<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">colonise</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I know that colonise is a more specific form of settle)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for settle that I've seen before include "Resolve - to pay one's debts" , "Find a home" , "Resolve; alight" , "rest > put in order" , "Come to an agreement about something" .)
