An agent noun is a noun that denotes a person or entity that performs an action or carries out a role related to a specific verb. These nouns are typically formed by adding suffixes such as "-er," "-or," "-ist," or "-ant" to the base form of the verb. For example, in the word "teacher," the agent noun is formed from the verb "teach," indicating someone who teaches. Other examples include "runner" from "run," "actor" from "act," and "artist" from "art." Agent nouns are important for identifying the doers of actions in sentences, helping to clarify who is responsible for a particular activity or role.
