Kafka
If you’ve ever read the works of Franz Kafka, you’ve perhaps been a little bit disappointed: For all the promotion, they’re a bit short & simple, and often even unfinished. If Kafka was really a crapto-aristocrat from a wealthy family, it would explain this over-promotion. His name may be a hint: Slavic kavka means “jackdaw”, but kovak (from kovati + -ak) means “malleable”, but could also mean “mint-er” & “coin-er”, which could point to a family of bankers. The general meaning is “forgery”, which is a synonym for “fake” in English (though not in Slavic).
Slavic kavka = jackdaw; kovak, kovati = malleable, forge, mint, coin, plot
