The core three-way choice is back – front unrounded – front rounded: -hoz – -hez – -höz. The most common learner error is to notice ö or ü somewhere in a stem and round every following suffix. Hungarian rounding harmony is much narrower. It applies locally, only in suffix families that actually possess a rounded member, and only after the stem’s front–back class is known.
This page contrasts those environments with their nearest alternatives. The complete core patterns are on the forms page, and extended communicative uses are on the usage page.
Matched three-way sets
These sets hold grammatical meaning constant while the stem changes harmonic class:
| Meaning | Back | Front unrounded | Front rounded |
|---|---|---|---|
| toward/to | házhoz | székhez | földhöz |
| on/at | asztalon | széken | földön |
| number of times | háromszor | kétszer | ötször |
A futár először a házhoz, aztán az üzlethez, végül a kikötőhöz ment.
The courier went first to the house, then to the shop, and finally to the harbor.
A levél az asztalon, a kabát a széken, a táska pedig a földön van.
The letter is on the table, the coat is on the chair, and the bag is on the floor.
Háromszor telefonáltam, kétszer írtam, és ötször néztem meg a postaládát.
I called three times, wrote twice, and checked the mailbox five times.
The same meanings recur across each row. The vowels reflect the Hungarian stems, not different shades of “to,” “on,” or “times.”
Three-way suffix versus two-way suffix
The presence of a rounded stem vowel does not prove that the next suffix will contain ö. The allative and superessive have rounded front forms, but the inessive and dative do not:
| Stem | Three-way family | Two-way family |
|---|---|---|
| föld | földhöz, földön | földben, földnek |
| könyv | könyvhöz, könyvön | könyvnek, könyvben |
| tükör | tükörhöz, tükrön | tükörben, tükörnek |
The superessive tükrön also shows a stem alternation: tükör loses its second vowel before this suffix. The suffix is still rounded -ön, but the current stem is tükr-.
A tükörben látszik egy folt, a tükrön pedig apró repedés van.
A stain is visible in the mirror, and there is a small crack on the mirror itself.
A főnöknek küldtem az üzenetet, aztán személyesen is odamentem a főnökhöz.
I sent the message to the boss and then went over to the boss in person.
English uses “in/on” and “to” to signal the relation, but it offers no clue about how many Hungarian allomorphs the chosen suffix possesses. Learn the suffix family before applying harmony.
Last rounded vowel versus last relevant vowel
For an ordinary front stem with a three-way suffix, the final vowel controls rounding locally. Tükör ends in rounded ö, so it gives tükörhöz. Füzet begins with rounded ü but ends in unrounded e, so it gives füzethez.
A füzethez vékony ceruzát, a tükörhöz erős ragasztót vettem.
I bought a thin pencil for the notebook and strong glue for the mirror.
The rule uses the last vowel, not the nearest rounded vowel. A following suffix can become the new local controller: főnök-ünk-höz has rounded ü immediately before the allative, while főnök-ség-hez has unrounded é.
A kérdést a főnökünkhöz intézték, a hivatalos levél viszont a főnökséghez érkezett.
They addressed the question to our boss, but the official letter arrived at management.
This locality is categorical in standard three-way suffixes. Do not skip an intervening unrounded vowel to recover an earlier ö.
Rounding versus lexical backness
Backness must be decided before rounding. The stem híd contains only front unrounded í, yet it belongs lexically to the back-harmony class: hídhoz, hídon. It therefore never reaches the front -hez/-höz choice. By contrast, víz is front harmonic: vízhez, vízen.
A hídtól a vízhez vezető út a dombon folytatódik.
The road leading from the bridge to the water continues over the hill.
This is why “choose from the closest written vowel” fails. The closest vowel in both híd and víz is í, but lexical class sends them to different branches of the system.
Rounding versus linking-vowel class
Plural linking vowels can resemble a three-way suffix: asztalok, székek, őrök. They are not governed by rounding alone. The rounded stems könyv and föld have könyvek and földek, not könyvök and földök. Yet genuinely three-way suffixes remain rounded: könyvhöz, könyvön, földhöz, földön.
A könyvek a polcon vannak; lépj közelebb ahhoz a könyvhöz, amelyikre mutatok!
The books are on the shelf; step closer to the one I’m pointing out.
Az őrök a földön heverő térképeket vizsgálták.
The guards examined the maps lying on the ground.
There is no contradiction. The plural vowel belongs partly to a lexical stem class; the allative and superessive implement local three-way harmony. Learn small paradigms such as könyv – könyvek – könyvhöz – könyvön.
Visible three-way ending versus bare -n
The superessive has visible -on/-en/-ön after many consonant-final stems, but after many vowel-final nouns it appears as -n: autón, kávén, tetőn, menün. With final a/e, the stem vowel lengthens: utca → utcán, lecke → leckén.
A menün szereplő ár nem egyezik a számlán lévő összeggel.
The price shown on the menu does not match the amount on the bill.
Do not invent menüön by applying the consonant-stem pattern. The shape of the stem–suffix boundary matters alongside harmony.
Information structure changes prominence, not allomorphy
Focus can place strong stress on a suffixed word, but the suffix vowel remains grammatical:
A FŐNÖKHÖZ megyek, nem az ügyvédhez.
I’m going TO THE BOSS, not to the lawyer.
The capitals represent emphatic speech (informal). Ordinary edited prose would use standard capitalization, but both versions require főnökhöz and ügyvédhez. Acute and double-acute marks remain part of the vowels; they do not encode the focus.
Register also leaves harmony unchanged. An official instruction (formal), a scholarly analysis (academic), and a quick message (informal) use the same suffix allomorphs. Recent loanwords may show genuine variation while they become lexically established, but that variation should not be recast as a blanket casual rule.
Decision tree
- Identify the suffix and its meaning. Case selection comes before phonological shape.
- Count its listed forms. One form: no harmony. Two forms: back versus front only. Three forms: continue to rounding.
- Determine the current stem’s front–back class. Check mixed and all-neutral lexical exceptions such as híd.
- If the stem is back, choose the back member: -hoz, -on, -szor.
- If the stem is front, inspect its last vowel. Unrounded e, é, i, í select -hez/-en/-szer; rounded ö, ő, ü, ű select -höz/-ön/-ször.
- Check the boundary shape and stem class. Vowel-final nouns may take bare -n; linking-vowel paradigms such as plurals require lexical information.
Diagnostic exercise
Choose the correct form and explain why.
- “to the notebook”: füzethez / füzethöz
- “to the mirror”: tükörhez / tükörhöz
- “in the suitcase”: bőröndben / bőröndbön
- “to the bridge”: hídhez / hídhoz
- “books”: könyvek / könyvök
- “on the menu”: menün / menüön
Answers:
- Füzethez: final e is front unrounded.
- Tükörhöz: final ö is front rounded.
- Bőröndben: the inessive has only two forms, so every front stem takes -ben.
- Hídhoz: híd is a lexical back-harmony stem.
- Könyvek: the plural uses the noun’s lexical e-linking class.
- Menün: a vowel-final noun takes bare superessive -n.
Common Mistakes
1. Letting an earlier rounded vowel control across final e.
❌ A füzethöz vettem új borítót.
Incorrect — final unrounded e selects -hez.
✅ A füzethez vettem új borítót.
I bought a new cover for the notebook.
2. Creating a rounded form for a two-way suffix.
❌ A kulcs a bőröndbön maradt.
Incorrect — the inessive family has no -bön member.
✅ A kulcs a bőröndben maradt.
The key was left in the suitcase.
3. Treating plural linking vowels as automatic rounding.
❌ A könyvök a felső polcon vannak.
Incorrect — the lexical plural of könyv is könyvek.
✅ A könyvek a felső polcon vannak.
The books are on the top shelf.
4. Ignoring a neutral-vowel stem’s lexical back class.
❌ A hídhez vezető út le van zárva.
Incorrect — híd selects back -hoz.
✅ A hídhoz vezető út le van zárva.
The road leading to the bridge is closed.
Key Takeaways
- Apply rounding only inside a suffix family that has a rounded front member.
- Once the stem is known to be front, its last vowel controls local rounding; suffixes can become the controller for later suffixes.
- Keep lexical backness, vowel-final attachment, and linking-vowel stem class distinct from three-way harmony.
