Determiner Agreement: Master Summary | Romanian Grammar

This page pulls every Romanian determiner into one place so you can see the shared machinery. The headline, repeated from the determiners overview but now made concrete in a single grid, is this: every Romanian determiner inflects for gender and number, and the ones that sit before the noun also inflect for the genitive-dative case. English determiners are mostly frozen (this, that, my, much — only this/these even bends for number); Romanian determiners are a flexing system. And the good news is that the same endings recur across the whole system — once you internalize the -ă / -i / -e feminine-and-plural pattern, you can predict the form of a determiner you have never drilled.

💡

Read this page as a map, not a memory test. The point is not to memorize every cell but to see the pattern: the feminine singular tends to end in -ă (această, mea, multă), the masculine plural in -i (acești, mei, mulți), the feminine/neuter plural in -e (aceste, mele, multe). When you spot those three endings echoing across demonstratives, possessives, and quantifiers alike, the system stops being five separate paradigms and becomes one.

How to use this grid

Pick the determiner family, find the row for your noun's gender and number, and — if the noun is in the genitive or dative — switch to the gen-dat form. Then place the determiner correctly: articles and most quantifiers and demonstratives can precede the noun (bare noun) or, for demonstratives, follow it (articled noun); possessives normally follow the articled noun. The placement rules live on the family pages; this grid is purely about which form agrees.

The master agreement grid

Family	Masc. sg.	Fem. sg.	Masc. pl.	Fem./Neut. pl.	Gen-Dat sg. (m / f)	Gen-Dat pl.
Definite article (suffix)	-ul / -le	-a	-i / -ii	-le	-lui / -ei	-lor
Indefinite article	un	o	niște	niște	unui / unei	unor
Demonstrative "this"	acest	această	acești	aceste	acestui / acestei	acestor
Demonstrative "that"	acel	acea	acei	acele	acelui / acelei	acelor
Possessive "my"	meu	mea	mei	mele	(invariable for case)
Possessive "your" (sg.)	tău	ta	tăi	tale	(invariable for case)
Quantifier "much/many"	mult	multă	mulți	multe	(invariable for case)
Quantifier "all/whole"	tot	toată	toți	toate	(via following article)
cel buffer article	cel	cea	cei	cele	celui / celei	celor

Look down the Fem. sg. column: -a (article), o, această, acea, mea, ta, multă, toată, cea — the feminine singular is overwhelmingly an -ă/-a shape. Down the Masc. pl. column: acești, acei, mei, tăi, mulți, toți — almost all in -i. Down the Fem./Neut. pl. column: aceste, acele, mele, tale, multe, toate, cele — the -e plural. That visual rhyme is the whole point of looking at the families side by side.

Articles — gender, number, case via the noun ending

The definite article is a suffix on the noun, so its "agreement" shows up as the ending the noun wears: omul (m. sg.), femeia (f. sg.), oamenii (m. pl.), femeile (f. pl.), with gen-dat omului, femeii, oamenilor. The indefinite article un / o precedes the noun and has its own gen-dat forms unui / unei / unor.

Un coleg mi-a recomandat o carte și niște articole.

A colleague recommended a book and some articles to me.

I-am dat unui coleg cheia și unei colege dosarul.

I gave the key to one (male) colleague and the file to one (female) colleague. (gen-dat — unui / unei)

Demonstratives — full case paradigm

The demonstratives are the determiners that bend the most: gender, number, and a full genitive-dative. Acest / această / acești / aceste in the nominative-accusative; acestui / acestei / acestor in the genitive-dative. The "that" series acel / acea / acei / acele → acelui / acelei / acelor mirrors it exactly. (The post-noun forms acesta / aceasta / aceștia / acestea are covered on demonstratives acest/acel.)

Aceste fotografii sunt mai vechi decât acelea.

These photos are older than those.

Răspunsul acestei studente a fost cel mai bun.

This student's answer was the best. (genitive — acestei)

Possessives — agree with the thing possessed

The possessives agree with what is owned, not the owner, and they do not inflect for case themselves (the noun's article and any preceding genitival article handle case). Meu / mea / mei / mele tracks the gender and number of the possessed noun: câinele meu (m.), pisica mea (f.), câinii mei (m. pl.), pisicile mele (f. pl.).

Frații mei și surorile mele vin la cină.

My brothers and my sisters are coming to dinner.

Părerea profesorului meu contează mult pentru mine.

My professor's opinion matters a lot to me. (case is on profesorului; meu stays put)

💡

A reliable shortcut for possessives: ignore the owner entirely and ask only "what gender and number is the thing owned?" Câinele meu / pisica mea / câinii mei / pisicile mele all mean "my…" — the meu/mea/mei/mele shift tracks câine/pisică, never the speaker. English glues "my" to the owner; Romanian glues the possessive to the possessed.

Quantifiers — gender and number

Mult / multă / mulți / multe ("much, many") and puțin / puțină / puțini / puține ("little, few") agree in gender and number. Tot / toată / toți / toate ("all, whole") also agrees, with the quirk that it sits before the definite article: tot orașul ("the whole city"), toate orașele ("all the cities"). These quantifiers are detailed on the quantifiers page.

Am puțin timp, dar multă energie azi.

I have little time but a lot of energy today. (puțin masc. for timp, multă fem. for energie)

Toți copiii și toate fetele au plecat în excursie.

All the boys and all the girls went on the trip.

The cel buffer article

Finally, the buffer article cel / cea / cei / cele (gen-dat celui / celei / celor) re-marks definiteness on detached modifiers, ordinals, and numerals. It is fully inside the same agreement system — its forms are identical in shape to the demonstrative plurals and the cele/cei endings you already know. See the cel buffer article for its uses.

Cei doi frați și cele trei surori au moștenit casa.

The two brothers and the three sisters inherited the house.

Common Mistakes

The dominant error category for English speakers is leaving a determiner uninflected — treating it like the frozen English this/my/much — either failing to agree in gender/number or failing to mark the gen-dat case.

❌ mult energie

Gender mismatch — energie is feminine, so the quantifier is multă: multă energie.

✅ multă energie

a lot of energy

❌ frații meu

Number mismatch — a plural possessed noun takes mei: frații mei.

✅ frații mei

my brothers

❌ părerea această studentă

No gen-dat marking — the genitive needs acestei and the inflected noun: părerea acestei studente.

✅ părerea acestei studente

this student's opinion

❌ tot orașe

Number mismatch — plural 'all the cities' is toate orașele; tot is the singular.

✅ toate orașele

all the cities

❌ I-am dat cheia un coleg.

No gen-dat on the indefinite article — the dative needs unui: I-am dat cheia unui coleg.

✅ I-am dat cheia unui coleg.

I gave the key to a colleague.

Key Takeaways

Every Romanian determiner inflects for gender and number; the prenominal ones (articles, demonstratives, cel) also inflect for the genitive-dative.
The forms rhyme across families: feminine singular tends to -ă/-a, masculine plural to -i, feminine/neuter plural to -e — and the gen-dat to -ui / -ei / -or.
Possessives agree with the thing possessed (not the owner) and do not carry case themselves; the noun's article does.
The single biggest learner error is leaving a determiner uninflected — agree it in gender, number, and (where it applies) case, every time.
