Passive Voice

In English, sentences can be in active voice or passive voice. In active voice, the subject performs the action. In passive voice, the subject receives the action.

  • Active: She writes a letter. (Subject does the action)
  • Passive: A letter is written by her. (Subject receives the action)

Passive Voice Structure

Formula: Object + be (conjugated) + past participle + (by + subject)

The "by + subject" part is optional and often omitted.
