The question word 'Was' (what) in German is used to find out the essence or characterization of something. It helps to ask questions about objects, actions, events or circumstances. "Was" is one of the most versatile question words and is often found in a variety of contexts.
Examples of using the question word "Was":
"Was machst du?" (What are you doing?) - In this question, "Was" is used to clarify the interlocutor's current action.
"Was ist das?" (What is it?) - This question can be asked when you want to know about an object or phenomenon that is unknown to you.
"Was hast du gestern gegessen?" (What did you eat yesterday?) - In this case, "Was" helps you learn about a food or drink consumed in the past.
It is important to note that "Was" can also change according to grammatical rules and context. For example, depending on the case and context, "Was" can be used in the forms "Wessen" (whose), "Wem" (to what, whom) and "Wen" (what, whom). This allows for more specific questions about objects, actions, or situations.
Thus, the question word "Was" plays an important role in forming questions about the essence and characteristics of objects or events in German, helping to clarify information and enrich communication.
