Seduction ruined eminent 'tec (10)
I believe the answer is:
enticement
'seduction' is the definition.
(thesaurus)
'ruined eminent 'tec' is the wordplay.
'ruined' indicates anagramming the letters.
'eminent'+'tec'='eminenttec'
'eminenttec' anagrammed gives 'ENTICEMENT'.
(Other definitions for enticement that I've seen before include "Something which tempts" , "Carrot" , "Something alluring" , "Attraction" , "A lure" .)
