English composer brought back tailless bird (5)
I believe the answer is:
eagle
'english composer brought back' is the definition.
I can't tell whether this definition defines the answer.
'tailless bird' is the wordplay.
'tailless' means to remove the last letter.
'bird' becomes 'eaglet' (I have seen 'Young bird ' mean 'eaglet' so perhaps 'bird' could also mean 'eaglet').
'eaglet' with its final letter taken off is 'EAGLE'.
Can you help me to learn more?
(Other definitions for eagle that I've seen before include "Avian symbol of power" , "Old comic" , "two strokes fewer?" , "ten-dollar coin" , "Erne, perhaps" .)
