A female fragrance (5)
I believe the answer is:
aroma
'fragrance' is the definition.
(synonyms)
'a female' is the wordplay.
'female' becomes 'roma' (I can't explain this - if you can you should give a lot more credence to this answer).
'a'+'roma'='AROMA'
Can you help me to learn more?
(Other definitions for aroma that I've seen before include "A pleasant smell as of food" , "Perfume" , "Redolence" , "Stink" , "Distinctive odour" .)
