Plural possessives

To show possession with regular plural nouns add an apostrophe (‘) at the end.

  • Airplane’s wings
    (one airplane)
    Airplanes’ wings
    (many airplanes)
  • The cats’ beds
  • Two-year olds’ activities

To show possession with irregular plural nouns add an apostrophe and -s at the end.

  • Your child’s toys
    (one child)
    Your children’s toys
    (many children)
  • The sheep’s wool
    (one sheep)
    The sheep’s wool
    (many sheep)
  • Father-in-law’s duties
    (one father-in-law)
    Fathers-in-law’s duties
    (many fathers-in-law)

If many nouns possess another noun then only the last noun is in the possessive form.

  • Juliet, Romeo and William’s holiday is next week.
    (They will all go on holiday together next week.)
  • William and Mary’s house is at the end of the street.

If many nouns possess their own noun then all of the nouns will be in the possessive form.

  • Juliet’s, Romeo’s and William’s holidays are next week.
    (They will all go on different holidays next week.)
  • William’s and Mary’s houses are next to each other.
