Nonschool → It is formed from "non-" (meaning not) and "school" (from Old English *scol*, meaning a place of learning). The word "nonschool" refers to something that is not related to or does not occur in a school setting.
Think of 'non-' meaning 'not' and 'school' as a place of learning — so 'nonschool' means not related to a place of learning.
