* Intransitive verbs do not take a direct object. They express an action without directly acting upon something.
Example:
* The door opened. ("Opened" is intransitive; it doesn't take a direct object.)
To make "pushed" intransitive, you need to remove the object that it acts upon.
Here's an example:
* The door pushed open.
In this case, "pushed" is now intransitive because the sentence doesn't tell us *what* pushed the door open. It just describes the action of the door opening.
Other ways to make "pushed" intransitive:
* The crowd pushed forward. (The object is the direction, not a thing.)
* The car pushed through the snow. (The object is the obstacle, not a thing being pushed directly.)
