What are Agent Prepositions? | Examples, Tip & Trick & PDF

Definition of Agent Preposition

An agent preposition is a type of preposition that shows the person or thing that performs the action of the verb in a sentence. The agent preposition is used in sentences with the active voice. It’s important to note that not all prepositions that introduce an agent are agent prepositions. For example, prepositions like “with” and “by” can also introduce an agent in a sentence, but they are not considered agent prepositions.

Usage of Agent Prepositions

Agent Preposition in Active Voice

Agent prepositions are used in sentences with an active voice. In an active voice sentence, the subject of the sentence performs the action of the verb. For example, in the sentence “The cat chased the mouse,” the cat is the subject and is performing the action of chasing.

Agent Preposition in Passive Voice

Agent prepositions are also used in passive voice sentences, where the subject of the sentence receives the action of the verb. In a passive voice sentence, the agent preposition is often introduced by the preposition “by.” For example, in the sentence “The mouse was chased by the cat,” the mouse is the subject and is receiving the action of being chased by the cat.
