Settled some prim cod arrangement (11)
I believe the answer is:
compromised
'settled' is the definition.
(compromising is a kind of settling)
'some prim cod arrangement' is the wordplay.
'arrangement' indicates anagramming the letters.
'some'+'prim'+'cod'='someprimcod'
'someprimcod' anagrammed gives 'COMPROMISED'.
(Other definitions for compromised that I've seen before include "Endangered through recklessness" , "Being exposed to disrepute" , "Placed in an invidious position" , "made concessions" , "reduced in quality" .)
