Unstudied → It is formed from "un-" (meaning not) and "studied" (from Latin "studium", meaning zeal or application). The word "unstudied" means not having been studied or lacking in careful examination or attention.
Think of 'not' ('un-') having been 'applied' or 'examined' ('studied') — that's why unstudied means something that hasn't been carefully looked at.
