Crude, and eager to put husband down (6)
I believe the answer is:
earthy
'crude' is the definition.
(both can mean vulgar)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for earthy that I've seen before include "Coarse as humour may be" , "Coarse or gross" , "Unrefined - the ray (anag)" , "where we live" , "Hearty and lusty" .)
