What is a verb?

Response:
A verb is an action word that describes an activity.  Examples of verbs are the following: swimming, hiking, biking, roller skating, or skydiving.  All of these single and combination word examples are tied to an activity that any living thing can do.  For example, a dog can bike ride with a human when the human is pedaling the bike.  Verb use is not limited to humans or people only but applies to all living things.
