undiscovered
UK: ˌʌndɪˈskʌvəd | US: ˌʌndɪˈskʌvərd
adj. not found, explored, or known; remaining hidden or unnoticed
The word "undiscovered" combines the prefix "un-" (Old English "un-," meaning "not") with the verb "discover" (from Old French "descovrir," meaning "uncover" or "reveal," itself derived from Latin "dis-" [apart] + "cooperire" [to cover]). The suffix "-ed" forms the past participle, indicating a state of being. Thus, "undiscovered" literally means "not having been uncovered or found," reflecting its modern usage for things remaining hidden or unknown.
