Clumsy in a purely amateurish way? (8)
I believe the answer is:
ungainly
'clumsy' is the definition.
('ungainly' can be a synonym of 'clumsy')
'in a purely amateurish way?' is the wordplay.
I cannot quite see how this works, but
'in' is found in the answer.
'a' is found in the answer.
'way?' could be 'n' (Compass direction - North) and 'n' is found in the answer.
The remaining letters 'ugly' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
(Other definitions for ungainly that I've seen before include "Lacking grace in movement" , "Clumsy or awkward, as nun gaily goes about" , "Clumsy, not coordinated" , "Clumsly, maladroit" , "Physically clumsy or maladroit" .)
