Questions & Answers about Han värmer halsen med halsduken.
Why does the sentence use halsen (the neck) and halsduken (the scarf) instead of translating the word 'his'?
This is a classic example of inalienable possession. In Swedish, when it is completely obvious from the context that a body part or an item of clothing belongs to the subject, you just use the definite form (the) instead of a possessive pronoun like hans or sin.
Is it ever correct to use sin hals or sin halsduk in a sentence like this?
Yes, it is grammatically correct, but it sounds clunky and overly specific to a native ear. You would typically only use sin here if you really needed to emphasize that it was his very own neck or scarf, perhaps to contrast it with someone else's.
How do the words halsen and halsduken relate to each other?
Hals means neck or throat, and duk means cloth or fabric. Put them together, and a halsduk is literally a neck-cloth, which is the Swedish word for a scarf.
If he were warming someone else's neck with his scarf, could we still just say halsen?
No. The definite form only replaces a possessive pronoun if the item belongs to the subject of the sentence (in this case, han). If he were warming his daughter's neck, you would have to specify ownership by saying hennes hals.
