Letter from egalitarian characters (5)
I believe the answer is:
omega
'letter' is the definition.
(I know that omega is a type of letter)
'from egalitarian characters' is the wordplay.
'characters' indicates the answer is hidden within the clue (some letters or characters from the clue).
'OMEGA' is hidden within 'from egalitarian'.
(Other definitions for omega that I've seen before include "symbol of resistance?" , "end of series" , "letter to Greeks" , "Greek character symbolizing resistance" , "Conclusion" .)
