Present and Past Participles

The Basics:

  • Participles are based on verbs and express an action or a state of being.
  • The participle, modifier(s), and the (pro)noun that the participle modifies form the participial phrase.
  • Participial phrases are used as adjectives to describe (modify) nouns or pronouns.
  • Present participles end with -ing. (e.g. swimming)
  • Past participles end with -ed, -en, -d, -t, -n, or -ne. (e.g. walked, eaten, craved, dealt, seen, gone)

Examples:

  • Present participle: We are going to the swimming pool. Here, ‘swimming’ modifies the noun ‘pool.’
  • Past participle: After the crime, Mark was a wanted man. Here, ‘wanted’ modifies the noun ‘man.’
  • Participial phrase: Seeing the violence on the basketball court, Jimmy stayed on the swings.

Seeing the violence on the basketball court, Jimmy stayed on the swings.

Punctuation Rules:

  • If your sentence begins with a participial phrase, it should be followed by a comma.
    • Watching a scary movie, Jill felt the need to get up and turn on the lights.
  • If a participial phrase is in the midst of a sentence, it should be surrounded by commas only if it is non-essential information.
  • Essential Information: The boy wearing the red shirt is Jerry.
  • Non-Essential Information: Jerry, seeing the teacher turn her back, threw a spitball.
  • If a participial phrase is at the end of a sentence, it should be preceded by a comma only if it modifies a noun that is not directly before the participial phrase.
    • The teacher often saw Jerry throwing spitballs. (the participial phrase modifies ‘Jerry’)

The cook was seen by the man, making pizza. (the participial phrase modifies ‘the cook’)
