Eternal fool to accept point by setter? (7)
I believe the answer is:
ageless
'eternal' is the definition.
(I know that eternal can be written as ageless)
'fool to accept point by setter?' is the wordplay.
'fool' becomes 'ass' (both can mean a stupid person).
'to accept' is an insertion indicator.
'point' becomes 'e' (compass point).
'by' is a charade indicator (letters next to each other).
'setter?' becomes 'gel' (something which sets).
'e' put after 'gel' is 'gele'.
'ass' enclosing 'gele' is 'AGELESS'.
(Other definitions for ageless that I've seen before include "Lasting forever" , "Enduring" , "Classic" , "Small amphibian" , "Lasting a long time" .)
