Middle English, from Latin meteorum, from Ancient Greek Î¼ÎµÏ„ÎÏ‰ÏÎ¿Î½ (meteÅron), from Î¼ÎµÏ„ÎÏ‰ÏÎ¿Ï‚ (meteÅros, “raised from the ground, hanging, lofty"), from Î¼ÎµÏ„Î¬ (meta, “in the midst of, among, between") (English meta) + á¼€ÎµÎ¯ÏÏ‰ (aeiro, “to lift, to heave, to raise up").
Original sense of “atmospheric phenomenon" gave rise to meteorology, now restricted to extraterrestrial objects burning up as they enter the atmosphere.
