Pig was taken by husband? Nonsense! (7)
I believe the answer is:
hogwash
'nonsense' is the definition.
(I've seen this before)
'pig was taken by husband?' is the wordplay.
'pig' becomes 'hog' (synonyms).
'taken by' means one lot of letters go next to another.
'husband?' becomes 'h'.
'hog'+'was'+'h'='HOGWASH'
(Other definitions for hogwash that I've seen before include "bull" , "Bunk" , "Colloquial nonsense to pig cleanser" , "Utter rubbish" , "Bunkum" .)
