Syntax
Wh- Questions always begin with one of the Wh- Question words (Interrogative pronouns), which show what kind of information is wanted.
It is very important to place an auxiliary or a modal verb after a Wh- Question and before a subject.
The Wh- Questions have this structure:
Wh- question word + auxiliary/modal verb + subject + verb + …?
- When does she read a magazine?
- Where did you live 10 years ago?
- Why have you got 5 cars?
- Which house is yours?
- What can I do now?
- Whose computer is this?
- Who ate all the chocolate?
- Whom did he call?
- How old are you?
The Wh- Words used to ask questions are:
- When (to ask for information about time);
- Where (to ask for information about place);
- Why (to ask for a reason);
- Which (to ask for information about a preference between two or more things);
- What (to ask for information about something);
- Whose (to ask for information about who something belongs to);
- Who (to ask for information about people, as a subject);
- Whom (to ask for information about people, as an object);
- How* (to ask for information about the way something is done, the way something happens).
These questions are also called Open Questions because the possible answers to them are infinite.
*How do not start with Wh-, but it is also considered to be a Wh- question.
NOTE: There are two main types of questions: Yes/No Questions and Wh- Questions. Yes/No Questions are Closed Questions because they can only be answered with Yes or No.
We tend to use Wh- Questions.
These are questions which always begin with one of the wh- question words, which show what kind of information is wanted:
- When (to ask about time);
- Where (to ask about place);
- Why (to ask for a reason);
- Which (to ask about a preference between two or more things);
- What (to ask about something);
- Whose (to ask about who something belongs to);
- Who (to ask about people, as a subject);
- Whom (to ask about people, as an object);
- How (to ask about the way something is done, the way something happens).
To form a wh-question, we have to follow this structure:
Wh- question word + auxiliary/modal verb + subject + verb + …?
For example:
— “Where is the toilet?” = The question word “where” suggests that the speaker needs to know the position of something.
NOTE: An auxiliary (be/have…) or a modal verb (can/could/would…) must be placed after a wh- question and before a subject.
