Questions & Answers about Det kan gjøres i morgen.
Here det is the subject, like English it in It can be done tomorrow.
It can do two jobs here:
- It can refer to something already understood from context: a task, a plan, a repair, etc.
- It can also function as a more general dummy subject, because Norwegian usually wants an explicit subject in a full clause.
So even if the real thing being talked about is not named in the sentence, det is still natural and often necessary.
Because the sentence is passive.
- gjøre = do
- gjøres = be done / get done in an -s passive form
Compare:
- Vi kan gjøre det i morgen. = We can do it tomorrow.
This is active. - Det kan gjøres i morgen. = It can be done tomorrow.
This is passive.
So gjøres is used because the focus is on the action being done, not on who does it.
