n. the line where the earth's surface and the sky appear to meet

The word "horizon" originates from the Greek "horizōn (kyklos)," meaning "limiting (circle)." The morpheme "hori" derives from "horos" (boundary), and "zon" comes from "kyklos" (circle), later adapted into Latin as "horizon." The term originally described the circular boundary where the sky appears to meet the earth, reflecting ancient cosmological views. Over time, it expanded metaphorically to denote limits of perception or understanding.
