Reflexive Possessive 'Sin'
Grammar Rule in 30 Seconds
Use 'sin', 'sitt', or 'sina' when the possessor is the subject of the same clause.
- Use 'sin/sitt/sina' if the owner is the subject: 'Han tvättar sin bil' (He washes his own car).
- Use 'hans/hennes/deras' if the owner is NOT the subject: 'Han tvättar hans bil' (He washes his [someone else's] car).
- Match the gender and number of the object, not the owner: 'sin' (en-word), 'sitt' (ett-word), 'sina' (plural).
Overview
sin, sitt, sina is a vital tool for clarity. When you want to say that someone owns something, and that person is the subject of the sentence, you must use these reflexive forms. If you used hans (his) or hennes (her) instead, it would imply that the object belongs to a third party, not the subject.Han tvättar sin bil means he is washing his own car. If you said Han tvättar hans bil, it would mean he is washing someone else's car. This rule applies exclusively to the third person (he, she, it, they).min or din. Mastering this is the hallmark of moving from a beginner to a confident intermediate speaker.- 1
sin: Use this for singular 'en' words (e.g.,sin bil). - 2
sitt: Use this for singular 'ett' words (e.g.,sitt hus). - 3
sina: Use this for all plural nouns (e.g.,sina barn).
hon), you still use sin if the object is an 'en' word. The gender of the owner does not change the form of the reflexive pronoun.Han glömde sin telefon (He forgot his phone). In professional settings, you might hear Företaget har sålt sin fabrik (The company has sold its factory).Han håller i sin väska is the only correct way to express that. It is rarely used in the first or second person, making it a unique feature of third-person narrative in Swedish.hans or hennes when sin is required. For example, saying Hon tog hennes väska implies she took someone else's bag, whereas Hon tog sin väska means she took her own. Another mistake is trying to use sin for first or second person.Jag tog sin väska; you must say Jag tog min väska. Remember, sin is only for the third person.hans (his) and hennes (her). The difference is purely about the relationship to the subject. If the subject is the owner, use sin/sitt/sina.hans/hennes/deras. Think of sin as a 'subject-pointing' pronoun.Meanings

Kulturelle Hinweise
Swedes value clarity and precision in language. Using 'sin' correctly is seen as a sign of good education.
In some dialects, the use of reflexive pronouns is even more strictly enforced than in mainland Sweden.
Younger speakers might sometimes drop the reflexive in very casual speech, but it is considered non-standard.
The reflexive possessive 'sin' comes from Old Norse 'sinn', which also meant 'one's own'.
