Flapper somewhat consoles sick cider-drinking revolutionary (10)
I believe the answer is:
dickcissel
'flapper' is the definition.
(type of bird, something which flaps its wings)
'somewhat consoles sick cider-drinking revolutionary' is the wordplay.
'drinking' says the answer is hidden in the clue (the clue has drunk in the answer).
'revolutionary' says the letters should be written in reverse.
'lessickcid' can be found hidden inside 'somewhat consoles sick cider'.
'lessickcid' in reverse letter order is 'DICKCISSEL'.
(Another definition for dickcissel that I've seen is " Bird".)
