Three-Form, Two-Form, and Invariable Adjectives

Not every Romanian adjective has four forms. Once you have the four-form class down, the rest of the system is about collapse: adjectives that merge some of those four cells, all the way down to ones that never change at all. This page covers the three reduced classes — three-form (like mare/mari), two-form (like verde/verzi), and invariable (like roz, bej, maro, gri). The practical takeaway is twofold: you need fewer endings than you might fear, and you must resist the urge to force endings onto words that don't take them.

Three-form adjectives: mare / mari

A three-form adjective ends in -e in the singular and -i in the plural, and it makes no gender distinction. The model is mare ("big, large"). Singular mare covers both masculine and feminine; plural mari covers both as well.

Femininemaremari

The name "three-form" is the traditional label, because mare patterns with adjectives that, in the fuller analysis, show three shapes across the paradigm; in practice the everyday lesson is simpler — one singular, one plural, no gender to track.

un oraș mare

a big city (masculine — mare)

o problemă mare

a big problem (feminine — same form, mare)

orașe mari și probleme mari

big cities and big problems (mari for everything plural)

Are niște ochi mari și verzi.

She has big green eyes.

This is a relief after the four-form class: with mare you never have to decide between masculine and feminine. Other common adjectives in this family include tare ("strong/hard/loud"), subțire ("thin"), and iute ("quick/spicy") — all singular in -e, plural in -i, gender-neutral.

💡
For three-form adjectives, the only choice you make is singular or plural. Mare → mari, tare → tari, subțire → subțiri. Ignore gender entirely; it does no work here.

Two-form adjectives: verde / verzi

A large set of adjectives ending in -e distinguish only singular vs plural as well, but get grouped separately because the plural triggers a consonant change. The model is verde ("green") → verzi, where the d → z softening before -i is the same one you saw in noun and four-form plurals (brad → brazi).

SingularPlural
Masculineverdeverzi
Feminineverdeverzi

un măr verde

a green apple (singular)

mere verzi

green apples (verde → verzi: d softens to z)

un vin dulce și niște prăjituri dulci

a sweet wine and some sweet cakes (dulce → dulci)

The same single-axis pattern (singular -e, plural -i with whatever consonant change the stem demands) runs through dulce → dulci ("sweet"), rece → reci ("cold"), proaspăt... (no — that's four-form), tânăr... (four-form too). Stick to the clear cases: verde/verzi, dulce/dulci, rece/reci. Whether grammars call these "two-form" or lump them with mare is a labeling matter; what you need to know is that they ignore gender and only mark number.

Berea e prea rece, iar supa e prea fierbinte.

The beer is too cold, and the soup is too hot.

Invariable adjectives: roz, bej, maro, gri

A small but high-frequency group of adjectives never changes form — same word for masculine, feminine, singular, and plural. Most are loanwords, especially colors borrowed from French, plus a few others. The core list every learner should know:

Invariable adjectiveMeaningOrigin
rozpinkFrench rose
bejbeigeFrench beige
marobrownFrench marron
grigreyFrench gris
bleu(light) blueFrench bleu
kakikhakivia French/English
oranjorange (color)French orange

o rochie roz și două rochii roz

a pink dress and two pink dresses (roz never changes)

un pantof maro, doi pantofi maro

one brown shoe, two brown shoes (maro is fixed)

pereți gri, o mașină gri, niște nori gri

grey walls, a grey car, some grey clouds (gri everywhere)

Și-a cumpărat un palton bej foarte elegant.

She bought herself a very elegant beige coat.

Why don't they inflect? Because they entered Romanian as fixed French words and never acquired the native ending system. Their final sounds (-o in maro, -i in gri, -z in roz) don't fit the inflectional slots, so the language simply leaves them alone. Native colors, by contrast, inflect fully: roșu/roșie/roșii, galben/galbenă/galbeni/galbene, negru/neagră/negri/negre, alb/albă/albi/albe. See color adjectives for the full split between inflecting and invariable colors.

💡
The invariable colors are nearly all French borrowings: roz, bej, maro, gri, bleu, mov, oranj, kaki. If a color word "looks French," assume it does not change. Native Romanian colors (roșu, galben, negru, alb, verde, albastru) inflect normally.

Common Mistakes

The most damaging error is hypercorrection — forcing agreement onto an invariable adjective once you have learned that adjectives "always agree":

❌ o rochie roză

Incorrect — roz is invariable; there is no form 'roză'.

✅ o rochie roz

a pink dress

❌ niște pantofi maroi

Incorrect — maro never takes a plural -i.

✅ niște pantofi maro

some brown shoes

Don't put a gender ending on a three-form adjective — mare has no feminine marea (that spelling means "the sea"!):

❌ o casă mareă

Incorrect — mare is the same for both genders; no feminine ending.

✅ o casă mare

a big house

Do still make number agreement on three- and two-form adjectives — they are invariable for gender, not for number:

❌ mere verde

Incorrect — plural noun needs the plural form verzi.

✅ mere verzi

green apples

Key Takeaways

  • Three-form (mare/mari) and two-form (verde/verzi) adjectives ignore gender and mark only number; the only difference is whether the plural triggers a consonant change.
  • Invariable adjectives — mostly French color loans (roz, bej, maro, gri, bleu, mov) — never change at all.
  • The big A2 trap is hypercorrection: do not invent roză, maroi, mareă. Learn which words are frozen.
  • Reduced-form adjectives are still inflected for number where they can be (verde → verzi); only the truly invariable ones stay fixed in the plural.

  • Color Adjectives and InvariablesA2Native color words agree fully (alb/albă/albi/albe, roșu/roșie/roșii), but borrowed and compound colors (roz, bej, maro, gri, bleu, mov) are completely invariable — so 'pink dresses' is rochii roz, with no agreement.
  • Mistake: Adjective and Article AgreementA2English speakers leave adjectives frozen in the masculine-singular dictionary form (*o casă mic) and double-article fronted adjectives (*frumoasa fata). Two habits fix almost everything: always inflect the adjective to match its noun, and put the definite article on the FIRST element only.
  • Feminine Plurals (-e, -i)A2Feminine plurals are Romanian's trickiest: the ending splits between -e and -i, and a root-vowel shift (a→e in masă→mese, oa→o in poartă→porți, a→ă in carte→cărți) usually fires at the same time. This same plural stem is what the feminine genitive-dative singular is built on.
