This document discusses causative structures in English grammar. Causative structures indicate that one person or thing causes another to do something. They involve using verbs like "have", "make", "get", or "let" followed by a subject and the past participle form of another verb. Examples are provided like "I had John fix the car" and "The teacher made the students work in groups." Exercises are included asking the reader to complete sentences using causative structures, such as "Mrs. Brown had her house painted" and "I got Alice to lend me some money."
