Reflexive possessives (sin, sitt, sina)

In English, "He washes his car" is ambiguous: is it his own car, or another man's? Swedish eliminates this by using reflexive possessives when a third-person subject (he, she, it, they) owns the object.

  • Use sin, sitt, or sina if the object belongs to the subject ("their own").
  • Use hans, hennes, dess, or deras if it belongs to someone else.

The form matches the gender and number of the noun being owned, not the owner.

Sin (En-words)

Compare these sentences. Notice how sin means "his own," while hans means the car belongs to another man:

The man washes his (own) car.
Mannen tvättar sin bil.
The woman washes his car.
Kvinnan tvättar hans bil.
The father reads his (own) book in the house.
Pappan läser sin bok i huset.
He drops his (own) key.
Han tappar sin nyckel.

Sitt (Ett-words)

Use sitt for singular ett-words:

The boy forgets his (own) umbrella.
Pojken glömmer sitt paraply.
The child holds its (own) apple.
Barnet håller sitt äpple.

Sina (Plural)

Use sina for plural nouns. This applies even with multiple owners ("they"), as long as the subjects act on their own things:

They sell their (own) cars.
De säljer sina bilar.
He sells their cars.
Han säljer deras bilar.
The mother hugs her (own) children.
Mamman kramar sina barn.
She hugs his dogs.
Hon kramar hans hundar.

In Questions

The rule applies exactly the same way in questions:

Does the girl fetch her (own) umbrella?
Hämtar flickan sitt paraply?
Is the man looking for his (own) jacket?
Söker mannen sin jacka?

(Note: Because *sin, sitt, and sina refer back to the subject of the clause, they can never be the subject themselves!)*
