binomial
From Wiktionary, the free dictionary
Etymology
Formed from Late Latin binōmium + -al. The derivation of binōmium is unclear. It was used by Gerard of Cremona in the 12th century. Suggested sources are the Latin nōmen (“name”), the Ancient Greek νομός (nomós, “distribution, pasture”), or the Old French nom (“name”).[1] Compare binomy and binominal, as well as the French binôme. By surface analysis, bi- + -nomial.
