OF

We use the preposition OF to say who or what has a particular feature, aspect, or quality:

  • Rome is the capital of Italy.
  • We were impressed by the size of the building.
  • You don't know the secret of the game.

The genitive case

The genitive case refers to things owned by people, but it can also be used with animals and organizations.

With nouns, we usually add 'S to the word:

  • This is Tom's car.
  • These are my sister's clothes.
  • What are the government's plans?

If the object belongs to more than one person, we add 'S to the last one:

  • This is Claire and Tom's car.

If the object belongs to more than one person and the noun is plural, we add ' to it:

  • Today is the twins' birthday.
