Share wife with journalist? (5)
I believe the answer is:
whack
'share' is the definition.
(whack can mean a share or contribution)
'wife with journalist?' is the wordplay.
'wife' becomes 'w' (abbreviation).
'with' says to put letters next to each other.
'journalist?' becomes 'hack' (hack can informally mean a journalist).
'w'+'hack'='WHACK'
(Other definitions for whack that I've seen before include "Strike sharply" , "Punch" , "Onomatopoeic blow" , "Hit loudly" , "Strike hard" .)
