Last letter from Greece (5)
I believe the answer is:
omega
I believe this is a double definition.
'last' is the first definition.
(I've seen this in another clue)
'letter from greece' is the second definition.
(letter from the Greek alphabet)
(Other definitions for omega that I've seen before include "character in Greek literature?" , "Art of story-telling by body movement" , "symbol of resistance?" , "Foreign character" , ""The Alpha and the ___"" .)
