Fragments are incomplete sentences used as complete sentences. Fragments are common in normal speech but shouldn’t be used in formal writing.


  • ‘When’s his birthday?’
  • ‘What did he do?’
    ‘Shut the door and left.’
    (no subject but in a conversation it is OK)


  • Looking forward to seeing you.
    (no subject)
    I’m looking forward to seeing you.
    (in writing you need to add a subject/I’m)
