Cognate to Finnish allikko. Possibly from a Baltic language, compare Lithuanian šaltenis (“spring”) and šaltinis (“spring, source, that which is cold”). While the expected initial h- is seen in older Estonian texts, its loss in Finnish is unexplained, possibly due to similar words starting with ala-.
