An interrogative sentence is a type of sentence that is used to ask a question. It is characterized by a specific structure and punctuation, which sets it apart from other types of sentences.
The structure of an interrogative sentence typically involves an auxiliary verb or verb phrase followed by the subject of the sentence. For example, in the sentence "Do you want to go to the movies?", the auxiliary verb "do" is followed by the subject "you".
Interrogative sentences can also be identified by the use of question marks at the end of the sentence. These question marks serve to indicate that the sentence is a question and not a statement.
There are several types of interrogative sentences, including yes/no questions, wh-questions, and alternative questions.
Yes/no questions are questions that can be answered with a simple "yes" or "no". These types of questions often begin with an auxiliary verb, such as "do", "does", "is", or "are". For example, "Is it raining outside?" is a yes/no question.
Wh-questions are questions that begin with a wh-word, such as "what", "when", "where", "who", "why", or "how". These types of questions are used to gather specific information about a topic. For example, "What is your favorite color?" is a wh-question.
Alternative questions are questions that present two or more options and ask the reader or listener to choose between them. These types of questions often begin with the words "either" or "or". For example, "Do you want to go to the movies or stay at home?" is an alternative question.
In summary, an interrogative sentence is a type of sentence that is used to ask a question. It is characterized by a specific structure and punctuation, and there are several types of interrogative sentences, including yes/no questions, wh-questions, and alternative questions.
