She turned to stone (6)
I believe the answer is:
gorgon
'she' is the definition.
Both the definition and answer are singular nouns.
Perhaps there's a link between them I don't understand?
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for gorgon that I've seen before include "Snake-haired monster" , "Unpleasant woman" , "Either Stheno, Euryale or Medusa" , "Mythical sister with snakes for hair" , "In Greek myth, her glance turned people to stone" .)
