A linking vowel appears between a stem and an ending in forms such as asztal-ok, ház-ak, kert-ek, and sör-ök. It supplies the conventional shape of that morphological boundary, but it is not freely inserted wherever a consonant cluster feels difficult. Harmony narrows the possibilities; the particular suffix and the noun or verb's lexical stem class determine the result. See the forms page for full patterns and the usage page for their functions.
Harmony does not make the whole decision
Backness gives a first division: back stems cannot normally take a front linking vowel, and front stems cannot normally take a back one. Yet that does not tell you whether a back stem needs o or lowering a, or whether a front rounded stem uses ö or unrounded e.
| Stem | Plural | What the pair shows |
|---|---|---|
| asztal | asztalok | Regular back linking o |
| ház | házak | Lowering back linking a |
| sör | sörök | Front rounded linking ö |
| föld | földek | Lowering/front unrounded linking e |
The matched pairs asztalok–házak and sörök–földek prove that the nearest stem vowel is not enough. Both members of the first pair are back; both members of the second contain front rounded vowels. Their different linking vowels are lexical properties of the stems.
Az asztalok már a teremben vannak.
The tables are already in the hall.
A régi házak között van egy kis pékség.
There is a small bakery among the old houses.
Kétféle kézműves sört kóstoltunk.
We tasted two kinds of craft beer.
A környező földeket tavasszal vetik be.
The surrounding fields are sown in spring.
One stem, several suffix environments
The plural -k, accusative -t, possessive endings, and verbal personal endings do not all have an identical linking-vowel paradigm. Compare asztalok “tables,” asztalt “table” as an object, and asztalom “my table.” The accusative is direct because -lt is licensed here, while the plural and first-person possessive contain o. A learner cannot take asztalok and mechanically remove k to predict every form.
Tegnap vettem egy asztalt.
I bought a table yesterday.
Az asztalom túl nagy ehhez a konyhához.
My table is too large for this kitchen.
Lowering stems show a stronger family resemblance: házak, házat, házam all have a. Front rounded fül similarly gives fülek, fület, fülem, not forms with ö. This recurring low vowel is why the class is called “lowering.” Even here, the alternation belongs to particular suffixes; consonant-initial -ban/-ben gives házban, without a linking vowel.
A házban három szoba van, de a házam még felújításra szorul.
The house has three rooms, but my house still needs renovating.
Fáj a fülem, ezért ma inkább otthon maradok.
My ear hurts, so I'd rather stay home today.
Verbs have their own patterns. The indefinite first-person singular often shows -ok/-ek/-ök: várok, kérek, ülök. Definite forms similarly include várom, kérem, őrzöm. These verbal endings participate in harmony and rounding, but noun-specific “lowering” cannot simply be transferred to a verb with a similar-looking stem.
Kint várok, amíg befejezed a megbeszélést.
I'll wait outside until you finish the meeting.
Kérem a számlát, ha lehet.
I'd like the bill, please.
Linking vowel or part of a changing stem?
Surface spelling can hide the boundary. In bokrok, the nominative bokor has lost its second o, and plural -ok follows the reduced stem: bokr-ok. Treating the visible o as merely “the vowel from bokor” gives the wrong analysis and makes related bokrot, bokrom, bokron harder to learn. This is stem allomorphy plus a linking vowel.
A bokrok mögött találtuk meg a labdát.
We found the ball behind the bushes.
By contrast, motorok keeps the complete stem motor and adds -ok: motor-ok. Similar-looking nominatives can therefore behave differently.
A motorok egész éjjel az udvaron álltak.
The motorbikes stood in the courtyard all night.
The same warning applies to short-vowel stems such as kéz–kezek and v-stems such as kő–kövek. The e or ö visible before -k is not always just a freely chosen buffer. Record principal parts and segment them morphologically.
Meaning, focus, and register
Information structure does not select the linking vowel. Strongly contrasting házak with asztalok changes stress and word order, but their lexical forms remain intact.
Nem az asztalok újak, hanem a székek.
It isn't the tables that are new, but the chairs.
Standard linking vowels are not formal-versus-informal alternatives. Házok is not the ordinary plural in modern standard Hungarian; the required form is házak. Conversely, a speaker cannot make asztalak more formal than asztalok. In (formal) and (academic) prose, the standard lexical form is expected; ordinary (informal) conversation uses the same form.
Decision tree
- Which suffix is being added? Plural, accusative, possessive, and verbal endings have related but nonidentical patterns.
- Does the form take a linking vowel at all? Learn forms such as asztalt and sört with direct -t.
- Is the stem back or front? This excludes the wrong harmony class.
- If front, does this suffix family allow rounded ö? Compare sörök with kertek.
- Is the noun a lowering stem? Use its principal parts: ház–házat–házak, fül–fület–fülek.
- Does the stem itself alternate? Analyze bokr-ok, not a fictitious unchanged bokorok.
- Is the form unfamiliar or variable? Check a dictionary; phonotactic intuition alone does not reliably predict lexical class.
Diagnostic exercise
Choose the standard form.
- “houses”: házok / házak
- “beers”: sörek / sörök
- “fields”: földök / földek
- “bushes”: bokorok / bokrok
- “the table” as an object: asztalot / asztalt
Answers: (1) házak because ház is a back lowering stem. (2) sörök because this plural keeps front rounding. (3) földek because föld belongs to the class using unrounded e here despite its rounded stem vowel. (4) bokrok combines reduced bokr- with plural -ok. (5) asztalt takes accusative -t directly; its plural asztalok does not predict an accusative asztalot.
Common Mistakes
❌ A hegyoldalban új házok épülnek.
Incorrect in modern standard Hungarian: ház is a lowering stem.
✅ A hegyoldalban új házak épülnek.
New houses are being built on the hillside.
❌ Két hideg söret kérek.
Incorrect: the rounded-front noun sör takes the accusative directly here.
✅ Két hideg sört kérek.
I'd like two cold beers.
❌ Ősszel felszántják a földöket.
Incorrect: föld uses the unrounded linking vowel e in its plural and plural accusative.
✅ Ősszel felszántják a földeket.
They plow the fields in autumn.
❌ Megmetszettük a bokorokat.
Incorrect: bokor uses the reduced stem bokr- before the plural ending.
✅ Megmetszettük a bokrokat.
We pruned the bushes.
❌ Ezt az asztalot tegnap hozták.
Incorrect: asztal takes accusative -t directly.
✅ Ezt az asztalt tegnap hozták.
This table was delivered yesterday.
Key Takeaways
- Harmony narrows the linking-vowel choices, but the suffix family and the stem's lexical class finish the selection.
- Plural, accusative, and possessive forms can use different linking patterns even with the same stem.
- Separate a true linking vowel from a vowel that belongs to a changing stem allomorph.
- Learn principal parts for lowering and otherwise irregular nouns instead of predicting them from spelling alone.
