Genitive -s: flickans, Sveriges

To show who something belongs to, Swedish adds -s to the owner, with no apostrophe: Anna → Annas cykel (Anna's bike).

• names, places and countries: Eriks fru, Sveriges huvudstad
• definite nouns: flickan → flickans väska, huset → husets tak, barnen → barnens rum
• indefinite nouns: en kvinnas röst, barns rättigheter
• with min, din and so on, the -s goes on the noun: min brors bil

The thing that is owned stays in the indefinite form, without -en or -et: pappas bil, never pappas bilen. A name that already ends in -s gets no extra -s (Lars bil).
