Where Epicurus came from when rejecting spicy snacks? (5)
I believe the answer is:
samos
'where epicurus came from' is the definition.
(the philosopher Epicurus came from Samos)
'when rejecting spicy snacks?' is the wordplay.
'when' becomes 'as' (eg 'when I walked' means 'as I walked').
'rejecting' is a deletion indicator.
'spicy snacks?' becomes 'samosas' (samosas are spicy pastries).
'samosas' with 'as' taken away is 'SAMOS'.
(Other definitions for samos that I've seen before include "somewhere in the Aegean" , "birthplace of Pythagoras" , "Aegean Sea island" , "Greek island?" .)
