An antonym is a word that has the _____ meaning of another word.

An antonym is defined as a word that has the opposite meaning of another word. For example, "hot" is an antonym of "cold," as the two words convey opposing concepts. The concept of antonyms is fundamental in understanding language and vocabulary because it helps clarify meanings and creates contrast in expression. Recognizing antonyms enriches linguistic skills, aiding in both comprehension and communication by providing nuanced ways to convey differences in meaning. In contrast, the other options refer to relationships that do not align with the definition of an antonym: "same" implies similarity rather than opposition, "similar" suggests that the meanings are alike, and "related" indicates a connection without specifying the nature of the differences in meaning. Thus, understanding that antonyms represent opposite meanings is key to grasping their role in language.
