Here are some examples:
* "Was ist das?" (What is that?)
* "Was möchtest du trinken?" (What would you like to drink?)
* "Was denkst du darüber?" (What do you think about that?)
"Quelle" can also be used in a broader sense to mean "source" or "origin". For example:
* "Die Quelle des Flusses" (The source of the river)
* "Die Quelle der Information" (The source of the information)
It's important to note that "quelle" is pronounced differently in German than "quelle" in French, where it means "spring" or "source."
