Reflexive Possessive Rules
Grammar Rule in 30 Seconds
Use 'sin', 'sitt', or 'sina' when the owner is the subject of the same clause.
- Use 'sin' (en-word), 'sitt' (ett-word), or 'sina' (plural) when referring back to the subject.
- If the owner is NOT the subject, use 'hans' (his), 'hennes' (her), or 'deras' (their).
- The reflexive pronoun must agree with the noun it modifies, not the owner.
