Papers in sets in different order (8)
I believe the answer is:
tidiness
'order' is the definition.
(I've seen this before)
'papers in sets in different' is the wordplay.
'papers' becomes 'id' (identification papers).
'in' indicates putting letters inside.
'different' indicates anagramming the letters.
'sets'+'in'='setsin'
'setsin' is an anagram of 'tiness'.
'id' placed within 'tiness' is 'TIDINESS'.
(Other definitions for tidiness that I've seen before include "sense of order" , "Insisted on neatness." , "good order" , "Orderly quality" , "Quality of neatness and orderliness" .)
