Questions & Answers about Det gjør så vondt i ankelen at jeg ikke kan gå.
In Norwegian, det is often used as a kind of dummy subject in sentences about weather, general situations, or bodily sensations.
Here, Det gjør så vondt ... literally looks like It does so painful ..., but the natural meaning is simply It hurts so much ...
So det does not refer to a specific thing. It is just there because Norwegian usually wants a subject in the sentence.
Gjøre vondt is a fixed expression meaning to hurt or to be painful.
- Det gjør vondt = It hurts
- Det gjør veldig vondt = It hurts a lot
A learner might expect something like er vondt because vondt looks like an adjective, but with physical pain Norwegian commonly uses gjøre vondt, not just være vondt.
So:
- Det gjør vondt i ryggen = My back hurts / It hurts in my back
- Det gjør vondt i ankelen = My ankle hurts
