What is the term for words that have similar meanings?

The term for words that have similar meanings is synonyms. Synonyms are words that can be used interchangeably in certain contexts because they convey the same or similar meanings. For example, the words "happy" and "joyful" can be considered synonyms as they both express a positive emotional state.

Understanding synonyms is important for enhancing vocabulary and improving writing skills, as they allow for greater expression and variety in language use. This can help avoid repetition and can make communication more engaging and precise.

The other terms, while related to language, refer to different concepts: antonyms are words that have opposite meanings, homonyms are words that sound alike but have different meanings, and metonyms are words that substitute one term for another closely related term. Each of these serves a distinct purpose in language and vocabulary, differentiating them from the concept of synonyms.
