fatuus

Latin

Etymology

Uncertain. Maybe from dialectal Proto-Indo-European *bʰat-. (See also battuō.) More likely, a derivative of *bʰeh₂- (“to speak”), particularly an abstract noun *bʰh₂-tu- (“speech”); thereby related to for.

According to one hypothesis, Fatuus was an alternative name of the god Faunus, who predicted the future.
