Payment for a colony (10)
I believe the answer is:
settlement
This clue is a double definition.
'payment' is the first definition.
(thesaurus)
'colony' is the second definition.
(I know that colony can be written as settlement)
'for a' acts as a link.
(Other definitions for settlement that I've seen before include "deal" , "Resolution" , "Community; agreement" , "Working out" , "Hamlet - conclusion" .)
