Another in my occasional series featuring dubious statements about language by scholars in other fields: Nelson Goering posts on FB about a book on Vietnamese history he’s reading in which the author claims the Vietnamese word for water, nác/nước, derives from “one of the archaic Vietnamese terms for woman (nàng).” (This is in service of a point about “a possible Earth Mother cult,” which makes me sigh an entirely separate sigh.) Now, I know next to nothing about Vietnamese etymology, but I know enough to be skeptical about that, and sure enough, a quick visit to Wiktionary informed me that nước is “From Proto-Vietic *ɗaːk (‘water’), from Proto-Mon-Khmer *ɗaak (‘water’).” (If you’re curious about that archaic Vietnamese term for woman, nàng, it’s from Proto-Tai *naːŋᴬ ‘lady.’) I realize the Vietnamese word starts with n- and the protoforms with d-; I am assuming this is a regular or at least explicable development or it wouldn’t be stated with such assurance, but as I say, I am ignorant about Vietnamese etymology, so if there is reason to think Wiktionary is wrong (which, of course, it not infrequently is) and the historian is right, by all means let me know.
