What is Vocabulary?
The term vocabulary refers to the words and phrases that a person or group of people knows. When you start off learning a language you won't know many words and you will therefore have a small vocabulary. As your knowledge of a language grows, your vocabulary will grow too. Someone who is fluent in a language will have a large vocabulary. You can read a longer definition in our Vocabulary Definition.
