The adjective is a learned borrowing from Latin ōre rotundō (“with a round mouth; hence, clear; loud”) (whence English ore rotundo), possibly influenced by rotund (“having a curved, round, or spherical shape; (figurative) of sound: full and rich”). Ōre rotundō is composed of ōre (the ablative singular of ōs (“mouth”), ultimately from Proto-Indo-European *h₁óh₃s (“mouth”)) + rotundō (the ablative singular of rotundus (“circular, round”) (possibly from rota (“wheel”) (ultimately from Proto-Indo-European *Hreth₂- (“to run”)) + -undus (suffix forming adjectives)).
The noun is derived from the adjective.
