Hello! Let's learn to use the German word aus (meaning 'from') for countries of origin.
For most countries, simply use aus. For instance, Ich komme aus Deutschland (I come from Germany). No article (der, die, das) is needed.
However, some countries have an article. Use aus der Türkei (for die Türkei) or aus den USA (for die USA). Remember, most countries are article-free. You'll master it!
