Learn Polish: Małpy są mądre. - Monkeys are clever.

In Polish, plural nouns are split into two groups: masculine-personal (groups with at least one man) and non-masculine-personal (everything else, including women, animals, and objects). Since monkeys (małpy) are animals, they belong to the non-masculine-personal group. For this group, the plural adjective ending is -e, making it mądre. If you were talking about clever men, you would use mądrzy.

How do we know małpy is the plural form?

The singular word for monkey is małpa, which is a feminine noun because it ends in -a. To make regular feminine nouns plural in the nominative (subject) case, you usually drop the -a and add -y. That gives us małpy.

I have seen mądry translated as wise. Does it also mean clever or smart?

Yes! While mądry is often translated as wise when talking about a person or a deep thought, it is the standard word for smart, clever, or intelligent in everyday Polish. When talking about animals like monkeys, it simply means they are smart.
