Which term describes words that have opposite meanings?

Antonyms are the correct term for words that have opposite meanings. This concept is essential in understanding the nuances of language, as antonyms provide contrast that can enhance comprehension and expression. For example, the words "hot" and "cold" are antonyms because they represent opposing states of temperature. Recognizing antonyms helps learners grasp the full meaning of vocabulary by understanding the relationships between different words.

The other terms do not fit this definition: synonyms refer to words that have similar meanings, homonyms are words that sound alike but have different meanings (like "bear" the animal and "bare" to uncover), and analogous terms indicate a relationship or similarity between two different things rather than opposites. Understanding antonyms is crucial in developing a robust vocabulary and language skills, making this answer particularly relevant.
