This document provides guidance on forming WH-questions to ask about subjects, objects, complements, or other elements of a sentence. It explains that WH-questions are formed by omitting the element being asked about and using an appropriate question word or phrase followed by a helping verb and the main verb. Examples are provided of questions asking about subjects, objects, complements, time, place, manner and other details. Guidance is also given on selecting the correct helping verb based on the tense.
