There's a lot of this in the Danish lessons.
"was found" ist not correct?
I would also like to know this
The verb at findes (past tense fandtes) means "to exist".
In theory it could also be a passive of at finde (= to find), but I've never heard it used like that. The passive of at finde is always at blive fundet.
Wouldn't you say "kun én nøgle"?
This doesn't seem grammatically correct.
I am wondering along with Pierre Poutine if there should not be a better pronunciation cue for "en" and some kind of accent mark over the e.
'There existed JUST one key for the room' is not accepted yet. Hopefully it will in the future as I consider it equally correct. ( Although a terrible English sentence)
'There was only one key to the room' is now accepted.
