"Word meaning" refers to the significance or definition of a word within a language. It encompasses various aspects, including its literal definition, connotations, and the context in which it is used. Understanding word meaning is essential for effective communication, as it helps individuals convey their thoughts accurately and interpret others' messages. Words can have multiple meanings, known as polysemy, where a single word may represent different ideas depending on the context. Additionally, synonyms and antonyms play a role in word meaning, as they provide alternatives and opposites that enrich language. Overall, grasping word meaning enhances comprehension and expression in communication.
