Here's why:
* Homonyms: Words that sound alike and are spelled the same way, but have different meanings (e.g., "bear" the animal and "bear" to carry).
* Synonyms: Words that have the same or similar meaning (e.g., "happy" and "joyful").
While homonyms have the same sound and spelling but different meanings, synonyms have the same meaning but different sounds and spellings.
