Settler → It is formed from "settle" (from Old English *setlan*, meaning to cause to sit or to establish) and "-er" (meaning a person who). A settler is a person who establishes a home or community in a new place.
Think of someone who 'establishes' ('settle') a new home — the '-er' just means a person. A settler is someone who makes a new place their home.
