Rancher → The word is derived from 'ranch' (from Spanish 'rancho', meaning a small farm or dwelling) and the suffix '-er' (meaning a person who). A rancher is a person who operates or works on a ranch.
Think of someone who works on a 'small farm' ('rancho') — the '-er' just means a person. A rancher is someone who manages a ranch.
