Building trust with cure arranged (9)
I believe the answer is:
structure
'building' is the definition.
(I've seen this before)
'trust with cure arranged' is the wordplay.
'with' means one lot of letters go next to another.
'arranged' indicates anagramming the letters (letters rearranged).
'trust' after 'cure' is 'curetrust'.
'curetrust' anagrammed gives 'STRUCTURE'.
(Other definitions for structure that I've seen before include "make-up" , "Building or organised arrangement" , "Building; framework" , "Edifice" .)
