Formed from Late Latin binōmium + -al. The derivation of binomium is unclear. It was used by Gérard de Crémone in the 12th century. Suggested sources are the Latin nomen (“name”), the Ancient Greek νομός (nomós, “distribution, pasture”), or the Old French nom (“name”). Compare binomy and binominal, as well as the French binôme.
