Attributive Invariability and Predicative Plural Agreement: Forms and Core Pattern

Hungarian adjectives behave differently depending on their job. Before a noun, an adjective is invariant: szép ház, szép házak, szép házban. As a predicate describing a plural subject, it receives plural marking: A házak szépek “The houses are beautiful.”

This page establishes that formal contrast, including the zero third-person copula and adjectives used as nouns. Broader contexts appear on the usage page, and difficult boundary cases on the contrast page. Unlabeled forms are neutral modern standard Hungarian.

Before a noun: one unchanged adjective

An attributive adjective stands immediately before the noun it modifies and does not copy the noun's number or case. The noun carries the relevant ending.

Régi does not receive plural -k or accusative -t; both appear on könyveket. Csendes does not take inessive -ban; utcában does. This “mark the noun once” pattern applies to every ordinary prenominal adjective, including several in a row.

After the numeral két, the noun remains singular in Hungarian: két szoba, here accusative két szobát. The adjectives remain unchanged too. English speakers already know invariant adjectives, but endings elsewhere in Hungarian can tempt them to mark every word in the phrase; Hungarian does not do that.

Predicate position: plural adjectives agree

When an adjective is the predicate—not inside the noun phrase—it carries plural marking for an overtly plural-marked subject.

In világosak, the adjective is separate from a szobák and receives plural -k with linking vowel a. In kényelmesek, front-vowel e appears. The common plural surfaces as -ak/-ek, but other stem classes produce -ok/-ök or attach -k directly.

Nagy → nagyok has -ok. Nehéz → nehezek uses the alternate stem nehez-. Vowel harmony constrains the linking vowel, but adjective stem class must sometimes be learned lexically.

Quantified subjects remain grammatically singular

A numeral or quantity expression keeps its noun morphologically singular. The predicative adjective therefore stays singular too, even when the phrase refers to several entities.

Compare plural-marked A szobák világosak with quantified A két szoba világos. Hungarian agreement follows the visible grammatical number of the subject phrase rather than real-world plurality alone.

The zero third-person copula

In present indicative third person, a nominal or adjectival predicate has no overt form of van. This is true in both singular and plural.

English requires “is/are,” but Hungarian expresses third-person present tense through the construction itself. The plural adjective still agrees: forrók. Do not add vannak merely because the subject is plural.

Outside present third person, the copula is visible. Plural adjective agreement remains:

In fáradtak voltak, both the predicate adjective and past copula show plurality. With first-person mi, present vagyunk is overt, and fáradtak agrees with the plural subject.

Building predicative plurals

The adjective's plural generally matches its ordinary substantivized plural. Several common classes are worth memorizing.

Not every final vowel takes direct -k: hosszúak, könnyűek retain their long vowels and add a linking vowel. Jók is shorter. These are normal inflectional classes, not register variants.

Coordinated predicate adjectives each agree when plural: rövidek and pontosak. A shared plural ending cannot be placed only on the last adjective.

Substantivized adjectives

An adjective can stand for a person or thing when the category is clear. It then behaves like a noun: it can take the definite article, plural -k, and case endings.

In piros-at and kék-et, accusative marks the omitted object. In a nagyok, plural -ok refers to identified large items. Articleless kicsik introduces or describes the remaining small ones as an indefinite set.

Adjectives can also name groups of people: a fiatalok “young people,” az idősek “older people,” a gazdagok “the rich.” This use is neutral, though the social effect of labeling people by one property depends on context.

Once substantivized, the adjective itself is the head, so it carries both plural and case:

Friss-ek-ből means “from among the fresh ones.” Contrast attributive friss almákból, where only almákból carries plural and elative marking.

Comparative adjectives obey the same structural split

Comparative -bb does not change the agreement rule. Before a noun it stays invariant; as a plural predicate it takes plural marking.

English uses separate “more” with many adjectives, but Hungarian generally forms the comparative with -bb. Do not translate “larger” as több nagy: több nagy doboz means “more large boxes,” not “larger boxes.” The full system appears on the comparison forms page.

Segmentation exercise

1. szép házakban → szép + ház-ak-ban: the attributive adjective is unchanged; the noun carries plural and inessive.
2. szépek → szép-ek: plural predicative or substantivized adjective.
3. nagyokat → nagy-ok-at: adjective used as a noun + plural + accusative.
4. könnyűek → könnyű-ek: long ű remains, followed by the plural linker and k.
5. nehezek → nehez-ek: the adjective uses its alternate stem before plural.
6. nagyobbak → nagy-obb-ak: comparative + plural predicate.

Common Mistakes

Key Takeaways

• Before a noun, an adjective is invariant; number and case appear on the head noun.
• As a predicate of an overtly plural-marked subject, the adjective takes plural marking: szépek, nagyok, kényelmesek.
• A numeral keeps both its noun and predicative adjective singular: A két szoba világos.
• Present third-person adjectival predicates omit van/vannak, but agreement remains visible.
• A substantivized adjective becomes the head and can carry plural and case: a pirosat, a nagyok, a frissekből.
• Comparative adjectives follow the same split: nagyobb dobozok but a dobozok nagyobbak.
