Difference Between Grammar and Vocabulary

Key Difference

Grammar and vocabulary are both fundamental components of language learning and usage, but they serve different roles in communication. Vocabulary refers to the words used in a language, encompassing their meanings, pronunciation, and context of use. It’s the set of words that a person knows or uses.

Grammar, on the other hand, is the set of rules that govern how words are put together in a language to form sentences, phrases, and other speech elements. It includes the structure of sentences, verb tenses, agreement, and syntax.
