Hello, Heather421093! Both can be translated as " soup ". The main difference is that "supa" is clear and can be made with dumplings or noodles. Ciorba can be sour(you can use lemon, vinegar, bors) and made with egg yolk,sour cream or yogurt. Here you have an example of supa https://adygio.com/supa-de-pui-cu-taitei-de-casa/ and another of ciorba de burta https://adygio.com/ciorba-de-burta/
