Final answer:
Synonyms are words with similar meanings, while homophones sound the same but are spelled differently. Antonyms have opposite meanings.
Explanation:
Synonyms are words that have the same or similar meaning to another word, like 'fast' and 'rapid' which are synonyms because they both describe quick speed.
Homophones, on the other hand, are words that sound the same but have different spellings and meanings, such as 'there,' 'their,' and 'they're.'
Antonyms are words that have opposite meanings, like 'hot' and 'cold' or 'happy' and 'sad'.
