Show remorse having sent off one right winger (5)
I believe the answer is:
egret
'winger' is the definition.
(type of bird)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for egret that I've seen before include "young bird" , "Greet (anag) -- wading bird" , "Seabird" , "Water-bird, has plume" , "White wading bird" .)
