Questions are important in language learning in three main ways.
Firstly, and most obviously, the interrogative is a grammatical form which students need to learn to master. For users of a foreign language, the ability to ask questions is essential. It provides the key to moving around in a new environment, integrating into a community and finding essential information. Secondly, questions form one of the main tools which teachers use to check students comprehension and to get them to produce language. Many types of questions used in classrooms, however, are display questions that is, they require the students simply to show that they know something.
