Question-phrase + か

Question-phrase + か is used to embed a question inside a larger sentence or to indicate an indirect question. It often appears when discussing or considering possibilities, causes, destinations, or timings without presenting the question as a direct, standalone inquiry. The tone can be neutral or cautious, especially when reporting what someone asked or wondered. When the main clause is a statement, the embedded question carries the same word order as a direct question, but it remains part of a larger sentence.
