Echo questions differ formally from interrogative sentences, yet they consistently have a questioning character. What is the source of this questioning character? Is the echo question an interrogative sentence, a unique sentence form, or a special kind of illocution? This study offers a survey of the features and analysis of echo questions, and classifies them as focus-generated questions with a pragmatically enhanced reproductive element.
