Sorceress made out to entrap the heart of men (5)
I believe the answer is:
medea
'sorceress' is the definition.
(I've seen this before)
'made out to entrap the heart of men' is the wordplay.
'out' indicates anagramming the letters (out can mean wrong or inaccurate).
'to entrap' means one lot of letters goes inside another.
'the heart of' means to look at the middle letters.
The middle letter of 'men' is 'e'.
'made' with letters rearranged gives 'meda'.
'meda' going around 'e' is 'MEDEA'.
(Other definitions for medea that I've seen before include "Greek princess who helped Jason obtain the Golden Fleece" , "Tragic heroine" , "Sorceress who helped Jason get the Golden Fleece" , "In Greek myth, Jason's wife who killed their children in jealous rage" , "Mythological Greek princess" .)
