"Swan Lake” princess (6)
I believe the answer is:
odette
'swan lake princess' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for odette that I've seen before include "1950 film about first female to receive George Cross" , "------ Churchill, French war heroine" , "Part of Swan Lake" , "Lover of Swann" , "Swan Lake role" .)
