Here's why:
* "LY" words are usually adverbs. Adverbs modify verbs, adjectives, or other adverbs. They often end in "-ly" (e.g., quickly, happily, slowly).
* Verbs are action words. They describe what someone or something does (e.g., run, jump, eat, sleep).
Example:
* Verb: The dog ran quickly.
* Adverb (LY word): The dog ran quickly.
In this example, "ran" is the verb, and "quickly" is the adverb modifying the verb.
