Ask too many questions (3)
I believe the answer is:
pry
'ask too many questions' 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 "Interfere" , "Intrude" , "Be inquisitive" , "Intrusively enquire" , "Look inquisitively into private matters" .)
