An adverb is a word that modifies (describes) a verb (“he sings loudly”), an adjective (“very tall”), another adverb (“ended too quickly”), or even a whole sentence (“Fortunately, I had brought an umbrella.”). Adverbs often end in -ly, but some (such as fast) look exactly the same as their adjective counterparts.

Tom Longboat did not run badly.

Tom is very tall.

The race finished too quickly.

Fortunately, Lucy recorded Tom’s win.

It’s easy to identify the adverbs in these sentences.

Adverbs and verbs

Adverbs often modify verbs. This means that they describe the way an action is happening.

Huan sings loudly in the shower.

My cat waits impatiently for his food.

I will seriously consider your suggestion.
