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:
The words 'tiny' and 'small' are antonyms.
Corrected: The words 'tiny' and 'small' are synonyms.
Synonyms have similar meanings; tiny and small both mean very little in size.
2. Fix the sentence:
The pair 'hot' and 'cold' is a synonym pair.
Corrected: The pair 'hot' and 'cold' is an antonym pair.
Antonyms are word pairs with opposite meanings, like hot and cold temperatures.
