Etymology

The word "shady" originates from the noun "shade," which traces back to Old English sceadu (shadow, darkness) and Proto-Germanic skadwaz. The suffix "-y" (from Old English -ig) was added to form an adjective meaning "full of shade." Over time, the term evolved metaphorically to describe things or people that are "concealed" or "morally dubious," reflecting the association of darkness with secrecy or dishonesty.
