Begs son to pursue job after wasting time (4)
I believe the answer is:
asks
'begs' is the definition.
(I've seen this before)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for asks that I've seen before include "Poses a question" , "Inquires (4)" , "Makes an inquiry" , "Enquires; requests" , "Inquiries" .)
