In the case of the Oka River in Russia, it is believed to have originated from the Finno-Ugric word "ukko" or "uhka", which means "big". This word was later adopted into the Russian language to refer to large rivers. Another theory suggests that "Oka" may have originated from the medieval Turkic word "yoku", meaning "left" or "north", as the river flows to the north of many inhabited lands in Russia.
For other rivers named Oka, their etymology will depend on the specific language and culture of the region where they are located.
