rotate

Etymology

The verb is borrowed from Latin rotātus, the past participle of rotō (“to cause to spin, revolve, whirl round”),^{[2][3][4][5][6]} from rota (“wheel”),^[2][6][3][7] with the English suffix -ate.^[2][4] The OED suggests that it may have been formed after rotation,^[2] and Etymonline and Barnhart take it as a back-formation from that noun.^[8][9][10] The American Heritage Dictionary traces the Latin noun to the Indo-European root Proto-Indo-European *ret- (“to run, roll”).^[6] The botanical adjective meaning wheel-shaped comes from rotatus, recorded in post-classical Latin by 1700, also from the Latin word for wheel with the suffix -ātus.^[2][11][3]

Earliest recorded meaning

Of a thing, to turn about a centre or an axis inside it: 1757, in a translation of the Marquis d'Argens's “Philosophical Visions”.^[2][3] Earlier still, the past participle was used in English in the sense "revolved", in G. Ripley's “Compend of Alchemy” (before 1500), a use the OED marks as obsolete.^[2]

Semantic evolution

The first dates differ: the OED and Merriam-Webster record the verb from 1757,^[2][3] Etymonline from 1794,^[8] Barnhart from 1808,^[9][10] and Dictionary.com dates it to 1800–10.^[4] The Shorter Oxford puts it in the late 17th century, earliest in the participle rotating.^[11] The transitive use, to make a thing spin, followed in 1777,^[2] and Etymonline finds it by 1823.^[8] From the idea of a regular cycle, as in rotation of office, the verb came to mean moving people or things into and out of a position in turn (1800), and of people, taking turns (1841).^[2] In farming it was used of crops grown in rotation from 1836,^[2] and in the US army from 1944 of recalling a soldier or unit from combat or overseas service.^[2][11] The botanical adjective, describing a corolla whose petals spread out like the spokes of a wheel, is recorded from 1760.^[2][3][11]
