Etymology

From Late Middle English non-parail (“unparalleled, nonpareil”) [and other forms], from Middle French nonpareille, nonpareil (“unparalleled”) (obsolete), from non- (prefix meaning ‘not’) + pareil (“alike, like, same”). Pareil is derived from Old French pareil, from Late Latin pāriculus (“equal; like; of a number: even”), from Latin pār (“equal; like; of a number: even; suitable”) + -culus (a variant of -ulus (suffix forming diminutives)). Doublet of umpire. Noun sense 4 (size of type standardized at 6-point) is usually taken to derive from the attractive type cut by the brothers Giovanni and Gregorio De Gregori (fl. 1482–1503 and 1496–1527 respectively) for their 1498 edition of the divine offices in Venice; it was for a long time the smallest-sized type in use.
