Unschooled → It is formed from "un-" (meaning not) and "schooled" (from Old English "scolian", meaning to educate or teach). The word "unschooled" means not educated or lacking formal schooling.
Think of 'not' ('un-') being added to 'educated' ('schooled') — that's why unschooled means lacking education.
