Zen (zn) KEY
Japanese zen, from Chinese (Mandarin) chán, meditation, from Pali jhna, from Sanskrit dhynam, from dhyti, he meditates
It is hard to believe that a word as Asian as Zen is ultimately an Indo-European word. Zen, which has been in English since 1727, is the Japanese pronunciation of Chinese chán, "quietude." Chán comes from Pali jhna, from Sanskrit dhynam, "meditation," from the Sanskrit root dhy-, dh-, "to see, observe." The Indo-European root behind the Sanskrit is *dhei-, *dhy-, "to see, look at." This root also shows up in Greek, where *dhy- developed into s-, as in Common Greek *sma, "sign, distinguishing mark." This became sma in Attic Greek, the source of English semantic.
