Indirect or embedded questions are questions that are asked in a polite, indirect way as part of a longer sentence. They are used in formal situations like writing and speaking to soften requests and make them more polite. Indirect questions have two clauses - an introductory clause that softens the request, and a second clause that asks the actual question. Some examples of indirect questions provided are "Do you know what time the staff meeting begins?" and "I was wondering why we need to do all the writing tasks." Indirect questions are a more polite way to ask questions compared to direct questions.
