coffee [coffee 词源字典]: coffee: [16] The word coffee first reached us in a form which we would now recognize in the 17th century, probably via Italian caffè. It is ultimately, however, of Middle Eastern origin, and the earliest spellings recorded in English reflect this: chaoua, cauwa, kahue, cahve, etc are modelled closely on Turkish kahveh and its source, Arabic qahwah.

Where the Arabic word came from is not known for certain: probably it is based in some way on Kaffa, the name of an area in the south Abyssinian highlands from which the coffee tree is said to originate, but it has also been claimed to have signified originally some sort of wine. Café [19] comes of course from French café, whose source was Italian caffè. From the French word was derived caféine, from which English gets caffeine [19], while Spanish café produced cafetero ‘coffeeseller’, source of English cafeteria [20].

toffee: toffee: [19] Toffee is one of the mystery words of English. It is an alteration of an earlier taffy [19] (still current in American English), but where that came from is not known. The early 19thcentury spelling toughy suggests that it may have been derived from tough, in allusion to the sweet’s texture, but it is probably only a later folk-etymologizing rationalization. Another possibility is that it came from tafia ‘rumlike drink made from molasses’ [18], an alteration of ratafia [17], which was of West Indian Creole origin.
