Nonintellectual → It is formed from "non-" (meaning not) and "intellectual" (from Latin "intellectus", meaning understanding or the ability to think). The word "nonintellectual" means not related to or not involving intellectual activity or thought.
Think of 'not' ('non-') related to 'understanding' ('intellectus') — that's why nonintellectual means not involving intellectual thought.
