Danish grammar
Reflexive possessive pronouns (sin, sit, sine)
Reflexive possessive pronouns are used when the possessor is the same as the subject of the sentence. In Danish, these are sin (common singular), sit (neuter singular), and sine (plural).
They are only used for the 3rd person (he, she, it, they) and refer back to the subject. For other persons, the normal possessive pronouns are used (min, din, vores, etc.).
This is a new concept for most learners because it does not exist in English. English uses the same possessive pronouns (his, her, its, their) whether the object belongs to the subject or to someone else, which can cause ambiguity. Danish avoids this ambiguity by having special reflexive forms to show clearly when the object belongs to the subject.
