Use a crowbar (3)
I believe the answer is:
pry
'use a crowbar' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for pry that I've seen before include "Inquire intrusively" , "Look intrusively" , "Enquire too inquisitively" , "Stick nose into other's business" , "Intrusively enquire" .)
