Clearly insisted on a spruce condition (8)
I believe the answer is:
tidiness
'condition' is the definition.
(tidiness is a kind of condition)
'clearly insisted on a spruce' is the wordplay.
'insisted' anagrams to 'TIDINESS'.
But, I am unsure how this is indicated.
Can you help me to learn more?
(Other definitions for tidiness that I've seen before include "Orderly quality" , "good order" , "sense of order" , "Insisted on neatness." , "Quality of neatness and orderliness" .)
