Why “assentator” is a great word
ASSENTATOR — [Noun] An obsequious flatterer; a sycophant or yes-man. Borrowed from Latin assentātor, from assentārī ("to assent constantly, to flatter"). First attested in English in 1531. Unlike an "admirer," whose approval is rooted in genuine respect, or a "critic," whose role demands judgment, the assentator deals exclusively in the hollow currency of calculated, fawning accord. He is the murmured chorus of "indeed" after a tyrant's jest, the polished mirror held up to reflect only a magnified image, the silent nod that sanctifies every folly—a hollow man whose ambition is painted in the thin, reflective veneer of borrowed light.
