English questions divide into yes-no questions and wh-questions. Yes-no questions ask for confirmation or choice and usually expect an answer like yes or no. Wh-questions ask for specific information and use words like who, what, where, when, why, and how. Each type has a typical word order that organizes the question clearly.

Word/Phrase	Definition
Yes-no question	A question that expects confirmation or denial.
Wh-question	A question that asks for specific information.
Choice question	A question that offers options to choose between.

In English questions with auxiliaries, the basic order is auxiliary plus subject plus main verb. This order is used in present simple and past simple with do and did, and in other tenses with be, have, or modal verbs. Placing the auxiliary before the subject marks the sentence as a question. Without this order, the sentence reads as a statement, not a question.

Rule
Place the auxiliary before the subject to form a question.
Use auxiliary + subject + verb for most questions.

Yes-no questions usually start with an auxiliary or a modal, followed by the subject and then the rest of the verb phrase. In present simple, use do or does; in past simple, use did. With be as a main verb, move be before the subject without do-support. With modals like can or will, place the modal before the subject.

Rule
Use do or does before the subject for present simple questions.
Use did before the subject for past simple questions.
Move be before the subject to question with be.
Place a modal before the subject to ask with modals.

Wh-questions begin with a wh-word, followed by the auxiliary, the subject, and the main verb. The wh-word identifies what information is requested. In questions where the wh-word is the subject, do not invert the subject and auxiliary because the wh-word already fills the subject slot. Most wh-questions in English rely on keeping the auxiliary before the subject, except when the wh-word is the subject itself.

Rule
Start with a wh-word to ask for information.
Use wh-word + auxiliary + subject + verb for most wh-questions.
Do not invert if the wh-word is the subject.

Short answers in English repeat the auxiliary or modal from the question to confirm or deny. The full verb phrase does not need to be repeated after yes or no. In questions with be, the short answer uses be; in questions with have, the short answer uses have. This pattern keeps answers clear and avoids unnecessary repetition.

Rule
Repeat the auxiliary or modal from the question in the short answer.
Use yes or no plus auxiliary for a complete short answer.

English typically uses rising intonation for yes-no questions in spoken language. Wh-questions usually use falling intonation because they expect information, not just confirmation. Intonation helps listeners identify that a sentence is a question, especially when word order is not enough. In writing, punctuation marks the question, but in speech, intonation carries much of the signal.

Rule
Use rising intonation for yes-no questions in speech.
Use falling intonation for wh-questions in speech.

English questions rely on auxiliary inversion for word order and on wh-words for information questions. Yes-no questions start with an auxiliary or modal, while wh-questions start with a wh-word and usually keep inversion. Short answers repeat the auxiliary, and intonation distinguishes question types in speech. Consistent word order and marking make questions clear to listeners and readers.
