Woman's relaxation generates complaint (7)
I believe the answer is:
disease
'complaint' is the definition.
(I've seen this before)
'woman's relaxation' is the wordplay.
'woman's' becomes 'di's' (Di is short for Diana).
'relaxation' becomes 'ease' (synonyms).
'dis'+'ease'='DISEASE'
'generates' is the link.
(Other definitions for disease that I've seen before include "Ailment, malady" , "Contagion" , "22 [MALADY]" , "scurvy?" , "Sickness" .)
