In German, 'W-Fragen' are questions that start with a question word like 'wo', 'was', 'wer', etc. These are called 'W-questions' because most of the question words start with 'W'. The word order is different from normal sentences.
Use this structure in German when you want to ask for specific information, such as a place, time, person, or reason. These are not yes/no questions.
