I realized the English word "woe" is related to the Assyrian word "wai" (as in the song, Wai Wai Minakh by Sargon Gabriel, meaning "woe from you"). Astonishingly, the proto-Indo European word is "wai", which is quite identical to the modern Assyrian word. Both "wai" and "akh" (which is also used in Arabic - "akh minak") are in the Syriac dictionary. And it appears that "wai" is a classical Syriac word. So maybe it has genetic ties to the proto-Indo European word *wai?
