Subject, object, passive, active

  • Subject & object nouns and passive & active voice are key terms in grammar
  • A subject noun is the noun that performs the action of the sentence – The cat chased the mouse
  • An object noun is the noun that receives the action of the sentence (mouse)
  • In the active voice the subject of a sentence performs the action
  • In the passive voice the object becomes the subject even though it does not perform the action - The mouse was chased by the cat
