Use

Each wh- question word is used to ask for different kinds of information.

Example:

When does he leave?

Explanation:

The word when asks what time or what day he leaves. We use the auxiliary verb does for wh- questions with he/she/it (third person singular).

How to build

The wh- question words with are what, when, where, why, whom, who, which, and how.

Wh- word + do/does + subject + the base form of the verb

• What do you eat?

When the wh- words who and what ask about the subject of the question, we don’t need the auxiliary verbs do/does.

• Who plays football?

Wh- word + simple present tense of the verb to be + subject

• Where are my keys?
