Just look around for prank from pawnbrokers (6)
I believe the answer is:
browse
'just look' is the definition.
The answer and definition can be both acts as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for browse that I've seen before include "Survey" , "Eat by continually nibbling" , "Potter in bookshop" , "Surf (net)" , "Flip through" .)
