Origin & History of “space”

Space comes via Old French espace from Latin spatium ‘distance, space, period’, a word of unknown origin. Its modern English application to the ‘expanse in which the universe is contained’ did not emerge until the 19th century. The Latin derived adjective spatiōsus has given English spacious (14th c.), but spatial (19th c.) was coined in English directly from Latin spatium.
