More neat (6)
I believe the answer is:
tidier
'more neat' is the definition.
('tidy' can be similar in meaning to 'neat')
This is the entire clue.
(Other definitions for tidier that I've seen before include "Trigger" , "More neat and orderly" , "More presentable" , "'Neater, in better order (6)'" , "More methodical" .)
