Wilbur Wright's brother (7)
I believe the answer is:
orville
'wilbur wright's brother' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for orville that I've seen before include "A Wright brother, d.1948" , "One of the Wright brothers" , "- - and Wilbur Wright, aviators" .)
