Usage of Interrogative Adverbs

Interrogative adverbs are used in the following situations:

Conjugation of Interrogative Adverbs

Unlike verbs, interrogative adverbs are not conjugated because they are not action words. However, they are often used with helping verbs (is, are, does, did, can, will, etc.) in questions.

For example:

• How does this machine work? (with the verb does)
• Why did he leave early? (with the verb did)
• When will she arrive? (with the verb will)

1. Interrogative adverbs always introduce questions.
   • Where is my car?
2. They do not change form, regardless of tense.
   • Why did she cry? (past)

3. They are usually followed by a verb and subject.
   • How do you know him?
4. They can be used in indirect questions.
