Nafkin
Decades ago, an in-law of mine bought a box of Lucky Wood* silver spoons which included a handsome, helpful, and hand-bound pamphlet:
Look at that stylized cutlery trio! Even as the trees that whisper round a temple become soon dear as the temple's self, so does the spoon—or rather, the knife; I love the way they've solved that "one of these things is not like the other" problem.
But here's what interested me most:
Nafukin. Not napukin: nafukin. This is not an aberration; it can be found in, for example, MIYAZAWA Kenji 宮沢賢治's "Chūmon no ōi ryōriten" (注文の多い料理店, "The restaurant of many orders")
「早くいらつしやい。親方がもうナフキンをかけて、ナイフをもつて、舌なめずりして、お客さま方を待つてゐられます。」
二人は泣いて泣いて泣いて泣いて泣きました。
"Hurry up! The boss has already put on his nafkin, picked up his knife, and started licking his chops; he can't wait to see you."
The two gentlemen cried and cried and cried and cried and cried.
Both variants remain in use in modern Japanese, too. This dude claims that nafukin is mostly a primary/secondary school thing, and possibly an attempt to separate the napkin-for-blood/napkin-for-food concepts, in order to shield delicate children from the harsh realities of biology. This may be so, but googling reveals that this semantic differentiation is only maintained sporadically (mostly on blog posts about this very topic) out in the real world.
It isn't usual for /p/ to become /f/ in Japanese loanwords from English, so what caused it here? Rogue strain of Grimm's Law, perhaps introduced by an escaped Prussian circus monkey in the Meiji period? Prehistoric Japanese sound shifts revived and enraged by atomic testing?
No: Word on the streets is that it was interference from the Sino-Japanese word fukin 布巾, conveniently meaning "scrap of cloth."
(Fun fact: As the guy linked above points out, ナ布巾 can be visually rearranged into ナナ巾巾.)
(What do you mean that wasn't fun?)

Matt,
Amusing and informative post. Thanks!
