Word Origin & Etymology

Borrowed from Old French 'nombre', which derives from Latin 'numerus' meaning 'a quantity, count, or division', ultimately traced to the Proto-Indo-European root '*nem-' meaning 'to assign, allot, or take'. The silent 'b' was inserted in Middle French and Middle English by natural phonetic transition between 'm' and 'r'.
