Vocabulary refers to the set of words and phrases that a person knows and understands. It includes all the words in a specific language that one can use to communicate and express thoughts, ideas, and feelings. Vocabulary also includes the ability to recognize and comprehend the meaning of words when reading or listening.
For example, if someone knows the words “dog,” “cat,” and “bird,” those words are part of their vocabulary. When they see a picture of a dog and say “dog,” they are using their vocabulary to identify and name the animal.
