Major Noun Stem Classes: Forms and Core Pattern

Hungarian nouns do not decline by grammatical gender, but they do differ in the stem shape and linking vowel used before certain suffixes. The main classes are regular, lowering, vowel-dropping, final-vowel lengthening, vowel-shortening, and v-stems. These are morphophonological classes: they tell you how a word is built, not whether its referent is masculine, feminine, or neuter.

A compact map of the classes

The four columns function as principal parts. If you know only bokor, you may wrongly invent bokorot; bokrot reveals reduced bokr-. If you know only ló, neither the v nor the short o of lovat is predictable.

Regular stems and linking vowels

A regular noun keeps the same lexical stem: asztal- in asztalt, asztalok, asztalom, asztalban; kert- in kertet, kertek, kertem, kertben. The suffix may still have a linking vowel, and harmony chooses its broad class.

Back asztal uses o in asztalok, asztalom. Front unrounded kert uses e in kertek, kertem. Front rounded sör uses ö in sörök, söröm, although its accusative is direct sört. The suffix family and phonological environment determine whether a linking vowel appears.

This stable-stem pattern is the productive default for new nouns, but the exact linking vowel cannot always be improvised. Learn at least an accusative or plural with the headword.

Lowering stems

Lowering nouns use a or e where a regular pattern may suggest o or rounded ö. Back ház gives házat, házak, házam; láb gives lábat, lábak, lábam. Front rounded fül gives unrounded fület, fülek, fülem; föld gives földet, földek, földem.

Harmony says back or front; lowering class makes the further a/e choice. The final vowel written in the stem is not a reliable shortcut: both sör and föld contain ö, but the plurals are sörök and földek.

Vowel-dropping stems

Words such as bokor, tükör, dolog, álom, eper, szobor, and torok have a full free form and a reduced bound allomorph: bokor ~ bokr-, tükör ~ tükr-, dolog ~ dolg-. The reduced form appears in common accusatives, plurals, possessives, and superessives: bokrot, bokrok, bokrom, bokron.

Consonant-initial cases generally keep the full stem: bokorban, bokornak, bokorhoz. Similar-looking words need not drop a vowel: motor–motort–motorok is stable.

The class is lexical rather than fully predictable from permissible consonant clusters. Review vowel-dropping forms for the environment details.

Final a/e lengthening

Short final a and e normally become long á and é before ordinary inflectional suffixes: alma–almát–almák–almám, körte–körtét–körték–körtém, szoba–szobában, lecke–leckéről. The long accent represents pronunciation and must be written.

This is the most productive nondefault pattern on the page. It is not a command to lengthen before every derivational continuation: adjective-forming -i gives szobai and megyei, with short a/e, and almafa preserves alma inside a compound. Do not confuse lengthening with stems whose dictionary form already ends in a long vowel: kávé–kávét, autó–autót simply retain é/ó.

Vowel-shortening stems

Some nouns shorten a long vowel in principal parts such as accusative, plural, and possessive: kéz–kezet–kezek–kezem, víz–vizet–vizek–vizem, út–utat–utak–utam, kenyér–kenyeret–kenyerek–kenyerem, madár–madarat–madarak–madaram.

Other suffixes may select the full stem: kézben, vízben, úton, kenyérben, madáron. Therefore “shorten before every suffix” is not a valid rule.

Notice the short u in utat but long ú in úton. The suffix distribution belongs to each stem family.

v-stems

V-stems pair a free long-vowel form with a shorter allomorph containing v: ló–lov-, kő–köv-, tó–tav-, fű–füv-, lé–lev-, and szó–szav-. Common forms include lovat, lovak, lovam, lovon and követ, kövek, kövem, kövön.

The distribution varies by word. Szó keeps the full form in szót and szón, but uses szav- in szavak, szavam. Consonant-initial cases commonly retain the long form: lónak, kőhöz, szótól.

What dictionaries and notes should record

For a noun that may alternate, record nominative – accusative – third-person possessive – plural, for example bokor – bokrot – bokra – bokrok and ló – lovat – lova – lovak. A first-person possessive, bokrom/lovam, is also useful. These forms expose deletion, linking-vowel class, j-selection in possession, shortening, and v-extension.

There is no honest rule that predicts every class from spelling. Regular stems and final a/e lengthening are productive; lowering, dropping, shortening, and v-stem membership contain lexical information. A dictionary check is normal, not a failure of analysis.

Segmentation exercise

1. asztalok = stable asztal- + -ok.
2. házak = lowering ház- + -ak.
3. bokrot = reduced bokr- + -ot.
4. almát = lengthened almá- + -t.
5. kezet = shortened kez- + -et.
6. lovak = v-stem lov- + -ak.
7. szót = full szó- + -t, despite plural szavak.

Common Mistakes

Key Takeaways

Hungarian noun classes describe form, not gender. Stable stems keep their shape; lowering stems choose a/e linkers; vowel-dropping stems use a reduced allomorph; final a/e lengthens productively; shortening stems reduce a long vowel in selected forms; and v-stems add v while changing the vowel. Principal parts are the dependable bridge from a dictionary form to natural inflection.
