Vowel-Dropping and Vowel-Lengthening Stems: Meanings and Usage | Hungarian Grammar

Stem alternation does not add a separate meaning. It supplies the shape required when an ordinary plural, case, or possessive ending is used. Bokor and bokr- both mean “bush,” while alma and lengthened almá- both mean “apple.” What changes is the grammatical environment and, with it, the form that carries the intended discourse role. The forms page presents the paradigms, while the contrast page resolves difficult class boundaries.

Identifying an object

The accusative marks a definite or indefinite direct object. With a vowel-dropping noun, the reduced stem appears before its accusative pattern: bokrot, tükröt, szobrot, dolgot, álmot. Final a/e lengthens: almát, körtét, leckét.

A kertész megmetszette a bokrot a kapu mellett.

The gardener pruned the bush beside the gate.

A tükröt még ma fel kell szerelnünk.

We still need to mount the mirror today.

Vacsora után megcsinálom a leckét.

I'll do my homework after dinner.

English identifies objects mostly through word order. Hungarian marks them morphologically, so the object ending remains necessary when the object moves for focus: A bokrot metszette meg, nem a fát. The stem alternation follows the accusative environment regardless of position.

A bokrot metszette meg, nem a fát.

It was the bush that he pruned, not the tree.

💡

Meaning selects the accusative; the lexicon supplies bokr-; harmony supplies back -ot. Those are three decisions, not one guessed ending.

Talking about more than one

Plural -k also selects the reduced stem of common vowel-dropping nouns: bokrok, tükrök, szobrok, dolgok, álmok, eprek. Final-vowel words attach -k after lengthening: almák, körték, leckék.

A bokrok gyorsan nőnek az eső után.

The bushes grow quickly after the rain.

A múzeum új szobrokat állított ki.

The museum put new sculptures on display.

Az eprek idén különösen édesek.

The strawberries are especially sweet this year.

Hungarian keeps a noun singular after an exact numeral: két alma, not két almák. Stem alternation therefore depends on the form actually required, not on plural meaning in the abstract.

Két almát és három körtét vettem.

I bought two apples and three pears.

Here both nouns are grammatically singular after the numerals but accusative as objects. Their final vowels lengthen because of -t, not because the real-world quantities are plural.

Expressing possession and personal involvement

Hungarian marks the possessed item with a suffix. Vowel-dropping stems normally use the reduced allomorph: bokrom “my bush,” tükröd “your mirror,” álma “his/her dream,” dolgom “my matter/task.” Final a/e lengthens before possessive endings: almám, körtéd, leckéje.

Eltört a tükröm költözés közben.

My mirror broke during the move.

Ma rengeteg dolgom van, ezért később hívlak.

I have loads to do today, so I'll call you later.

Az az álmom, hogy egyszer saját könyvesboltom legyen.

My dream is to have my own bookshop one day.

The last two examples are abstract. Dolgom van is an idiomatic way to say one has business, tasks, or something to do; az az álmom frames a personal aspiration. The reduced forms are just as obligatory here as with concrete tükröm.

A gyerek uzsonnája egy alma és egy szelet kalács.

The child's snack is an apple and a slice of sweet bread.

In uzsonnája, final a of uzsonna becomes á before third-person possessive -ja. Do not confuse this stem vowel with the a inside the suffix.

Location and direction

The contrast between full and reduced stems is especially visible across local cases. Superessive -on/-en/-ön selects the reduced stem in common vowel-dropping nouns: bokron, tükrön, szobron. Consonant-initial -ban/-ben, -hoz/-hez/-höz, -tól/-től normally follow the full stem: bokorban, tükörben, szoborhoz.

Hó maradt a bokron, de a bokorban már madarak mozgolódnak.

Snow remained on the bush, but birds are already stirring inside it.

Egy apró repedést vettem észre a tükrön.

I noticed a tiny crack on the mirror.

A tükörben látszik az egész szoba.

The whole room is visible in the mirror.

Final a/e lengthens before either kind of local suffix: szobában, körtében, almához, leckéről. These forms do not “drop back” to short a/e in casual speech.

A jegyzetek a barna mappában vannak.

The notes are in the brown folder.

A short dialogue

This ordinary (informal) exchange combines object, plural, and possessive meanings.

– Megmostad már az almákat és az epret?

— Have you washed the apples and the strawberries yet?

– Az almákat igen, de az eprem nagy része még a hűtőben van.

— The apples, yes, but most of my strawberries are still in the fridge.

– Akkor kiveszem, és készítek egy gyümölcssalátát.

— Then I'll take them out and make a fruit salad.

Epret and eprem use reduced epr-; hűtőben is an unrelated regular local form. Context decides that eprem means the speaker's batch or supply of strawberries even though its grammatical form is singular possessive.

Formal and informal vocabulary

Stem alternation itself is neutral. Register comes from the chosen word and construction. Kérelem–kérelmet “application/request” is frequent in administrative (formal) prose; dolog–dolgot is a broad everyday (informal/neutral) noun.

A kérelmet elektronikus úton kell benyújtani.

The application must be submitted electronically. (formal)

Elintézek még egy dolgot, aztán indulhatunk.

I'll take care of one more thing, and then we can go. (informal)

Both delete an internal vowel before the accusative: kérelm-et, dolg-ot. A formal setting does not restore kérelemet, and casual speech does not license dologot. Regional or highly colloquial variants may exist for individual lexemes (regional: varies), but learners of modern standard Hungarian should use the dictionary principal parts.

💡

Context changes which word is natural, but it does not turn stem alternation into a style choice. Standard kérelmet and dolgot occur wherever those lexemes occur.

Principal parts in active use

When learning a new alternating noun, record forms that serve different functions: dolog – dolgot – dolgok – dolga and tükör – tükröt – tükrök – tükre. This predicts sentences far better than memorizing the translation alone. For a/e stems, record a suffixed form even though the pattern is productive: lecke – leckét, munka – munkát.

The nearest written vowel is not a safe suffix selector. Tükör is front rounded and gives tükröt; eper is front unrounded and gives epret; bokor is back and gives bokrot. First identify the stored stem and its harmony class, then add the appropriate ending.

Common Mistakes

❌ Megöntöztem a bokorot indulás előtt.

Incorrect: the accusative selects reduced bokr-.

✅ Megöntöztem a bokrot indulás előtt.

I watered the bush before leaving.

❌ A tüköröm leesett a falról.

Incorrect: the possessive uses reduced tükr- plus rounded -öm.

✅ A tükröm leesett a falról.

My mirror fell off the wall.

❌ Két almák maradtak a kosárban.

Incorrect: after an exact numeral, the noun stays singular.

✅ Két alma maradt a kosárban.

Two apples remained in the basket.

❌ Tegnap befejeztem a lecket.

Incorrect: final e lengthens to é before accusative -t.

✅ Tegnap befejeztem a leckét.

I finished the homework yesterday.

❌ Egy repedés van a tükören.

Incorrect: superessive -ön selects both reduced tükr- and front rounding.

✅ Egy repedés van a tükrön.

There is a crack on the mirror.

💡

Do not let English word order or spelling obscure the morphological trigger. Choose the grammatical function first, retrieve the lexeme's principal part, and only then apply harmony and rounding.

Key Takeaways

Objects, plurals, possessives, and some local cases can select a reduced stem such as bokr- or tükr-.
Exact numerals keep the noun singular, but case marking still triggers any required stem change or vowel lengthening.
Final a/e lengthens before suffixes in both ordinary and formal contexts.
Choose the grammatical function first, then retrieve the lexeme's appropriate principal part.
