Learn Croatian: Kina su danas otvorena. - The cinemas are open today.

Kino is a neuter noun, which you can often tell because it ends in -o. To make a regular neuter noun plural in the nominative case, you drop the -o and add -a. So, one cinema is kino, but multiple cinemas are kina.

Why does the adjective otvorena (open) end in -a? Doesn't that usually mean it is feminine?

You are right that -a is the typical ending for feminine singular words. However, it is also the ending for neuter plural words! Adjectives must match the gender and number of the noun they describe. Since kina is neuter plural, the adjective must also take the neuter plural ending, becoming otvorena.

Wait, doesn't the word Kina mean "China" in Croatian? How do we know this sentence is about cinemas?

Great catch! Kina is indeed the Croatian word for China, which is a feminine singular noun. We know this sentence is about cinemas because of the plural verb su (are). If the sentence were about China, it would use the singular verb je (is), making it Kina je danas otvorena (China is open today).

Why is the verb su placed right after Kina instead of next to the adjective?
