Winger's cross to bear! (9)
I believe the answer is:
albatross
'winger's' is the definition.
(albatross is a kind of bird)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for albatross that I've seen before include "Long-winged sea-bird, a constant burden" , "Excellent golf score" , "Ancient Mariner bird" , "Large seabird found among lost Arabs" , "Hole played in three strokes under par" .)
