What are adverbs?

Adverbs are descriptive words which are used to add detail to a sentence. They can give important or necessary information (e.g. Please hand me the scalpel now), or they can just make the sentence more interesting or detailed (e.g. A wind blew violently and unceasingly around the town). Adverbs usually modify verbs, and they frequently end in ‑ly.

Adverbs can be identified by how or where or when:

The dog ran quickly.

How did the dog run? It ran quickly.
