c.1300, parchemin (c.1200 as a surname), from Old French parchemin (11c., Old North French parcamin), from Late Latin pergamena "parchment," noun use of adjective (as in pergamena charta, Pliny), from Late Greek pergamenon "of Pergamon," from Pergamon "Pergamum" (modern Bergama), city in Mysia in Asia Minor where parchment supposedly first was adopted as a substitute for papyrus, 2c. B.C.E. Possibly influenced in Vulgar Latin by Latin parthica (pellis) "Parthian (leather)." Altered in Middle English by confusion with nouns in -ment and by influence of Medieval Latin collateral form pergamentum.
