cite

1400–50; late Middle English < Late Latin citāre to summon before a church court; in Latin, to hurry, set in motion, summon before a court, frequentative of ciēre to move, set in motion

The English verb cite “to quote a passage; summon to appear in court, etc.” comes via Middle French citer “to summon (someone) to do something” from Latin citāre “to set in motion, rouse to action, summon, summon (an accused person) by name to appear, call on (a witness), summon (someone) for empanelment on a jury” (the Romans loved law and legal procedure).
Citāre is a frequentative verb from the simple verb ciēre “to move, call, rouse, excite, provoke (disturbances, war), call upon.” Ciēre derives from a variant stem of the Proto-Indo-European root kēi- “to set in motion, be in motion.” The Greek verb kíein “to start moving” (used only in poetry) is from the same variant.
Kī-n, another (suffixed) variant of kēi-, is the root of the Greek verb kineîn “to move, shake, drive, drive away,” with the derivative nouns kínēsis and kínēma. In English, kinesis is a term used in physiology for the movement of an organism in response to a stimulus, such as light; the English noun cinema is an expensive word for movie or movies or the movies.
