Suppose, as well as direct questions (such as Where are my keys?), there also exist indirect questions (also called interrogative content clauses), such as where my keys are. These are used as subordinate clauses in sentences such as "I wonder where my keys are" and "Ask him where my keys are." Indirect questions do not necessarily follow the same rules of grammar as direct questions. For example, in English and some other languages, indirect questions are formed without inversion of subject and verb (compare the word order in "where are they?" and "(I wonder) where they are"). Indirect questions may also be subject to the changes of tense and other changes that apply generally to indirect speech.
Questions that ask whether or not some statement is true are called yes–no questions (or polar questions, or general questions), since they can in principle be answered by a “yes” or “no” (or similar words or expressions in other languages). Examples include “Do you take sugar?”, “Should they be believed?” and “Am I the loneliest person in the world?” A type of question that is similar in form to a yes–no question, but is not intended to be answered with a “yes” or “no”, is the alternative question (or choice question). This presents two or more alternative answers, as in “Do you want fish or lamb?”, or “Are you supporting England, Ireland or Wales?” The expected response is one of the alternatives, or some other indication such as “both” or “neither” (questionnaire forms sometimes contain an option “none of the above” or similar for such questions). Because of their similarity in form to yes–no questions, they may sometimes be answered “yes” or “no”, possibly humorously or as a result of misunderstanding.
