The way it's arranged is capital (5)
I believe the answer is:
asset
'is capital' is the definition.
(thesaurus)
'the way it's arranged' is the wordplay.
'the way' becomes 'as' (I've seen this in other clues).
'it's arranged' becomes 'set' (similar in meaning).
'as'+'set'='ASSET'
(Other definitions for asset that I've seen before include "Useful thing or person" , "Valuable item" , "Valuable thing" , "One bringing benefit" , "Plus point" .)
