Mention something positive about sex-appeal (8)
I believe the answer is:
citation
'mention' is the definition.
(synonyms)
'something positive about sex-appeal' is the wordplay.
'something positive' becomes 'cation' (I am not sure about this - if you are sure you should believe this answer much more).
'about' indicates putting letters inside.
'sex appeal' becomes 'it'.
'cation' going around 'it' is 'CITATION'.
Can you help me to learn more?
(Other definitions for citation that I've seen before include "Quotation from a book" , "Mention in an official report" , "Mention; quoted passage" , "mention in dispatches" , "Commendation for bravery" .)
