1. Active and passive voice

Active and passive voice represent two grammar structures that show whether the subject does the action or receives the action in a sentence.

The table below summarises the difference between these two voices.

Voice Note Example When to use it
Active
  • The subject does the action.
  • The subject receives the action.
 William painted the wall.
  • When you know who does the action.
  • When we want to mention who does the action.
Passive
  • The object becomes the focus of the sentence.
  • The agent performing the action can be omitted.
 The wall was painted by William.
  • When the action is more important than who does it.
  • When you don’t know (or don't want to say) who performs the action in a sentence.

2. Difference

In active voice, the subject comes first, followed by the verb and the object.

  1. I love you.
  2. He needs her.
  3. Donald built this house in 1999.
  4. The police killed the suspect.

A sentence in passive voice uses a conjugated form of to be followed by a past participle.

It follows the structure: object + 'be' verb + past participle + (by + subject).

Study the examples below.

  1. The suspect was killed by the police.
  2. This house was built by Donald in 1999.
  3. This grammar lesson was written by ESL teachers.
