Meaning

  1. adjectivered
    qui gregem armentorum emere vult, observare debet primum, ut sint eae pecudes aetate potius ad fructos ferendos integrae quam iam expartae; ut sint bene conpositae, [...] colore potissimum nigro, deinde rōbeō, tertio helvo, quarto albo: mollissimus enim hic, ut durissimus primus. de mediis duobus prior quam posterior in eo prior, utrique plures quam nigri et albi.1937 translation by W. D. Hooper and H. B. Ash One who wishes to buy a herd of cattle should be careful to have animals of such an age that they are sound for bearing calves rather than those which have already reached the age of barrenness. They should be well formed, …. The best colour is black, next red, then dun, and then white; for those of the last mentioned colour are most delicate, and those of the first most hardy. Of the other two colours the first is preferable to the second, while both are more common than the black and the white.116 BCE – 27 BCE, Marcus Terentius Varro, Rerum rusticarum 2.8
    Robum rubro colore et quasi rufo significari, ut bovem quoque rustici appellant, manifestum est.c. 2nd century, Sextus Pompeius Festus, De Verborum Significatione

Origins

Uncertain. According to Sihler, the term may be a borrowing from Umbrian, where—unlike Latin—the regular outcome of Proto-Italic *-ew- or *-ow- was ō. De Vaan suggests that the term ultimately derives from Proto-Italic *rouðos, though he suggests that the long ō is probably a dialectal feature.
