Learn Romanian: Tu ai o haină și ea are niște haine. - You have a coat and she has some coats.

haină is a feminine noun ending in -ă. A very common rule in Romanian is that feminine nouns ending in -ă change this ending to -e in the plural. This is exactly how we get from o haină (a coat) to haine (coats).

Why do we use niște before haine?

niște translates to 'some.' In Romanian, it acts as the plural form of the indefinite articles un (a/an) and o (a/an). We use it here to indicate an unspecified number of coats: niște haine (some coats).

I see both ai and are in this sentence. Are they the same verb?

Yes, they are both forms of the irregular verb a avea (to have). It changes its form depending on the subject: tu ai is 'you have' (singular informal), and ea are is 'she has'.

Can I drop the pronouns tu and ea in this sentence?

Yes, you usually can! Romanian verbs already tell you who is doing the action. You could just say ai o haină și are niște haine. However, including tu (you) and ea (she) emphasizes the contrast between what YOU have and what SHE has.
