Etymology: Eleven itself is an old word with a plain, literal core: its Old English form "endleofan" came from roots meaning "one left" (one left over after counting to ten), so the number was built by adding one to ten. That sense of "leftover" survives only in the word's history, not in its use today. The Old English word passed through Middle English "ellevene" and reached its modern form in English. The "-fold" ending is the more transparent part. It comes from an Old English and Germanic root meaning "fold" in the sense of a layer or multiple, so "-fold" signals multiplication: "twofold" means twice, "tenfold" ten times. Attaching it to "eleven" gives the straightforward meaning of multiplying by eleven.

Synonyms: eleven times, 11-fold
