CAUSATIVE

The causative is a common structure in English. It is used when one thing or person causes another thing or person to do something. This page will explain how causatives are formed, and how to use them.
Basic causative structures
There are two basic causative structures. One is like an active, and the other is like a passive. These examples use the causative verb "have":
I had John fix the car.
The active causative structure
Subject Causative verb Agent Action verb Object
Susan had her brother do her homework.
The police had the suspect stop his car.
We had the carpenter fix our window.
The passive causative structure
In the passive form, there is usually no agent. The action verb is in the past participle, and the object comes before it:
Subject Causative verb Object Action verb
We had our door fixed.
Yukiko had her hair cut.
Sanjay had the windows cleaned.
