نهره

• Ultimately of Semitic origin; if not from Arabic نَهْر (nahr, “river”) by a multistep semantic change as in river → liquid → milk → churn, from Aramaic נַהְרָא / ܢܰܗܪܴܐ (nahrā, “river”) in the sense of canal pertinent to urbanized Mesopotamia used figuratively for the passageway of milk.
• Possibly from the Iranian root Proto-Indo-Iranian *nayH- (“to churn butter”), from Proto-Indo-European *neyH- (“to make butter, churn”). Cognate with Sanskrit (नव-)नीत ((nava-)nīta, “fresh butter”); outside of Indo-Iranian, cognate with Latvian nīt (“used in sviestu nīt (to make butter)”) and paniņas (“buttermilk”).
