OpenStreetMap and Way: Lacul Fortuna (28726206) | OpenStreetMap show a lake as “Lacul Fortuna” (“fortuna” being Romanian for “fortune”). I am pretty sure it should be “Lacul Furtuna” (“furtuna” being the definite-article form of Romanan “furtună”, meaning “tempest”). There are sites on line that use “Fortuna”, but I think they are mostly non-Romanian-language sites confusedly choosing a more common word with cognates in more languages. It is unlikely that so many Romanian-language sources would use the less common “Furtuna” if it was not correct.
(FWIW, I’m here because I am working on creating a Wikidata item for the lake.)
