Causative verbs are an essential aspect of English grammar that often confuses learners. They allow the speaker or writer to indicate that someone causes another person to do something or that something causes a particular action. Mastering causative verbs can significantly enhance your ability to express more complex ideas and relationships between actions. This comprehensive guide will delve into what causative verbs are, how to form them, and provide practical examples and exercises to solidify your understanding.
What Are Causative Verbs?
Causative verbs are verbs used to indicate that one person causes another person to do something, or that something causes a particular action. In English, the most common causative verbs are make, have, let, get, and help. Each of these verbs has its own specific structure and usage rules.
Make
The verb “make” is used to indicate that someone is forced or compelled to do something. The structure is:
Subject + make + person + base form of the verb
For example:
– She made her brother clean the room.
– The teacher made the students rewrite their essays.
In these sentences, the subject (She/The teacher) causes another person (her brother/the students) to perform an action (clean the room/rewrite their essays).
Have
The verb “have” is used to indicate that someone arranges for another person to do something. The structure is:
Subject + have + person + base form of the verb
For example:
– I had the mechanic fix my car.
– She had her assistant schedule the meeting.
Here, the subject (I/She) arranges for another person (the mechanic/her assistant) to perform an action (fix my car/schedule the meeting).
Let
The verb “let” is used to indicate that someone allows another person to do something. The structure is:
Subject + let + person + base form of the verb
For example:
– Her parents let her go to the party.
– He let his friend borrow his car.
In these examples, the subject (Her parents/He) allows another person (her/his friend) to perform an action (go to the party/borrow his car).
Get
The verb “get” is used to indicate that someone persuades another person to do something. The structure is:
Subject + get + person + to + base form of the verb
For example:
– I got my friend to help me with the project.
– She got her brother to take out the trash.
In these sentences, the subject (I/She) persuades another person (my friend/her brother) to perform an action (help me with the project/take out the trash).
Help
The verb “help” is used to indicate that someone assists another person in doing something. The structure can be:
Subject + help + person + base form of the verb
or
Subject + help + person + to + base form of the verb
For example:
– He helped his sister move to a new apartment.
– She helped her friend to finish the assignment.
Both structures are correct, and the choice between them often depends on personal preference or regional usage.
Forming Causative Verbs in Different Tenses
Just like other verbs, causative verbs can be used in different tenses to indicate actions occurring in the past, present, or future. Here’s how you can form causative verbs in various tenses:
Present Tense

Past Tense

Using Causative Verbs with Passive Voice
Sometimes, the focus is on the action or the person affected by the action rather than the person causing the action. In such cases, you can use the passive voice with causative verbs.
Make
Active: The teacher made the students rewrite their essays.
Passive: The students were made to rewrite their essays by the teacher.
Have
Active: I had the mechanic fix my car.
Passive: I had my car fixed by the mechanic.
Let
“Let” is rarely used in the passive voice because it is generally used to express permission. However, if necessary, you can rephrase the sentence to focus on the action:
Active: Her parents let her go to the party.
Passive: She was allowed to go to the party by her parents.
Get
Active: She got her brother to take out the trash.
Passive: She got the trash taken out by her brother.
Help
Active: He helped his sister move to a new apartment.
Passive: His sister was helped to move to a new apartment by him.
