If obtuse, can never be right (5)
I believe the answer is:
angle
'right' is the definition.
The answer and definition can be both to do with motion as well as being verbs in their base form.
Perhaps there's an association between them I don't understand?
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for angle that I've seen before include "possibly obtuse" , "Try to catch" , "Gradient" , "Point of view - associated with Saxon" , "Ancient German, fish" .)
