Corner fish (5)

I believe the answer is:

angle

I believe this clue is a double definition.

'corner' is the first definition.
(eg a corner of a shape)

'fish' is the second definition.
(angle can mean to fish)

(Other definitions for angle that I've seen before include "Glean (anag.)" , "Early settler" , "Old English settler" , "Point of view; old tribesman" , "Heat (metal) and allow to cool to remove stresses" .)

I've seen this clue in The Guardian, The Times and The Telegraph.
