Learn Croatian: Sela i jezera su lijepa. - Villages and lakes are beautiful.

Regular neuter nouns in Croatian, which usually end in -o or -e in the singular (like selo and jezero), form their plural by changing that final letter to an -a. So sela means "villages" and jezera means "lakes".

Wait, since sela, jezera, and lijepa all end in "-a", don't they look exactly like feminine singular words?

They do! It is very common for beginners to mix them up. While most feminine singular words end in -a, neuter plural nouns and adjectives also end in -a. You can easily tell this sentence is plural because it uses the plural verb su (are) instead of the singular je (is).

Why is the adjective lijepa instead of lijepi or lijepe?

Adjectives always change their endings to match the noun they are describing. Because both sela and jezera are neuter plural nouns, the adjective must take the neuter plural ending, which happens to be -a.

Could I put the verb su at the very beginning of the sentence?
