Field event becoming more non-professional? (6)
I believe the answer is:
hammer
'field event' is the definition.
(hammer is a kind of field event)
'more non-professional?' is the wordplay.
I cannot really understand how this works, but
'more' could be 'm' and 'm' is located in the answer.
'non professional?' could be 'ham' and 'ham' is found in the answer.
The remaining letters 'er' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
'becoming' acts as a link.
Can you help me to learn more?
(Other definitions for hammer that I've seen before include "Clawed tool?" , "Things sold at auction come under the . . . . . ." , "Beat repeatedly; tool" , "Tool for nails" , "Nail banger" .)
