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.

Examples:

• 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).

Examples:

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