clueless
UK: ˈkluːləs | US: ˈkluːləs
adj. lacking knowledge or understanding; unaware
adj. foolish or incompetent
The word "clueless" combines "clue" (from Old English cleowen, meaning "ball of thread," later evolving to mean "guide or hint" from the myth of Theseus using a thread to navigate the Labyrinth) with the suffix "-less" (Old English -lēas, meaning "without"). Originally, "clue" symbolized guidance, so "clueless" literally meant "without guidance." Over time, it shifted to describe someone lacking awareness or competence, often humorously or critically.
