Active and Passive Voice


In English grammar, voice refers to the form of a verb that shows whether the subject performs or receives the action. There are two types of voice: active voice and passive voice.

Active Voice

A sentence is in active voice when the subject performs the action. This structure makes sentences clear and direct. The pattern is:

Subject + Verb + Object

Examples:

  • She writes a letter.
  • They cleaned the room.
  • The teacher explained the lesson.

Passive Voice

A sentence is in passive voice when the focus is on the action rather than the doer. The object of the active sentence becomes the subject in the passive sentence. The pattern is:

Object + be (is, am, are, was, were, been) + past participle + (by + subject, if needed)

Examples:

  • A letter is written by her.
  • The room was cleaned by them.
  • The lesson was explained by the teacher.
