Colonist, one footing the bill? (7)
I believe the answer is:
settler
'colonist' is the definition.
(I know that colonist can be written as settler)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for settler that I've seen before include "new inhabitant" , "Early colonist" , "Person who moves into an uninhabited country" , "One colonising new area" , "New colonist" .)
