Adverb

 An adverb is a word or phrase that modifies a verb, adjective, or other adverbs, typically by adding more information about manner, time, place, or degree. Adverbs often end in "-ly," such as "quickly," "quietly," or "brilliantly," although not all do. Here are some examples of adverbs in sentences:

1. He runs quickly.
2. She plays the piano beautifully.
3. They work quietly in the library.
4. The cat naps loudly in the corner.
5. We study diligently for exams.
