Definition of affectually in US English:



  • Originally and chiefly Psychology and Sociology. By, with reference to, or as regards feelings, emotion, or mood.


Late Middle English (in an earlier sense). Apparently from Anglo-Norman and Middle French affectuel or its etymon post-classical Latin affectualis affectual + -ly; compare Anglo-Norman affectuelment and Middle French afectuelment, and later affectual. In 20th cent. apparently re-formed from affectual + -ly.
