History

Etymology

From Middle English affect, from Latin affectus, adfectus (“a state of mind or body produced by some (external) influence, especially sympathy or love”), from afficere (“to act upon, influence”).

From Middle English affecten, from Latin affectāre, from Latin affectus, the participle stem of Latin afficere (“to act upon, influence, affect, attack with disease”), from ad- + facere (“to make, do”). By surface analysis, af- + Latin -fect.

From Middle English affecten, from Anglo-Norman affecter (“strive after”), Middle French affecter (“feign”), and their source, Latin affectāre (“to strive after, aim to do, pursue, imitate with dissimulation, feign”), frequentative of afficere (“to act upon, influence”) (see Etymology 1, above).
