napkin: [15] Latin mappa meant ‘cloth’ (it is the source of English map). As it passed into Old French its m became transformed into an n, producing nappe. This was borrowed into English as the long-defunct nape ‘cloth’, which, with the addition of the diminutive suffix -kin, has bequeathed napkin to modern English. The abbreviation nappy dates from the early 20th century. From derivatives of Old French nappe English also gets apron and napery [14]. => apron, map[napkin etymology, napkin origin, 英语词源]
