Forbidding nurse to bind hip (8)
I believe the answer is:
sinister
'forbidding' is the definition.
(I know that forbidding can be written as sinister)
'nurse to bind hip' is the wordplay.
'nurse' becomes 'sister' (a female nurse might be called sister).
'to bind' means one lot of letters goes inside another.
'hip' becomes 'in' (both can mean fashionable).
'sister' placed around 'in' is 'SINISTER'.
(Other definitions for sinister that I've seen before include "Forbidding" , "can be injurious" , "Suggestive of evil, threatening harm" , "Eerie, alarming" , "Suggesting or threatening evil or danger" .)
