Did you know?

Trace nonpareil back to its Middle French origins and you'll find that it comes from a term meaning "not equal." Pareil itself comes from the Latin word par, which means "equal," and non- is a common prefix meaning "not." In addition to its adjectival use, nonpareil also functions as a noun referring to an individual of unequaled excellence (as in "the nonpareil of cellists") as well as to a chocolate candy disk covered with small sugar pellets.
