kinesics

Learned borrowing from Ancient Greek κῑ́νησῐς (kī́nēsĭs, “motion”, noun) + English -ics (suffix forming nouns denoting fields of knowledge or practice), coined by the American anthropologist Ray L. Birdwhistell (1918–1994) in his work Introduction to Kinesics (1952) (see the quotation). Κῑ́νησῐς (Kī́nēsĭs) is derived from κῑνέω (kīnéō, “to set in motion, move”) (from Proto-Indo-European *ḱey- (“to be lying down; to settle”)) + -σῐς (-sĭs, suffix forming abstract nouns or nouns of action, process, or result). Compare kinesia and kinesic.
