Mistake: Adjective and Article Agreement

In English an adjective never changes shape: a small house, small houses, the small house — small is small every time. So English speakers learning Romanian do the natural thing and leave the adjective frozen in whatever form they learned it, which is the masculine singular dictionary form: mic, frumos, greu. The result is a steady drip of errors like o casă mic ("a small house") and fete frumoși ("beautiful girls"). A second, sneakier error appears once learners discover the enclitic article: when they front an adjective, they article both words — frumoasa fata — because both "want" to be definite. This page targets those two habits. Fix them and the great majority of your agreement errors disappear at once.

Habit 1: leaving the adjective in the dictionary form

The dictionary lists adjectives in the masculine singular: mic (small), frumos (beautiful), greu (hard/heavy), nou (new). That form is correct only when the noun it describes is masculine and singular. The moment the noun is feminine, plural, or both, the adjective must change. A four-form adjective like mic has mic / mică / mici / mici (masc.sg. / fem.sg. / masc.pl. / fem.pl.); frumos has frumos / frumoasă / frumoși / frumoase.

The reason this matters is that the adjective's ending is the listener's grammatical agreement signal — it confirms which noun the adjective belongs to. A frozen mic on a feminine noun is not just "an accent off"; it sends a contradictory gender signal and instantly marks the speaker as a learner.

Notice that the indefinite article already tells you the gender for free: o signals feminine (o casă, o problemă), un signals masculine/neuter (un băiat, un tren). If you wrote o, the adjective downstream must be feminine. Use the article you already chose as a checkpoint for the adjective that follows.

Three- and two-form adjectives don't excuse you

A minority of adjectives have fewer than four distinct forms, and learners sometimes take that as license to stop inflecting. It is not. Mare ("big") is invariable for gender but still inflects for number: mare (sg.) → mari (pl.). Verde ("green") behaves the same: verde → verzi. So even here, a plural noun forces a change.

For the full system of which adjectives have four, three, or two forms, see four-form agreement and adjectives with fewer forms.

Habit 2: double-articling a fronted adjective

Romanian normally puts the adjective after the noun, and the definite article rides as a suffix on the noun: fata frumoasă ("the beautiful girl" — literally "the-girl beautiful"). The article -a sits on fată → fata, and the adjective frumoasă is bare. So far so good.

But Romanian also lets you front the adjective for emphasis or style: frumoasa fată ("the beautiful girl"). Here is the trap. When you move the adjective to the front, the article moves with the first element — it lands on the adjective (frumoasă → frumoasa) — and the noun is left bare (fată, not fata). The article is a property of the whole noun phrase, and it attaches once, to whatever comes first. English speakers, treating "the" as belonging to the noun, leave it on the noun and add it to the fronted adjective, producing two articles.

So the same phrase has exactly one article, and its position depends on word order:

The fronted version (frumoasa fată, marele scriitor) carries a slightly elevated, emphatic, or literary flavor — it foregrounds the quality. The default postnominal order (fata frumoasă) is the everyday choice. Full treatment of the article jumping onto the adjective is on the article on adjectives page.

Agreement also follows case, not just gender and number

One more layer: the adjective must match the noun's case too. In the genitive-dative, a definite fronted adjective takes the gen-dat article ending, and a postnominal adjective agrees with the gen-dat form of the noun. This trips up learners who get gender and number right but forget the noun is in the genitive.

Coordinated nouns: agree with the whole group

When one adjective describes two coordinated nouns of mixed gender, Romanian defaults to the masculine plural (the "stronger" gender wins). Learners often agree only with the nearest noun.

Key Takeaways

• There is no neutral adjective form — the masculine singular is just one of four; always inflect to match the noun's gender, number, and case.
• Use the article you already chose (un vs o) as a built-in checkpoint for the adjective downstream.
• Even "invariable" adjectives like mare and verde still inflect for number (mari, verzi).
• The definite article attaches to the first element of the noun phrase only: fata frumoasă (article on noun) or frumoasa fată (article on fronted adjective) — never both.
• The fronted-adjective order is emphatic/literary; the postnominal order is the everyday default.
