Interrogative sentences are sentences that ask a question. They are typically characterized by:
* An interrogative word: These words signal a question, such as "who," "what," "where," "when," "why," "how," and "which."
* Inversion of subject-verb order: In most cases, the verb comes before the subject in an interrogative sentence. For example, "Are you going to the store?" instead of "You are going to the store."
* A question mark at the end: This punctuation mark is essential to identify a question.
Examples of interrogative sentences:
* What is your name?
* Where are you going?
* How old are you?
* Why are you laughing?
* Do you like pizza?
