Genitive Case

In order to form a genitive case in English, we add (-'s) at the end of a word. Genitive case usually marks a noun as being the possessor of another noun.


  • Child's toy.
  • Teacher's book.
  • Mike's problem.
  • My brother's car.
  • Somebody else's troubles.

In case a word is plural, we only add (-') at the end of a word.

  • Sisters' secret.
  • Boys' football match.

When both nouns are objects (as opposed to e.g. people), we use (of) insead of (-'s).


  • The end of the story.
  • The victory of justice.
  • The appeal of crime novels.
