superficial

Etymology

It is borrowed from Middle French superficial, also superficiel (“located at the surface”), and its source borrowed from Late Latin superficiālis (“of or relating to a surface”),^[2][3][4] formed from superficiēs (“surface, upper side, top”) and -ālis.^[2][5][6] The Latin noun is formed from super (“above, over”) and faciēs (“form, face”), the source of face.^[3][7][8] The OED notes that the French adjective is recorded from 1314, first in medicine, and that in Latin superficiālis meant "inexact" in Tertullian (early 3rd century), "relating to a surface or area" from the 6th century, and "trivial, lacking depth" in British sources from the 12th; it compares superficiale (before 1375) and superficial.^[2] Barnhart thinks the Latin word was borrowed, perhaps under the influence of the French one.^[8]

Earliest recorded meaning

Of a number, having two prime factors and so able to be pictured as a rectangle: before 1398, in John Trevisa's translation of Bartholomaeus Anglicus.^[2] Barnhart dates the sense "of or relating to a surface, external" to 1392,^[8] and Etymonline gives the late 14th century, in anatomy, for "at the surface of the skin, not deep-seated".^[3]

Semantic evolution

The word first described surfaces and areas: the dimensions of a plane (from about 1450), units of area such as the superficial foot (1597), and things lying on or near the surface, including parts of the body just under the skin.^[2] The sense "not thorough, cursory" grew from the idea of not reaching below the surface:^[3] it is recorded of judgements from about 1456, in Pecock,^[2][8] and of knowledge from 1559.^[2] Etymonline finds it implied earlier, in the early 15th century, in superficially.^[3] The OED also has "trivial, insubstantial" before 1425.^[2] Of a person, "shallow, concerned only with appearances" is first recorded in 1603, in John Florio's translation of Montaigne,^[2] whose French had used superficiel this way in 1590;^[2] Ayto puts the rise of this main modern sense in the 16th century.^[7] Johnson (1755) defined it first as "lying on the surface" and then as "shallow; not profound", of knowledge.^[9] The noun, a superficial person or aspect, dates from 1579.^[5]
