Explanation

Synonyms have similar meanings but rarely identical. Consider: happy, joyful, content, pleased – similar but different intensity and context. Choose based on desired nuance.

Antonyms have opposite meanings. Types: graded (hot/cold with degrees between), complementary (alive/dead – no middle), relational (buy/sell – depend on each other).

Context determines synonyms/antonyms. “Light” opposite could be “heavy” (weight) or “dark” (brightness). Always consider the specific meaning in use.
