The shortest reliable contrast is a drága autók “the expensive cars” versus Az autók drágák “The cars are expensive.” The adjective is unchanged when it helps build a noun phrase, but plural when it is the property asserted of a plural subject. Physical position is a useful clue, not the rule: Hungarian can move a predicate for focus, and an adjective can stand alone as a noun.
Modifier versus predicate
In an attributive phrase, the noun carries plural and case morphology. In a predicative clause, both the plural subject and the adjective display number.
| Function | Hungarian | What carries plural? |
|---|---|---|
| attributive | a csendes szobák | szobák only |
| predicative | A szobák csendesek. | szobák and csendesek |
| substantivized | a csendesek | the adjective replacing a noun |
A keskeny utcák csendesek éjszaka.
The narrow streets are quiet at night.
Keskeny is inside the subject phrase and remains unchanged. Csendesek makes the new assertion and is plural. Adding more modifiers changes nothing: a régi, keskeny, macskaköves utcák puts all endings on utcák.
CSENDESEK ezek az utcák, de nem biztonságosak.
These streets are QUIET, but they are not safe.
Fronting csendesek for contrast does not turn it into an attributive adjective. It remains plural because it is still the predicate. Capitalization here represents spoken emphasis; ordinary spelling uses lowercase.
Zero copula versus an expressed form of be
Present-tense third-person adjectival predicates omit van/vannak:
A boltok nyitva vannak, de az éttermek még zárva vannak.
The shops are open, but the restaurants are still closed.
This example deliberately uses nyitva/zárva, adverbial participial state forms, which occur with vannak. With plain adjectives, say:
A boltok zsúfoltak, de az éttermek még üresek.
The shops are crowded, but the restaurants are still empty.
Do not say a boltok vannak zsúfoltak. The distinction is lexical and structural: plain zsúfolt forms an adjectival predicate, while nyitva is a -va/-ve state form that normally combines with van. Location likewise requires van/vannak: A vendégek bent vannak, “The guests are inside.”
With first and second person, the copula is visible: Én fáradt vagyok, Ti fáradtak vagytok. It also appears in the past or future: A boltok zsúfoltak voltak, A boltok zsúfoltak lesznek.
Tegnap fáradtak voltunk, ma viszont energikusak vagyunk.
Yesterday we were tired, but today we are energetic.
Both adjectives agree with first-person plural we, and the copula separately shows person, number, and tense.
Overt plural versus quantified singular
Hungarian number marking after numerals and quantity expressions differs from English. An overt plural subject selects a plural predicate; a singular-form quantified subject selects a singular predicate.
A diákok fáradtak, de sok diák még mindig figyelmes.
The students are tired, but many students are still attentive.
Mindkét válasz helyes, de a válaszok nem egyformán részletesek.
Both answers are correct, but the answers are not equally detailed.
Diákok and válaszok are morphologically plural, so fáradtak and részletesek are plural. Sok diák and mindkét válasz have singular nouns, so figyelmes and helyes are singular. Agreement tracks the form licensed by Hungarian grammar, not the number of individuals in the English translation.
Coordinated singular noun phrases behave differently from a quantified singular phrase:
Péter és Anna fáradtak, de a két gyerek energikus.
Péter and Anna are tired, but the two children are energetic.
With two named people before the predicate, plural fáradtak is the natural neutral choice. Coordinated singular subjects do permit agreement variation in some configurations, especially with inanimate or postposed conjuncts, so coordination is not identical to an overt -k plural. The quantified a két gyerek, however, systematically remains grammatically singular and selects energikus.
Adjective plus omitted noun versus adjective plus noun
An adjective before an overt noun remains invariant; one replacing a noun takes number and case. This produces minimal pairs that English distinguishes with one/ones:
A piros almákat kérem, nem a zöldeket.
I'd like the red apples, not the green ones.
Piros modifies overt almákat and has no ending. Zöldeket replaces almákat, so it takes plural -ek plus accusative -et. If only one apple were meant, the form would be a zöldet.
Az új dolgozók segítenek a régieknek.
The new employees are helping the old ones.
Attributive új stays unchanged before dolgozók. Substantivized régieknek bears plural and dative endings. Human readings such as a fiatalok “young people” and az idősek “elderly people” are established and occur across registers. With other adjectives, a missing noun needs a clear context.
Adjective versus adverb
Plural -k belongs on an adjective that predicates a property of plural subjects. If a word instead describes how an action happens, Hungarian normally uses an adverb such as gyorsan, not a plural adjective.
A gyors vonatok pontosak, és általában gyorsan közlekednek.
The fast trains are punctual and generally travel quickly.
Gyors is invariant before vonatok; pontosak is a plural predicate; gyorsan modifies közlekednek. English uses fast as both adjective and adverb, which encourages the wrong Hungarian form.
A gyerekek most csendesek, és csendesen játszanak.
The children are quiet now and are playing quietly.
The difference is semantic: csendesek attributes quietness to the children, whereas csendesen characterizes their manner of playing.
Comparative adjectives keep the same contrast
A comparative remains invariant before a plural noun but agrees when predicative:
Olcsóbb jegyeket találtunk, de ezek a jegyek még mindig drágábbak a tavalyiaknál.
We found cheaper tickets, but these tickets are still more expensive than last year's.
Olcsóbb is attributive before accusative plural jegyeket. Drágábbak agrees with plural jegyek. The comparative standard a tavalyiaknál is a substantivized plural adjective meaning “than last year's ones.”
English more interesting books has an additional trap. Hungarian érdekesebb könyvek means “more interesting books” by degree, while több érdekes könyv means “more interesting books” by quantity—that is, a larger number of books that are interesting. The comparison contrasts develops this ambiguity.
Information structure and register
Word order can foreground the predicate without altering agreement: Nagyon drágák lettek a lakások “The apartments have become very expensive.” This is common in conversation and journalism. In (academic) prose, predicative plural agreement remains the same even in dense coordination: A feltételek szükségesek, de önmagukban nem elégségesek. “The conditions are necessary but not sufficient by themselves.”
Substantivized labels for people deserve pragmatic care. A munkanélküliek “the unemployed” and az idősek “older people” are established neutral collective terms, but reducing people to an adjective can sound impersonal in sensitive contexts. This is a discourse consideration, not a change in morphology.
Az idősek számára az alacsony padlós buszok kényelmesebbek.
Low-floor buses are more convenient for older people.
Decision tree
- Does an overt noun immediately follow as the head? Leave the adjective unchanged: szép házak, szép házakban.
- Is the adjective asserting a property of the subject? Make it plural if the Hungarian subject is morphologically plural: A házak szépek. With coordinated singular subjects, neutral preverbal coordination—especially of people—usually favors plural agreement, while other word orders and inanimate coordinations can vary.
- Is the subject headed by két, sok, minden, mindkét or a similar quantifier and therefore singular in form? Use a singular predicate: Sok ház szép.
- Is the adjective replacing an understood noun? Give it the noun's plural and case endings: a szépeket.
- Does the expression describe an action's manner? Choose an adverb: szépen énekelnek.
Diagnostic exercise
Choose the standard form: (1) a magas / magasak fák; (2) A fák magas / magasak; (3) A három fa magas / magasak; (4) “I see the tall ones,” Látom a magas / magasakat. The answers are (1) a magas fák, because the adjective is attributive; (2) A fák magasak, because it is predicative with a plural subject; (3) A három fa magas, because the numeral licenses singular fa; and (4) Látom a magasakat, because the adjective replaces a plural object.
Common Mistakes
❌ a régiek épületek
Incorrect — régiek cannot agree before an overt plural noun.
✅ a régi épületek
the old buildings
❌ Az épületek régi.
Incorrect — a predicative adjective agrees with the plural subject.
✅ Az épületek régiek.
The buildings are old.
❌ Sok épület régiek.
Incorrect — after sok, the noun and predicate are grammatically singular.
✅ Sok épület régi.
Many buildings are old.
❌ A buszok vannak lassúak.
Incorrect — a present third-person adjectival predicate omits vannak.
✅ A buszok lassúak.
The buses are slow.
❌ Ezek a könyvek több érdekesek.
Incorrect — több expresses quantity, not a higher degree of an adjective.
✅ Ezek a könyvek érdekesebbek.
These books are more interesting.
Key Takeaways
- A csendes szobák has an invariant modifier; A szobák csendesek has a plural predicate.
