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 mic/mică/mici, which still splits gender in the singular but merges its two plurals), two-form (like mare/mari and verde/verzi, which drop gender altogether), and invariable (like roz, bej, maro, gri, which never change). 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: mic / mică / mici

A three-form adjective still marks gender in the singular — exactly like the four-form class — but its two plurals fall together into one form. That leaves three distinct shapes instead of four. The model is mic ("small").

SingularPlural
Masculinemicmici
Femininemicămici

In the singular, mic behaves just like bun: masculine mic, feminine mică. The genders part company only there; in the plural they share a single mici. So the full set is mic / mică / mici — three forms, not four.

un copil mic și o fetiță mică

a small child and a small little girl (mic vs mică — gender still splits in the singular)

copii mici și fetițe mici

small children and small little girls (mici covers both genders in the plural)

Many everyday adjectives work this way — the singular keeps a masculine/feminine contrast, the plural merges. Other common three-form adjectives include nou ("new" → nou / nouă / noi), lung ("long" → lung / lungă / lungi), and the native color roșu ("red" → roșu / roșie / roșii).

💡
The test for three-form vs two-form is the singular. If the adjective still changes for gender there (mic → mică), it is three-form. If the singular is a single shape for both genders (mare, verde), it is two-form.

Two-form adjectives: mare / mari and verde / verzi

A two-form adjective drops gender entirely: one singular for both masculine and feminine, one plural for both. The only choice you ever make is singular vs plural. These adjectives nearly all end in -e in the singular and -i in the plural. The prototype is mare ("big, large").

Femininemaremari

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)

The one thing that varies inside this class is whether the plural -i disturbs the stem. Mare takes it cleanly (mare → mari). Verde ("green"), by contrast, softens its d → z before the -i — the same alternation you meet in noun and four-form plurals (brad → brazi) — giving verde → verzi. Both are equally two-form; the consonant change is a spelling detail, not an extra form.

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)

Other members of the class: tare ("strong/hard/loud"), subțire ("thin"), iute ("quick/spicy"), dulce → dulci ("sweet"), rece → reci ("cold") — all one singular, one plural, no gender to track.

Berea e prea rece, iar supa e prea fierbinte.

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

Are niște ochi mari și verzi.

She has big green eyes. (mari and verzi — both plural, no gender)

💡
For two-form adjectives, the only choice you make is singular or plural. Mare → mari, verde → verzi, dulce → dulci. Ignore gender entirely; it does no work here.

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
movpurple/mauveFrench mauve

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 two-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 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

  • A three-form adjective (mic / mică / mici) still marks gender in the singular but merges its two plurals; a two-form adjective (mare/mari, verde/verzi) ignores gender completely and marks only number.
  • 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.
