"Crypto-Judaism is the secret adherence to Judaism while publicly professing to be of another faith; practitioners are referred to as \"crypto-Jews\" (origin from Greek kryptos - \u03BA\u03C1\u03C5\u03C0\u03C4\u03CC\u03C2, 'hidden'). The term crypto-Jew is also used to describe descendants who maintain some Jewish traditions of their ancestors while publicly adhering to other faiths."@en . . .
