Pronunciation

  • IPA: UK /ˈsɜː.fɪs/, US /ˈsɝː.fɪs/[1]

Etymology

It is borrowed from Middle French surface (“outermost boundary, outside part”),[2][3] from sur- (“above”) and face,[2][3] modelled on Latin superficiēs (“surface, upper side, top”),[2][3][4] the source of superficial.[2] The verb is from the noun.[2][3]

Earliest recorded meaning

The outer boundary of a body: 1611, in Cotgrave's French–English dictionary,[3][5] and the 1610s in Etymonline.[2] Merriam-Webster dates it to about 1600.[6]

Semantic evolution

The top of the ground is a surface from 1612, and of water or another liquid from 1625.[5] In geometry, an extent of only two dimensions, it is from 1658.[5] The figurative sense, “outward appearance”, is by 1725.[2][5] The adjective, “on the surface”, is from the 1660s,[2][3] and “superficial” from 1828.[2] Surface tension is so called by 1876[2] and surface-to-air missiles by 1950.[5][2] The verb meant “to give a smooth surface to” from 1778,[5][3] “to bring to the surface” from 1885, and “to come to the surface”, as of a submarine, from 1898.[2][3]
