My goal is to become a polyglot. What is a polyglot?
A polyglot is one who speaks multiple languages fluently or at an advanced level. You could also call this person multilingual.
Now technically, according to the dictionary definition, if you speak 2 languages, you can call yourself a polyglot. But in English we generally call someone who speaks 2 languages bilingual, 3 languages trilingual, and only reserve polyglot or multilingual for the person who speaks 4 or more languages.
