space: [13] 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 [14], but spatial [19] was coined in English directly from Latin spatium.

space (n.)youdaoicibaDictYouDict
c. 1300, "extent or area; room" (to do something), a shortening of Old French espace "period of time, distance, interval" (12c.), from Latin spatium "room, area, distance, stretch of time," of unknown origin (also source of Spanish espacio, Italian spazio).

From early 14c. as "a place," also "amount or extent of time." From mid-14c. as "distance, interval of space;" from late 14c. as "ground, land, territory; extension in three dimensions; distance between two or more points." From early 15c. as "size, bulk," also "an assigned position." Typographical sense is attested from 1670s (typewriter space-bar is from 1876, earlier space-key, 1860).

Astronomical sense of "stellar depths, immense emptiness between the worlds" is by 1723, perhaps as early as "Paradise Lost" (1667), common from 1890s. Space age is attested from 1946. Many compounds first appeared in science fiction and speculative writing, such as spaceship (1894, "A Journey in Other Worlds," John Jacob Astor); spacecraft (1928, "Popular Science"); space travel (1931); space station (1936, "Rockets Through Space"); spaceman (1942, "Thrilling Wonder Stories"). Space race attested from 1959. Space shuttle attested by 1970.
Space isn't remote at all. It's only an hour's drive away if your car could go straight upwards. [Sir Fred Hoyle, "London Observer," 1979]
