Can't it be "thank you for your help"? In some other examples the "the" form could be changed for persone i.e. "the leg" -> "his leg" or something like that
It could be "thanks for the help". The sentiment is the same as "thanks for your help" but you would need a possessive pronoun. The thing you're talking about is mostly only with body parts.
Kan man simpelt sige "Tak for hjælp"?
Where is "you" in this sentence. It should be "thanks for helping", no?
I wrote "Thanks for the help" and it is marked as incorrect. I object, my answer was perfectly correct.
