Say nothing about wife - is husband inclined to nag? (8)
I believe the answer is:
shrewish
'inclined to nag?' is the definition.
(I've seen this before)
'say nothing about wife is husband' is the wordplay.
'say nothing' becomes 'sh' (I've seen this in other clues).
'about' becomes 're' (regarding**).
'wife' becomes 'w'.
'husband' becomes 'h'.
'sh'+'re'+'w'+'is'+'h'='SHREWISH'
(Other definitions for shrewish that I've seen before include "inclined to nag?" , "Like Kate" , "(Of a woman) nagging" , "Sharp-tongued" .)
