Cronopio
Glorious Imperator
Edit: A better example: The burglar killed the shopkeeper with his gun. Whose gun? The burglar's or the shopkeeper's?
In Swedish, that would be either: Rånaren dödade affärsinnehavaren med sin pistol
or
Rånaren dödade affärsinnehavaren med hans pistol
Both words in bold refer to his gun, but in the first example the gun belongs to the burglar and in the second it belongs to the shopkeeper.
