The word "astronomical" originates from Greek roots. "Astron" (star) combines with "nomos" (law or arrangement), reflecting the ancient study of celestial patterns as governed laws. The suffix "-ical" forms an adjective, originally meaning "pertaining to the laws of the stars." Over time, its informal sense of "immense" arose from the vast scales observed in astronomy.
