wiktionary
Ultimately from Old East Slavic Москов-(Moskov-), originally referring to the Moskva River, probably from Proto-Slavic *mosky of unknown origin. Perhaps related to Czech moskva(“raw bread”), Slovak mozga(“puddle”), Polish Mozgawa, and more distantly Lithuanian mazgóti(“to wash, rinse”), Sanskrit मज्जति(májjati, “to sink”), Latin mergō(“to dive”). [1] The American placenames derive from the Russian city or from other sources; see the definitions below.
