Learn Romanian: Blugii sunt ieftini, dar buni. - The jeans are cheap, but good.

The word for jeans is blugi, which is already plural and ends in a single -i. To say the jeans, you add the masculine plural definite article, which is another -i. Together, they form blugii.

Are jeans always a plural noun in Romanian, just like in English?

Yes, blugi acts as a plural noun. That is why the sentence uses the plural verb sunt (are) instead of the singular este (is).

Why do both ieftini and buni end in -i?

Adjectives in Romanian have to match the noun they describe. Because blugii is masculine and plural, the base adjectives ieftin (cheap) and bun (good) both take the masculine plural ending -i.

Do I pronounce the endings of blugii and buni the same way?

No. The single -i at the end of words like ieftini and buni is a very short, whispered sound that just softens the consonant before it. However, the double -ii at the end of blugii is pronounced clearly as a full ee sound.
