Puts up with secret arrangement (6)
I believe the answer is:
erects
'puts up' is the definition.
('erect' can be a synonym of 'put up')
'secret arrangement' is the wordplay.
'arrangement' indicates an anagram.
'secret' with letters rearranged gives 'ERECTS'.
'with' acts as a link.
(Other definitions for erects that I've seen before include "Puts up, stand or building" , "Builds, constructs" , "Put up, builds" , "Constructs, puts up" , "Secret (anag.)" .)
