agitation

Etymology

It is borrowed from Middle French agitation and directly borrowed from Latin agitātiō (“violent moving, shaking, disturbance”),^[2][3][4] a noun formed from agitātus, the past participle of agitō (“to set in motion, move to and fro”), with the suffix -iō.^[2][5] The Latin verb is the frequentative of agō (“to set in motion, drive, do”),^[5][6][7] from Proto-Indo-European *ag- (“to drive, draw out or forth, move”).^[5][6] Barnhart takes the English noun from Latin alone.^[8] The OED records the French noun from before 1356 for the state of being moved to and fro, and notes that its sense "disturbance of the mind" appears in French only in 1640, later than in English.^[2] It compares agitación, agitazione and Agitation, all from Latin.^[2] The Latin word was glossed Old English unstilnis in Old English.^[5]

Earliest recorded meaning

The state of being moved backwards and forwards; commotion, disturbance: 1547, in C. Langton's treatise on physic.^[2] Merriam-Webster's first known use is about 1550, for the now obsolete sense "motion, activity",^[3] Etymonline dates the noun to the 1560s in the sense "debate, discussion",^[5] and Barnhart to 1596, in Shakespeare's Merchant of Venice.^[8]

Semantic evolution

Etymonline explains the early sense "debate, discussion" as a mental tossing of a matter to and fro,^[5][4] and the OED records it, with the urging of a plan and scheming, from 1600 in the Merchant of Venice.^[2] The sense of mental disturbance or nervous excitement is in the OED from about 1555,^[2] though Etymonline dates it only to 1722.^[5] The action of shaking or stirring something is recorded from 1569,^[2] and a general sense "physical motion, activity" was used from 1573 to 1705.^[2][4] Johnson (1755) defined it first as the act of moving or shaking anything, then as the state of being moved or agitated.^[9] During the English Civil War it was also the activity of an agitator, one of the soldiers' delegates.^[2] The political sense, the stirring up of public concern to bring about action, dates from 1829 in the OED and 1828 in Etymonline,^[2][5] after a sense "social unrest" from 1769;^[2] the OED compares its later socialist and communist use with agitprop.^[2] In South Asia an agitation has been a public demonstration or a strike since 1913.^[2]
