Orderliness (8)
I believe the answer is:
tidiness
'orderliness' is the definition.
(I know that tidiness is a type of orderliness)
This is the entire clue.
(Other definitions for tidiness that I've seen before include "good order" , "Insisted on neatness." , "Quality of neatness and orderliness" , "sense of order" , "Orderly quality" .)
