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
