Three-way harmony appears when a suffix distinguishes back, front unrounded, and front rounded stems. The allative family -hoz/-hez/-höz and the superessive family -on/-en/-ön are central examples. Their meanings are broad, but their vowel choice follows the Hungarian stem rather than an English preposition.
Rounding is only one layer. First establish whether the stem is back or front; then, for a suffix that has three forms, use the last relevant front vowel to choose unrounded e or rounded ö. Linking vowels and lexical exceptions can complicate other paradigms. See the companion forms page for the compact architecture.
Approaching people, places, and objects
The allative generally marks movement toward a target or arrival at someone’s place. Back orvos selects orvoshoz, front unrounded ügyvéd selects ügyvédhez, and front rounded főnök selects főnökhöz.
Reggel a fogorvoshoz megyek, délután pedig az ügyvédhez.
I’m going to the dentist in the morning and to the lawyer in the afternoon.
Vidd oda ezt a levelet a főnökhöz, kérlek!
Please take this letter over to the boss.
A gyerek odaszaladt az édesanyjához, majd együtt odamentek a bölcsőhöz.
The child ran over to his mother, and then they went to the cradle together.
English uses to in all three sentences, but English contributes no backness or rounding information. The relevant Hungarian target does: final back o in orvos, final unrounded é in ügyvéd, and final rounded ö in főnök. In édesanyjához, the possessive form before the case ending ends in back á, so the full stem at the point of suffixation selects -hoz.
Connecting ideas and abstract targets
The allative is also used with abstract nouns in expressions meaning “add to,” “relate to,” “adapt to,” or “connect with.” Rounding still follows form, not concreteness. Javaslat is back, while kérdés and helyzet end in front unrounded vowels.
A javaslathoz két rövid megjegyzést fűztem.
I added two brief comments to the proposal.
A kérdéshez több történelmi forrást is találtunk.
We found several historical sources relevant to the question.
Nehéz alkalmazkodni egy folyton változó helyzethez.
It is difficult to adapt to a constantly changing situation.
An earlier rounded vowel does not necessarily control. Örökség contains ö, but the derivational ending -ség places unrounded é closest to the allative, so the form is örökséghez, not örökséghöz.
Az örökséghez régi családi levelek is tartoztak.
Old family letters were also part of the inheritance.
This local behavior is an important difference from front–back harmony, where neutral vowels can sometimes be transparent to an earlier vowel.
Surfaces, locations, and events
The superessive -on/-en/-ön covers literal surfaces, certain locations, institutions, and events. Its English translation may be “on,” “at,” or “in.” Back asztal gives asztalon, front unrounded egyetem gives egyetemen, and front rounded föld gives földön.
A tányér az asztalon, a kabát a széken, a táska pedig a földön van.
The plate is on the table, the coat is on the chair, and the bag is on the floor.
Az egyetemen ismertem meg a páromat, egy nyelvészeti előadáson.
I met my partner at university, at a linguistics lecture.
A koncerten háromszor is visszatapsolták az együttest.
At the concert, the audience called the band back on stage three times.
Choosing the case is semantic and lexical: Hungarian conventionally says egyetemen and koncerten. Once the superessive is selected, harmony shapes the visible ending. An English speaker cannot translate at mechanically into one fixed Hungarian string.
Frequency and repetition
The multiplicative suffix -szor/-szer/-ször says how many times something happens. Numerals themselves determine the member: háromszor “three times,” kétszer “twice,” ötször “five times.”
Háromszor hívtam, kétszer írtam, és ötször ellenőriztem a címet.
I called three times, wrote twice, and checked the address five times.
Here the suffix has the same function throughout, while the numeral changes its form. The vowel in -szor/-szer/-ször is always short. Do not confuse rounding with vowel length: ötször requires both short ö vowels.
Vowel-final stems conceal the three-way vowel
With many vowel-final nouns, the superessive appears simply as -n: autón, kávén, tetőn, menün. The ending still expresses the same case, but there is no inserted o/e/ö to choose. Final short a/e lengthens before it: utca → utcán, lecke → leckén.
A menün már az új ár szerepel, a számlán viszont még a régi összeg van.
The menu already shows the new price, but the bill still has the old amount.
The sentence has menün and számlán: bare -n after final ü, and lengthened á from final a in számla.
Rounding is restricted to listed suffix families
Front rounded vowels do not create ö in every ending. Compare three-way főnökhöz and földön with two-way főnöknek and földben. The dative has only -nak/-nek; the inessive has only -ban/-ben.
A főnöknek szóltam, hogy a kulcsot a földben találták.
I told the boss that the key had been found in the ground.
This restriction must be stored with the suffix. “Round the suffix after ö” is not a Hungarian rule; “choose -höz within the three-member allative family” is.
Stem classes limit apparent rounding patterns
Plural and accusative forms often contain linking vowels that resemble harmonic suffix vowels, but their choice can be lexically conditioned. Compare regular-looking őrök “guards” with könyvek “books” and földek “lands.” Both könyv and föld contain front rounded vowels, yet they take linking e in the plural.
Az őrök a könyveket a felső polcon találták.
The guards found the books on the upper shelf.
This does not make könyv unrounded: the allative remains könyvhöz, and the superessive is könyvön. It means that plural linking vowels belong to morphological stem classes as well as the harmonic system. Learn könyv – könyvek – könyvhöz as a small paradigm.
All-neutral stems can also have a lexical back-harmony class. Híd contains only í but gives hídhoz and hídon. Backness must be settled before the rounding layer can operate.
A hídon várunk, aztán együtt sétálunk a kikötőhöz.
We’ll wait on the bridge and then walk to the harbor together.
A short workplace dialogue
This exchange is (informal) workplace speech. Each target determines a different member of a three-way family.
– Kihez mész ebéd után?
‘Who are you going to see after lunch?’
– Először az ügyvédhez, aztán a főnökünkhöz.
‘First the lawyer, then our boss.’
– A délutáni megbeszélésen is ott leszel?
‘Will you also be at the afternoon meeting?’
The possessive suffix in főnökünk has rounded ü as its final vowel, so the next suffix is -höz: főnök-ünk-höz. The visible sequence of morphemes matters more than the first vowel of főnök.
Formal and informal comparison
Three-way harmony does not change with register. Compare an administrative sentence (formal) with a message between friends (informal):
A kérelmet továbbítottuk az illetékes felügyelőhöz.
We have forwarded the application to the responsible supervisor.
Átugrom a szomszédhoz, utána találkozunk a téren.
I’ll pop over to the neighbor’s, then we’ll meet in the square.
Formal felügyelőhöz takes rounded -höz after final ő. Informal szomszédhoz is back harmonic despite final neutral é, while téren is front unrounded. The vocabulary and sentence style signal register; the harmony system remains the same.
Common Mistakes
1. Ignoring the rounded form of the allative.
❌ Délután a főnökhez megyek.
Incorrect — final rounded ö selects -höz.
✅ Délután a főnökhöz megyek.
I’m going to see the boss this afternoon.
2. Rounding according to the first rather than the last front vowel.
❌ Ceruzát kértem a füzethöz.
Incorrect — final unrounded e in füzet selects -hez.
✅ Ceruzát kértem a füzethez.
I asked for a pencil to go with the notebook.
3. Inventing a rounded member for a two-way family.
❌ A pénzt a bőröndbön találtam.
Incorrect — the inessive has only -ban/-ben.
✅ A pénzt a bőröndben találtam.
I found the money in the suitcase.
4. Predicting a linking vowel as though it were the allative.
❌ Az új könyvök már a polcon vannak.
Incorrect — könyv has the lexical plural könyvek.
✅ Az új könyvek már a polcon vannak.
The new books are already on the shelf.
Key Takeaways
- Use three-way harmony for the suffix families that license it: back o, front unrounded e, and front rounded ö.
- Let the current stem and the last relevant front vowel control local rounding, including across suffix chains.
- Keep semantic case choice, front–back class, rounding, vowel-final attachment, and lexical linking-vowel class as separate decisions.
