Learn Romanian: Doi băieți și două fete studiază engleza.

In Romanian, the number two changes depending on the gender of the noun. We use doi for masculine plural nouns like băieți (boys) and două for feminine plural nouns like fete (girls). You will also use două for neuter nouns. This is a special rule, as most other numbers don't change based on gender!

How does the singular word băiat (boy) become băieți?

When making băiat plural, two spelling changes happen: the vowel a changes to e, and the consonant t changes to ț before the plural ending -i. These sound shifts are very common in Romanian plurals.

Why does the sentence say engleza instead of engleză?

The base word for the English language is engleză. However, in Romanian, when you talk about studying, speaking, or learning a language, you usually attach the definite article (the equivalent of "the") to the end of it. So engleză plus the article -a becomes engleza.

Is studiază the "they" form of the verb?

Yes! The dictionary form is a studia (to study). In Romanian, the "they" form (they study) and the "he/she" form (he/she studies) are often exactly the same for verbs ending in -a. Both are studiază.
