Origin & History of “number”

The etymological notion underlying the word number is probably ‘distribution’. Its ultimate source, Latin numerus, may have been related to Greek némein ‘deal out, distribute’ (source of English nemesis and related to nomad). Numerus passed into Old French as nombre (subsequently borrowed by German as nummer), and English acquired it via Anglo-Norman numbre. Derivatives of Latin numerus to have reached English include enumerate (17th c.), numeral (16th c.), numerate (20th c.), numerical (17th c.), and numerous (16th c.).
