Etymology

The word "elliptical" derives from the Greek "elleiptikos" (defective or lacking), which evolved into Late Latin "ellipticus," referring to the geometric shape. The root "ellipse" originates from the Greek "elleipsis" (a falling short), as an ellipse is a "defective" circle that falls short of being perfectly round. The suffix "-ical" (from Latin "-icalis") forms adjectives, giving "elliptical" its modern meanings of oval-shaped or linguistically concise/vague.
