rudiment

Etymology

It is borrowed from Latin rudīmentum (“first lesson, early training, first experience”),^[2][3][4] and Etymonline, Barnhart, Hoad and the Shorter Oxford allow a route through French as well, by way of Middle French rudiment.^[5][6][7][8] The Latin noun is formed from rudis (“rough, unformed; unlearned, untrained”), the source of rude,^[2][6][9] with the suffix -mentum,^[2][10] on the pattern of elementum (“element”).^[8][11] Klein and Etymonline call the origin of the adjective uncertain.^[9][5] The OED compares rudiment, recorded in the sense of first principles from 1545, rudiment (14th century), rudimento (1492) and rudimento (1538).^[2]

Earliest recorded meaning

In the plural, the first principles of a subject: 1534, in W. Marshall's translation of Erasmus.^[2][12] Barnhart gives 1548, and Etymonline the 1540s.^[6][5]

Semantic evolution

The Latin word had already moved from a first lesson to the initial stage of something by the 2nd century AD.^[2] In English the singular, a first principle or first step in learning, appears in 1548, in Udall's translation of Erasmus.^[2][6] From 1557 the word was used in Bible translations, especially at Galatians 4:3, where other versions have "elements of the world".^[2] In 1566, in Painter's Palace of Pleasure, the plural is used for the imperfect beginnings of a thing, whether material or not,^[2][5] and the singular follows in 1625.^[2] The biological use, for an undeveloped precursor of an organ or leaf, is recorded from 1588, in a discourse on peppers,^[2] though the Shorter Oxford dates it to the early 17th century.^[8] Johnson (1755) defined it first as "the first principles; the first elements of a science".^[13] A verb, to be rudimented in a subject, was used from 1654 to 1768.^[2] Rudiments also became the name of a class in Roman Catholic, especially Jesuit, schools (1716),^[2][8] and in the 20th century the name of the basic patterns of drumming (1919).^[2]
