Point to it and select a carp (7)
I believe the answer is:
nitpick
'a carp' is the definition.
(both can mean to find fault with something)
'point to it and select' is the wordplay.
'point' becomes 'n' (North).
'to' is a charade indicator (letters next to each other).
'and' says to put letters next to each other.
'select' becomes 'pick' (picking is a kind of selecting).
'n'+'it'+'pick'='NITPICK'
(Other definitions for nitpick that I've seen before include "Be fussy and pedantic" , "Pedantically find fault" , "Find fault fussily" , "Raise petty objections" , "Make petty criticisms" .)
