"Jeg har sengetøjet under min stol."

Translation: I have the bed sheet under my chair.

what a wild night...

Sengetøjet = one sheet or a set of sheets?

[emilkris33]

One sheet is "et lagen"
"Sengetøjet" is "bedclothes" i.e. the sheet, the blanket and the pillow casing.
So yes I think this sentence is wrong

Is it common in Danmark?

[Rich524475]

American English would only say "I have the sheet" not "the bed sheet". If it needed to be clearer the language would be "I have the sheet for the bed under my chair." Bed sheet would be understood but viewed awkward speach.

[DRm81w]

I disagree. I would definitely say "the bed sheet" before I would say "the sheet for the bed," if I needed to be clear I wasn't talking about a sheet of paper, for example. The second formulation is the awkward one.

If I am to guess the meaning of sengetojet from this sentence it is nearby impossible.

I read it as "seng" (bed) and "tøj" (clothes) and guessed it would be pajamas. I was wrong :(
