Clear water or new water
Neosha is often cited as a variant of Neosho, a name of Native American origin (specifically Osage) meaning 'clear water' or 'new water'. It is also occasionally linked to the Greek prefix 'neo-', meaning new, though its usage in the US is most likely an American invention or a place-name derivative.
