Germanic Briton, crook (5)
I believe the answer is:
angle
I believe this is a double definition.
'germanic briton' is the first definition.
(the Angles were a historical people of Britain)
'crook' is the second definition.
(I've seen this before)
(Other definitions for angle that I've seen before include "Germanic invader" , "Fish; viewpoint" , "Fish with a rod" , "Ancient German, fish" , "member of tribe" .)
