ordinateur m (plural ordinateurs)[1]

Etymology

It is borrowed from Latin ōrdinātor (“one who sets in order, regulator”), a word of Imperial Latin formed on the supine of ōrdinō (“to put in order”) (whence ordonner), from ōrdō (“order”).[2][3][4][1] The computing sense was proposed by the philologist Jacques Perret in a letter of 16 April 1955, in answer to IBM France, which found calculateur too narrow for these machines;[1][5] the Grand Robert calls it a learned derivative of the Latin noun or of ordination, made at IBM France's request (1954) to replace the anglicism English computer.[6] Rey stresses that it was formed after the first sense of the Latin, “to put in order”, rather than the idea of calculating.[3] Perret had suggested a feminine form, ordinatrice, but the masculine prevailed.[5]

The same word form had existed since 1491 as a learned borrowing of the Latin word, for one who institutes or orders something, later for one who confers holy orders: the Grand Robert treats it as a separate headword, numbered 1.[2][3][6]

Earliest recorded meaning

Before the computer, the word is first recorded in 1491, in La mer des histoires, of Christ as the one who instituted baptism.[2][3] In the computing sense the TLFi and Rey date it to 1956, while the Grand Robert gives 1955.[2][3][6]

Semantic evolution

The old word stayed rare: around 1600 Pasquier used it for one who manages public affairs, Boiste (1823) still listed it as “one who puts in order”, and 19th- and 20th-century dictionaries kept the liturgical sense “one who confers an ecclesiastical order” (1703, Bossuet).[2][3] As an adjective “that puts in order” it is dated, ordonnateur being preferred.[2][7]

The computing word, against expectation, won over the anglicism computer and its adaptation computeur.[3] It gave micro-ordinateur (1971), clipped as micro (1974), mini-ordinateur (1974) and, with a combining form ordino-, ordinogramme (1968); in familiar speech it is shortened to ordi.[3][7]
