I'd cede arrangement and settle (6)
I believe the answer is:
decide
'settle' is the definition.
(I know that settle can be written as decide)
'i'd cede arrangement' is the wordplay.
'arrangement' indicates an anagram.
'id'+'cede'='idcede'
'idcede' is an anagram of 'DECIDE'.
'and' acts as a link.
(Other definitions for decide that I've seen before include "Determine - settle" , "Resolve; give judgement" , "Adjudicate" , "Judge" , "Resolve or give a judgment" .)
