Hogwash from Venus Williams (5)
I believe the answer is:
swill
'hogwash' is the definition.
(I've seen this before)
'from venus williams' is the wordplay.
'from' says the answer is hidden in the clue.
'SWILL' can be found hidden inside 'venus williams'.
(Other definitions for swill that I've seen before include "Hogwash" , "Wet feed for pigs" , "Waste food left in wills" , "Refuse" , "Wet pig feed" .)
