<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">colonists</span>' is the definition.<br/ ><span class="explanation-format__explanation">('settler' can be a synonym of 'colonist')</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for settlers that I've seen before include "Colonists" , "who pay their bills?" , "Trestles for pioneers" , "Immigrants" , "Pioneers, homesteaders" .)
