Some other message for Olympian messenger (6)
I believe the answer is:
hermes
'olympian messenger' is the definition.
(I've seen this in another clue)
'some other message for' is the wordplay.
'some' says the answer is hidden in the clue (some parts of the word are used).
'HERMES' is hidden in the letters of 'other message for'.
(Other definitions for hermes that I've seen before include "Messenger and herald of the gods" , "Greek messenger of the gods, like Roman Mercury" , "Greek god of commerce and theft" , "Greek messenger god" , "Winged messenger" .)
