Synonyms and Antonyms — Answer Key
Part A: Fix the Sentence
Each sentence has an error. Rewrite it correctly on the line.
1. Fix the sentence:

Corrected: Hot and cold are antonyms.
Antonyms are opposites; warm is close to hot, but cold is the true opposite.

Corrected: Up and down are antonyms.
Up and down point in opposite directions, which makes them antonyms, not synonyms.

Corrected: The antonym of happy is sad.
Cheerful means happy; sad is the opposite feeling, so sad is the correct antonym.
