Interrogative form

Key characteristics include:

• Inversion of subject and verb: Often, the auxiliary verb (e.g., do, be, have) comes before the subject.
  • Statement: You are happy.
  • Interrogative: Are you happy?
• Use of question words (wh-words): Words like who, what, where, when, why, how are placed at the beginning of the sentence.
  • Statement: She went somewhere.
  • Interrogative: Where did she go?
• Rising intonation: In spoken language, the pitch of the voice often rises at the end of a question.
• Question mark: In written language, an interrogative sentence always ends with a question mark (?).

Examples:

• Do you understand?
• What is your name?
• Have they finished the project?
• Why did the chicken cross the road?
