A polyglot is a person who can speak, read, or write in multiple languages. While there is no strict definition of how many languages one must know to be considered a polyglot, it typically refers to someone who is fluent in at least five languages. Polyglots often have a passion for languages and enjoy learning about different cultures. Many polyglots use various methods to acquire new languages, such as language courses, immersion experiences, or language exchange with native speakers. Some well-known polyglots, like Benny Lewis and Luca Lampariello, share their techniques and tips online, inspiring others to learn new languages.
