What are Synonyms and Antonyms? How Can They be Used in Sentences?

Synonyms are words that have similar meanings, while antonyms are words with opposite meanings. For example, "happy" and "joyful" are synonyms, while "happy" and "sad" are antonyms. In sentences, synonyms can be used to avoid repetition and add variety, like "The dog is big" becomes "The dog is large." On the other hand, antonyms can be used for contrast or to emphasize differences, such as "The water is hot" and "The ice is cold." Understanding synonyms and antonyms helps to enrich vocabulary and improve language expression.
