Note 7 — ON THE INTELLECTUAL SUPERIORITY WHICH MAN HAS ACQUIRED BY SPEECH, AND THE POSSESSION OF THE HAND.
Reading edition
It is not uninteresting to examine the contrivances that have been resorted to, in order to express the number eleven. The Greeks had ενδεχα [Greek: endeka], one (and subaudit) ten; the Romans undecem; and a similar adoption has been employed by the southern nations of Europe. The northern people expressed eleven, by one left (after ten, subaudit.) thus Caxton states his Recuyels of Troy to have been "ended and fynished in the holy cyte of Colen, the 19th day of Septembre, in the yere of our sayd Lord God, a thousand four hundred sixty and enleven." En, in old English, means one, and leven is the past participle of, to leave, formerly written leve.
