The past participles are formed by adding –ed to the base form of regular verbs (fire – fired, jump – jumped, move – moved) or by adding other endings to the base form of irregular verbs (be – been; feel – felt, hide – hidden) as they do not end in –ed or by changing their spellings (fight – fought, see – saw, teach – taught).  The past participle expresses a completed action in the past. It must come after the helping verbs or auxiliary verbs have (havehashad) to form the perfect tenses in the active voice or be (isarewaswere) in the passive voice. The past participle may also be used as adjectives to modify nouns or pronouns. When it modifies a noun, it functions as an adjective and is known as a participial adjective.



Past participle used in the perfect tenses in the active voice. 
Perfect tenses must use the past participle to follow the auxiliary verbs hashave and had.



  • She has broken another of my glasses. (Present perfect)
  • Many passersby have accepted the leaflets that we are handing out. (Present perfect)
  • The hospital had already discharged her when we arrived to visit her. (Past perfect)
  • By the end of this month, her sister will have given birth to her seventh child. (Future perfect)  




Past participle used in the passive voice.
Only the past participle form of the verb can be used in the passive voice. The past participle must immediately follow an auxiliary verb. Both the auxiliary verbs and past participles are shown in bold.



  • She is given the nickname 'Chatterbox' because she talks much more than others. (Present tense)
  • The children are paid to carry banners reading ‘The world will end soon!’ (Present tense)

  • Painting of the doghouse will have been completed by the time the dog arrived. (Future perfect tense)  




Past participle used as adjective.
A past participle functions as an adjective to modify a noun and is known as a participial adjective. It usually comes before the noun that it modifies. The following examples show participial adjectives in bold.



  • More than one newspaper had the same headline saying, ‘It’s a one-sided match.’

    (The past participle one-sided acts an adjective modifying the noun match.)

  • The farmer was found guilty of receiving a stolen cow.

  • The polluted river stinks of rotten eggs.  

  • The wounded victim died in the ambulance.

  • The soldiers were shot for straying into the disputed territory.
