The English verbs let, make, have, get, and help are called causative verbs because they cause something else to happen.
Here are some specific examples of how causative verbs work in English sentences.
How to use causative verbs in English
LET = permit something to happen
- LET + PERSON/THING + VERB (base form)
- I don’t let my kids watch violent movies.
- Mary’s father won’t let her adopt a puppy because he’s allergic to dogs.
- Our boss doesn’t let us eat lunch at our desks; we have to eat in the cafeteria.
- Oops! I wasn’t paying attention while cooking, and I let the food burn.
- Don’t let the advertising expenses surpass $1000.
Remember: The past tense of let is also let; there is no change!
Note: The verbs allow and permit are more formal ways to say “let.” However, with allow and permit, we use to + verb:
- I don’t allow my kids to watch violent movies.
- Our boss doesn’t permit us to eat lunch at our desks.
MAKE = force or require someone to take an action
- MAKE + PERSON + VERB (base form)
- After Billy broke the neighbor’s window, his parents made him pay for it.
- My ex-boyfriend loved sci-fi and made me watch every episode of his favorite show.
- The teacher made all the students rewrite their papers, because the first drafts were not acceptable.
Note: When using the verbs force and require, we must use to + verb.
- The school requires the students to wear uniforms.
“Require” often implies that there is a rule.
- The hijacker forced the pilots to take the plane in a different direction.
“Force” often implies violence, threats, or extremely strong pressure
HAVE = give someone else the responsibility to do something
- HAVE + PERSON + VERB (base form)
- HAVE + THING + PAST PARTICIPLE OF VERB

GET = convince/encourage someone to do something
- GET + PERSON + TO + VERB

After “help,” you can use “to” or not – both ways are correct. In general, the form without “to” is more common:
- He helped me carry the boxes.
- He helped me to carry the boxes.
- Reading before bed helps me relax.
