Go away and ask somebody (6)
I believe the answer is:
begone
'go away' is the definition.
(I've seen this before)
'ask somebody' is the wordplay.
'ask' becomes 'beg' (begging is a kind of asking).
'somebody' becomes 'one' (I've seen this in other clues).
'beg'+'one'='BEGONE'
'and' is the link.
(Other definitions for begone that I've seen before include "shove off" , "Archaic command to go away, banish" , "get lost" , "Take a hike" , "make himself scarce" .)
