Unfrequented → It is formed from "un-" (meaning not) and "frequent" (from Latin "frequentare", meaning to visit often). The word "unfrequented" means not visited often or rarely visited.
Think of 'not' ('un-') visiting often ('frequent') — that's why unfrequented means a place that is rarely visited.
