Etymology
The river's name evokes slow or muddy waters considering the words it is related to: Lithuanian/Latvian sulà "birch sap", Old Prussian sulo "curdled milk", Norwegian dialectal saula "dirt", Sanskrit súrā "spiritous liquor", and Avestan hurā "intoxicating drink, kumis". Another etymology of the hydronym Sula is the Turkic suly, 'filled with water, wet'.
