* Example: She quickly ran to the store.
* Adjectives: Adverbs can modify adjectives, providing further description.
* Example: The extremely tall building reached for the sky.
* Other adverbs: Adverbs can modify other adverbs, creating a more complex description.
* Example: The car drove incredibly slowly down the street.
