Does this mean a case, as in a court case, or like a briefcase?
It could be a court case, a matter, a situation, an abstract thing to be taken into consideration.
Is "ser" "see" and "ser på" " look"?
Ser = is/am/are seeing/looking. Ser på = is/am/are seeing/looking at.
Think of ser på being a phrase in itself, meaning 'looking at' if you're struggling :)
We see the case. We view the case. No difference.both should be OK
Thought "ser på" meant watching... guess not? any tips to differentiate between watch, see, and look?
I think "ser på" can mean watch and look at.
As ever, context is everything.
