The Definite Article: Feminine (-a, -ua)

You have already met Romanian's signature move with masculine nouns: "the" is not a word in front, it is a suffix glued to the end (băiat → băiatul). Feminine nouns work on exactly the same principle, but with their own set of endings, and they hold a small trap that the masculine forms do not. The feminine definite article is essentially -a, and because so many feminine nouns already end in the vowel -ă, the difference between "a house" and "the house" can come down to a single, easily-missed vowel: casă vs casa. This page lays out the three patterns — -a, -a on -e nouns, and -ua — and the one true irregular.

Pattern 1: nouns ending in -ă → swap to -a

The largest group of feminine nouns ends in unstressed -ă. For these, the definite article replaces the final -ă with -a. Nothing is added; one vowel is exchanged for another.

The exchange of -ă for -a is the most common feminine pattern, and it is also the one that hides the definiteness contrast almost completely — see the section below on the minimal difference.

Pattern 2: nouns ending in -e → add -a

Many feminine nouns end in -e. For these, the article -a is added to the noun. When the -e is preceded by certain vowels, the spelling shows a small adjustment (-ie → -ia), but the principle is simple: keep the noun, append -a.

Note the spelling: carte → cartea, floare → floarea. The final -e and the article -a combine into the written -ea. For nouns ending in -ie, the -e drops and you write -ia: femeie → femeia, familie → familia. This is a spelling convention, not a different rule — you are simply adding the -a article to an -e noun.

Pattern 3: nouns ending in a stressed vowel → add -ua

A smaller group of feminine nouns ends in a stressed vowel, typically -a or -ea carrying the accent. These cannot simply swap or append -a (you would lose the stressed vowel), so Romanian inserts a -u- glide and adds -ua.

The one irregular: zi → ziua

The everyday word zi ("day") is irregular. Its definite form is ziua ("the day"), not zia. You simply have to learn it, because it is extremely high-frequency — it appears in ziua de azi ("today, nowadays"), toată ziua ("all day long"), and the greeting bună ziua ("good day, hello").

The minimal contrast: casă vs casa — "a house" vs "the house"

Here is the trap that the feminine article sets and the masculine does not. With masculine nouns, the definite article -ul adds an obvious syllable: băiat → băiatul. You can hear it. But with the -ă feminine nouns, the only difference between the bare (indefinite/generic) noun and the definite noun is the final vowel: casă (with final -ă, a faint "uh") versus casa (with final -a, a clear "ah").

In English, "a house" and "the house" are unmistakably different — two different little words out front. In Romanian, the whole grammatical contrast between indefinite and definite rides on whether the last vowel is -ă or -a. This is easy to slur in fast speech and easy for a learner's ear to miss, but it is a real, meaning-bearing distinction: Vreau casă ("I want a house / housing in general") is not the same as Vreau casa ("I want the house", a specific one).

Where to go next

You now have both halves of the singular definite article: the masculine/neuter forms (-ul, -le) and the feminine forms (-a, -ua). The next step is the plural definite article (-i, -le), where masculine and feminine diverge again — including the famous triple-i of copiii ("the children"). The articles overview keeps the entire system on one page if you want to see how the pieces fit together.
