Tidy, orderly (4)
I believe the answer is:
neat
This clue is a double definition.
'tidy' is the first definition.
(synonyms)
'orderly' is the second definition.

(Other definitions for neat that I've seen before include "Tidy, well-organised" , "Tidy - undiluted" , "Steers" , "Tidy and dapper" , "descendant of 19 [AUROCHS]" .)
