In Scandinavian languages, the letter Å means river.

The story behind the answer

True: in Swedish, Norwegian, and Danish, å is both a letter and a full word meaning “stream” or “small river.” You’ll see it in many place names and hydronyms—famously the village Å in Norway’s Lofoten. Scandinavian languages also distinguish river sizes: å for a small river, and älv (Swedish) or elv (Norwegian) for a large one.

Fun context: Danish spelling was reformed in 1948 to replace aa with å, which is why older forms like Aarhus and Aalborg coexist with Århus and Ålborg. Memory tip: the little ring over å looks like a drop of water sitting on a stream—å = waterway.
