Genitive s or of-phrase

s-Genitive and/or of?

There is no strict rule when we use 's and when the of-phrase.

1. s-Genitive – mostly for people and animals

  • Ronny's bike
  • the cat's basket

2. of-phrase – mostly for things

  • the name of the school
  • the top floor of the building

If things have a connection to people we also use the s-genitive (possessive).

  • Germany's economy = the ecomony of Germany

In time expressions we also use the s-genitive (possessive).

  • a three weeks' holiday
