geniculationn.

Brit.

/dʒᵻˌnɪkjᵿˈleɪʃn/, U.S.

/dʒəˌnɪkjəˈleɪʃən/

Origin: A borrowing from Latin. Probably also partly formed within English, by derivation. Etymons: Latin geniculation- , geniculatio ; geniculate adj., -ion suffix¹.

Etymology: Originally (in sense 1) < post-classical Latin geniculation-, geniculatio act of kneeling (late 2nd or early 3rd cent. in Tertullian) < geniculat- , past participial stem of geniculare to bend the knee (see geniculate v.) + classical Latin -iō -ion suffix¹. In later use probably independently < geniculate adj. + -ion suffix¹; compare later geniculate v., geniculated adj.With sense 2a perhaps compare German †Geniculation (1769 in a work on animal fossils).

†1. The action or an act of kneeling in worship; genuflection. Obsolete.
