assentation

[Lat. a entatio = flattering a ent, pretended concurrence with everything that a person says; a entor = to a ent habitually, with insincerity; as sent i or = to a ent to: ad to, and sentio = to feel.] Hypocritical a ent to everything which another says; pretended concurrence in every opinion, however absurd, which he broaches; the implied object being, for the most part, to flatter him for selfish ends, or at least to avoid giving him offence. "It is a fearful presage of ruin when the prophets conspire in a entation."- Bishop Hall .
