I will be embraced by not entirely virtuous woman (5)
I believe the answer is:
moira
'woman' is the definition.
'i will be embraced by not entirely virtuous' is the wordplay.
'will be embraced by' means one lot of letters goes inside another.
'not entirely' means to remove the last letter.
'virtuous' becomes 'moral' (similar in meaning).
'moral' with its last letter taken off is 'mora'.
'i' going inside 'mora' is 'MOIRA'.
(Other definitions for moira that I've seen before include "Any of the three Greek Fates" , "Shearer perhaps" , "- - Shearer, actress-ballerina" , "Girl" , "-- Shearer, ballet dancer" .)
