Well-ordered condition of pure in spirit? (8)
I believe the answer is:
neatness
'well-ordered condition' is the definition.
'pure in spirit?' is the wordplay.
'pure' becomes 'neat' (I've seen this before).
'in spirit?' becomes 'ness' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'neat'+'ness'='NEATNESS'
'of' is the link.
Can you help me to learn more?
(Other definitions for neatness that I've seen before include "Orderliness" , "Tidiness" , "well-tended condition" , "condition of the pure in spirit?" , "Tidy quality" .)
