satisfy: [15] Etymologically, satisfy means ‘make enough’. It comes, via Old French satisfier, from Latin satisfacere ‘satisfy, content’, a compound verb formed from satis ‘enough’ (a relative of English sad, sated, and saturate, and source of English satiate). The derived noun satisfaction reached English well over a century before the verb, in the specialized ecclesiastical sense ‘performance of penance’.
