vezető utcát lezárták.
Incorrect — híd belongs to the lexical back-harmony class.
✅ A hídhoz vezető utcát lezárták.
The street leading to the bridge has been closed.
3. Letting final í override the back vowel in papír.
❌ A levelet sárga papírbe csomagolták.
Incorrect — papír takes back-harmony -ba.
✅ A levelet sárga papírba csomagolták.
They wrapped the letter in yellow paper.
4. Applying transparency to every mixed loan.
❌ A projektban több külföldi szakértő dolgozik.
Incorrect — established projekt takes the front inessive -ben.
✅ A projektben több külföldi szakértő dolgozik.
Several foreign experts are working on the project.
Key Takeaways
Most stems made only of e, é, i, í take front unrounded suffixes. Some inherited stems, including híd, nyíl, díj, cél, are lexically back harmonic. In mixed stems, neutral vowels may let an earlier back vowel control, but the degree of transparency is not categorical and loans must be learned from established usage. Compounds normally follow their final member. Backness, local rounding, linking vowels, and lexical stem class are connected layers, not one nearest-vowel formula.
