Ni hao! Comment allez-vous? Estoy bien, gracias. Sayōnara! If you understood everything you just read, you’re probably a polyglot — a person who understands multiple languages.
There are thousands of languages spoken in the world, but you don’t need to know them all to be a polyglot. The –glot comes from the Greek word for “tongue,” and the prefix poly- means “more than one,” so if you speak two or more languages, you’re technically a polyglot. Well done! Polyglot can also be used as an adjective, like describing "a polyglot neighborhood" full of people from many different cultures or the "polyglot crowd at the Olympic games."
