A question can stand alone or sit inside a sentence
A direct question asks something on its own: “Where is the library?” An indirect question puts that same uncertainty inside a larger sentence: “Do you know where the library is?” The meaning is similar, but the grammar changes. In the direct question, “is” comes before “the library.” In the indirect question, “the library” comes before “is.”
Indirect questions often follow phrases such as “Do you know,” “Can you tell me,” “I wonder,” and “She asked.” They can make a request sound less abrupt, but politeness is only one reason to use them. They also let us report a question or describe something we do not know: “She asked where the library was” and “I wonder where the library is.”
Use statement order inside the indirect question
Many direct questions place a helping verb before the subject. Compare “Where are the keys?” with “I can’t remember where the keys are.” The indirect part uses the order you would expect in a statement: subject, then verb. The same pattern works with other question words: “When will the film start?” becomes “Do you know when the film will start?”
Questions with “do,” “does,” or “did” need particular care. These words often help form a direct question, but they usually disappear from the indirect version. “What does this word mean?” becomes “Can you explain what this word means?” Notice that “means” now carries the present-tense ending. Likewise, “Where did Mara put the draft?” becomes “I wonder where Mara put the draft.”
Keep a helping verb when it belongs to the verb phrase, but move it after the subject. For example, “What have they changed?” becomes “Tell me what they have changed.” The reliable editing test is to find the question word, then read everything after it as though it were part of a statement.
Use if or whether for yes-or-no questions
A direct yes-or-no question has no question word to carry into the larger sentence. Instead, introduce the indirect question with “if” or “whether”: “Is the window open?” becomes “I wonder if the window is open.” “Have they finished?” becomes “Could you check whether they have finished?” The word order after “if” or “whether” is still subject, then verb.
In many everyday sentences, either word works: “I don’t know if it will fit” and “I don’t know whether it will fit.” “Whether” is especially useful when you name alternatives: “We need to decide whether to revise the opening or cut it.” Whichever word you choose, avoid carrying over direct-question order. Write “Do you know if the window is open?” rather than “Do you know if is the window open?”
Watch the exceptions and the punctuation
Not every direct question visibly changes. When the question word is the subject, there is no subject–verb inversion to undo. “Who called?” can become “I wonder who called.” “What happened?” can become “Tell me what happened.” These sentences follow the same underlying pattern; they simply look unchanged.
Punctuation depends on the whole sentence, not just the indirect question within it. “Could you tell me where the meeting is?” ends with a question mark because the speaker is asking something. “I know where the meeting is.” ends with a period because the whole sentence is a statement. And if you quote a direct question, keep its original wording: She asked, “Where is the meeting?” That is a quotation, not an indirect-question clause.
Try the change yourself
To turn a direct question into an indirect one, first choose a frame such as “I wonder” or “Do you know.” Next, keep the question word—or add “if” or “whether” for a yes-or-no question. Finally, put the subject before the verb inside the indirect question and check the punctuation of the complete sentence.
Try it with “Why did the editor move this paragraph?” One version is “I wonder why the editor moved this paragraph.” The “did” drops away, and “moved” shows the past tense. For “Can the ending be shorter?” you could write “Could you tell me whether the ending can be shorter?” The outer question has its own word order, while the clause after “whether” has statement order. Keeping those two layers separate makes indirect questions easier to write and edit.
