50% of capital invested in modest settlement (6)
I believe the answer is:
'settlement' is the definition.
(I know that settlement can be written as colony)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for colony that I've seen before include "New settlement abroad" , "Country controlled by another's settlers" , "Settler's territory" , "Beavers' group" , "Group of animals or plants living together" .)
