How to Form Interrogative Sentences in English

In English grammar, interrogative sentences are sentences that ask a question. They can be formed by inverting the subject and the auxiliary verb in the sentence. The auxiliary verb is usually the verb "to be," "to do," or "to have." For example, in the sentence "He is going to the store," the corresponding interrogative sentence would be "Is he going to the store?"

When forming interrogative sentences in the present simple tense, we use the auxiliary verb "do" or "does." For example, "He plays basketball" becomes "Does he play basketball?" In the past simple tense, we use the auxiliary verb "did." For example, "She sang a song" becomes "Did she sing a song?"

For interrogative sentences with the verb "to be," we invert the subject and the verb "to be." For example, "She is happy" becomes "Is she happy?"

It's important to note that when forming questions in English, we use a rising intonation at the end of the sentence to indicate that it is a question. Interrogative sentences are an essential part of English communication, as they allow us to gather information, seek clarification, and engage in conversations.
