Have a look at (3)

I believe the answer is:
see
'have a look at' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for see that I've seen before include "Observe - diocese" , "Glimpse; get" , "ecclesiastical division" , "Observe the bishop's jurisdiction" , "Perceive; meet (someone)" .)
