Questions & Answers about Dragkedjan på väskan är helt trasig, så jag måste reparera den.
Why do we use på to express 'of the' in dragkedjan på väskan?
This sentence demonstrates the Swedish preference for spatial prepositions over the s-genitive when talking about inanimate part-whole relationships. Because the zipper is physically attached to the outside of the bag, we use på (on). Translating 'of' directly to av would sound very unnatural here.
Would it be grammatically wrong to use the s-genitive and say väskans dragkedja instead?
It is not strictly wrong and would be perfectly understood, but dragkedjan på väskan sounds much more idiomatic. Swedish speakers generally avoid the s-genitive for everyday physical objects belonging to other objects, preferring prepositional phrases.
What is the difference between saying the zipper is trasig versus saying it is sönder?
In this specific sentence, you could actually use either: är helt trasig or är helt sönder. The difference is that trasig is a standard adjective that changes form to match its noun, while sönder is an unchangeable particle mostly used with verbs (like gå sönder meaning 'to break').
Dragkedjan looks like a long word. How is it constructed?
It is a literal compound combining drag (a pull, related to the verb dra) and kedja (chain). So a zipper in Swedish is a 'pull-chain'. Recognizing how these compounds are built makes it much easier to memorize new vocabulary!
