Corner Germanic invader (5)
I believe the answer is:
angle
I believe this is a double definition.
'corner' is the first definition.
(I've seen this in another clue)
'germanic invader' is the second definition.
(I've seen this before)
(Other definitions for angle that I've seen before include "Early settler" , "A way of approaching" , "Point of view - fish" , "Gradient" , "Right, acute or obtuse" .)
