Relating to the cosmos, universe, or space; of or pertaining to the whole universe rather than just Earth.
From Greek kosmos 'universe, world order' plus -ical (adjective suffix). An archaic or poetic variant of 'cosmic' that was more common before the 20th century.
While 'cosmical' is rarely used today, poets and older texts preferred it over 'cosmic'—it has an almost mystical, grandiose feel compared to the modern form.
