From Middle English nombre. Middle English number, nombre, numbre, noumbre, from Anglo-Norman noumbre, Old French nombre, from Latin numerus (“number”), ultimately from Proto-Indo-European nem- (“to distribute, to give, to take”). Compare stq Nummer, Nuumer, West Frisian nûmer, Dutch nummer (“number”), German Nummer (“number”), Danish nummer (“number”), Swedish nummer (“number”), Icelandic númer (“number”). ȝetæl and rime; more at tell, tale and rhyme. Distantly related (via Proto-Indo-European) to English nim (“to take, seize”) and its Germanic cognates (e.g. German nehmen), hence also to numb.
