Fate, in Greek myth
I believe the answer is:
moira
'fate in greek myth' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for moira that I've seen before include "Shearer perhaps" , "Girl" , "-- Shearer, ballet dancer" , "Any of the three Greek Fates" , "Shearer, possibly" .)
