schematic

Etymology

It is borrowed from New Latin schēmaticus,^[2][3][4][5] from the stem of schēma (“shape, figure, manner”),^[3][4][6] from Ancient Greek σχῆμα (skhêma, “form, figure”).^[2][3] The Shorter Oxford also allows a formation within English from the stem of scheme,^[7] and Etymonline treats it as a formation with -ic on the Latin stem of scheme.^[6] The Greek noun comes from the root of ἔχω (ékhō, “to have, hold”),^[2][6] from Proto-Indo-European *segh- (“to hold”).^[2][6][8] Late Greek had σχηματικός (skhēmatikós) only in the sense "false, pretended", from the Greek noun in the sense "appearance",^[2] and the OED compares German schematisch.^[2]

Earliest recorded meaning

Relating to a scheme or schema, or corresponding to something according to a scheme: 1701, in T. Beverley's Grand Apocalyptic Question.^[2][3][6]

Semantic evolution

The Shorter Oxford notes that the first, rare sense was "corresponding to something in accordance with a scheme", and that the word came to mean "of the nature of a diagram".^[7][2] In the 19th century it took on special uses: of logical figure (before 1856, in Sir William Hamilton's lectures), in art of following a conventional type (1868, George Eliot), and of what is shaped by a preconceived system (1894).^[2] The noun, short for schematic diagram, is dated by Etymonline to 1910^[6] and by the OED and Merriam-Webster to 1929, in a book on private telephone exchanges;^[2][3] it is now used especially of electrical and electronic circuits.^[9][10] The related schematical is from the 1670s.^[6]
