simplification

Etymology

It is borrowed from French simplification,^[2][3][4][5] a French word first recorded in 1470, originally in religious contexts,^[2] from Medieval Latin simplificātiō (13th century), formed from simplificō (“to simplify”) and the suffix -iō.^[2] Etymonline allows that it may instead have been formed in English from simplify,^[3] and Merriam-Webster derives it from the Medieval Latin past participle simplificātus with the English suffix -ion.^[6][7] The Medieval Latin verb is formed from Latin simplex (“simple”) and the combining form of faciō (“to make”).^[3] The OED notes that the later meanings of the English noun were shaped by that verb.^[2]

Earliest recorded meaning

In spiritual and religious writing, the bringing of the soul to a state of simplicity, unity or purity: 1646, in a translation of Benet of Canfield's Bright Starre.^[2] The 1989 edition of the OED had 1688 as the first date,^[8] Etymonline dates the word to the 1680s,^[3] and the Shorter Oxford to the late 17th century.^[4]

Semantic evolution

The religious sense, borrowed with the French word, is not recorded after 1688.^[2] From 1751 the noun meant the making of something less complex or elaborate, or easier to do, under the influence of the verb simplify,^[2] which had itself come to mean "make easier to do" in 1759.^[3] By 1799 a simplification could also be the result, a simplified account or representation.^[2] Mathematicians used it from 1811 for reducing an equation or expression to an easier form,^[2] and in logic it has named, since Russell's Principles of Mathematics (1903), the rule that from two propositions asserted together the first may be inferred.^[2][4] In art it also means leaving out superfluous detail, in the direction of abstraction.^[6]
