Which definition best describes antonyms?

Antonyms are best defined as words that are opposite in meaning. This distinction is crucial in understanding the relationship between words within a language. For example, "hot" and "cold" or "happy" and "sad" are pairs of antonyms that illustrate contrasting concepts.

This definition emphasizes the importance of recognizing how antonyms can enhance vocabulary and improve communication by providing clarity and depth in expressing different ideas or qualities. When students learn about antonyms, they develop a more nuanced understanding of language, which is an essential skill in both spoken and written communication. Knowing antonyms can also aid in various learning activities, such as creative writing or discussions, as they allow children to express a broader range of emotions and descriptions.
