Snoop around (3)
I believe the answer is:
pry
'snoop around' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for pry that I've seen before include "Intrusively enquire" , "Be nosy" , "Interfere" , "Poke into matters not your concern" , "Look intrusively" .)
