Why Causative Errors Persist at C1
Even advanced learners confuse causative structures because English employs multiple verbs (make, have, get, let) with subtly different meanings and complementation patterns. The distinction between bare infinitives and gerunds, combined with the semantic nuances each verb carries, creates a fertile ground for errors. Native intuition often fails when learners try to transfer patterns from their L1 or over-generalize one structure across all causatives.
Correct vs. Incorrect Causative Structures at a Glance
| Category | Incorrect Usage | Correct Usage | Explanation |
|---|---|---|---|
| MAKE — force or cause someone to do something | |||
| Form | make + object + to + base verb | make + object + bare infinitive (no "to") | "Make" is a bare infinitive causative; adding "to" is the most common learner error. |
| When to use | — | When someone is forced or compelled to do something, often without a choice. | Implies authority, pressure, or an irresistible cause. |
| Positive example | She made him to apologise. | She made him apologise. | Drop "to" after "make" in the active voice. |
| Negative example | They didn't make the students to stay late. | They didn't make the students stay late. | The rule applies in negative sentences too — no "to". |
| Question example | Did they make you to sign the contract? | Did they make you sign the contract? | Same structure in questions — bare infinitive always. |
| Key signal words | — | force, compel, require, oblige, pressure | These signals suggest "make" is the right causative to use. |
| HAVE — arrange for someone to do something for you | |||
| Form | have + object + to + base verb | have + object + bare infinitive (person does it) OR have + object + past participle (thing receives the action) |
Do not add "to". Use bare infinitive when the object is a person; use past participle when the object is a thing being acted upon. |
| When to use | — | When you delegate a task to someone else, often a professional or subordinate. No coercion implied. | Neutral in tone — simply arranging for something to be done. |
| Positive example | I had the mechanic to fix my car. I had my car fix. |
I had the mechanic fix my car. (person + bare inf.) I had my car fixed. (thing + past participle) |
No "to" with a person. When the object is a thing receiving the action, use the past participle form. |
| Negative example | She didn't have her nails do. | She didn't have her nails done. | When the object (nails) receives the action, use the past participle, not the base form. |
| Question example | Did you have the plumber to check the pipes? | Did you have the plumber check the pipes? | Remove "to" — the plumber is the agent performing the action, so use bare infinitive. |
| Key signal words | — | arrange, delegate, hire, pay someone to, commission | Suggests a service or delegated task — "have" fits best. |
| GET — persuade or arrange for someone to do something | |||
| Form | get + object + bare infinitive (no "to") | get + object + to + base verb (person) OR get + object + past participle (thing) |
"Get" is unique: it REQUIRES "to" before the verb when the object is a person. With things, use the past participle. |
| When to use | — | When persuading or convincing someone to do something, or when informally arranging for something to be done. | More informal and conversational than "have"; implies some effort to persuade. |
| Positive example | I got my brother help me move. I got my phone repairing. |
I got my brother to help me move. I got my phone repaired. |
Always use "to" with a person; use the past participle (not -ing) when the thing receives the action. |
| Negative example | I couldn't get him understand the problem. | I couldn't get him to understand the problem. | "To" is mandatory with "get" when the object is a person. |
| Question example | How did you get her agree to that? | How did you get her to agree to that? | "To" remains in questions — never drop it with "get". |
| Key signal words | — | convince, persuade, encourage, talk into, manage to arrange | Suggests effort or persuasion — "get" is the natural choice. |
| LET — allow someone to do something | |||
| Form | let + object + to + base verb | let + object + bare infinitive (no "to") | Like "make", "let" takes a bare infinitive. Adding "to" is incorrect. |
| When to use | — | When giving permission for someone to do something; the subject has the authority to allow or deny. | Implies willingness or permission from the subject — no force involved. |
| Positive example | She let him to borrow her car. | She let him borrow her car. | Remove "to" — "let" always uses the bare infinitive. |
| Negative example | My parents didn't let me to go to the party. | My parents didn't let me go to the party. | Negation doesn't change the structure — still no "to". |
| Question example | Will you let me to try it? | Will you let me try it? | Bare infinitive in all sentence types with "let". |
| Key signal words | — | allow, permit, give permission, not stop, enable | When permission is the core meaning, "let" is appropriate. |
| BONUS: Common Confusion — "Allow" vs "Let" | |||
| Form confusion | They allowed him go early. They let him to go early. |
They allowed him to go early. They let him go early. |
"Allow" uses "to + infinitive"; "let" uses the bare infinitive. Learners often mix up which needs "to". |
| Passive voice note | He was let leave early. (passive of "let") | He was allowed to leave early. (use "allow" in passive) | "Let" has no standard passive form. Switch to "allow" + to-infinitive in the passive voice. |
Key Difference Summary — Causative Verbs at a Glance
MAKE = force → bare infinitive (no "to")
HAVE = arrange → bare infinitive (person) / past participle (thing) — no "to"
GET = persuade → always needs "to" (person) / past participle (thing)
LET = permit → bare infinitive (no "to")
The single most important rule: Only GET uses "to" + infinitive with a person. MAKE, HAVE, and LET all use the bare infinitive. Additionally, when the object is a thing receiving the action (not the agent doing it), both HAVE and GET use the past participle, never the base verb or -ing form.

When to use it
Delegating work or services
Use 'have' when you arrange for someone to do something for you. Use 'have' + past participle for completed services.
"I had the plumber install a new sink yesterday."
Forcing or compelling someone
Make causative expresses unavoidable force or causation. The object cannot refuse; the action results directly.
"The unexpected news made her reconsider her entire strategy."
Persuading or encouraging
Get implies effort, negotiation, or persuasion. Always requires 'to' before the infinitive to show the target of influence.
"We managed to get the stakeholders to invest in the new project."
Allowing or permitting
Let grants permission or freedom. The object has agency or choice, unlike with make.
"The organisation lets remote workers choose their own schedules."

Common Mistakes
✕
Wrong
The manager made him to rewrite the report.
✓

The manager made him rewrite the report.
Make + object + infinitive never takes 'to'. The bare infinitive is mandatory with 'make'.
✕
Wrong
I got the mechanic fixing my car yesterday.
✓
Correct
I got the mechanic to fix my car yesterday.
Get causative requires 'to' before the infinitive. The gerund form is grammatically incorrect here.
✕
Wrong
She had her assistant to prepare the presentation.

She had her assistant prepare the presentation.
Have causative uses a bare infinitive, not 'to'. This applies to both past and present contexts.
✕
Wrong
The teacher let the students to leave early.
✓
Correct
The teacher let the students leave early.
Let always requires a bare infinitive. Adding 'to' violates the fundamental structure of this causative.
✕
Wrong
We made repaired the broken equipment.
✓
Correct
We had the broken equipment repaired.
You cannot 'make' someone repair something using a past participle. Use 'have' + object + past participle for passive causation.
✕
Wrong
He got his essay written by a tutor, but he didn't get understanding the feedback.
✓
Correct
He got his essay written by a tutor, but he didn't get to understand the feedback.
Get + to + infinitive (permission/opportunity) differs from get + object + past participle (completion). Don't confuse the two patterns.
✕
Wrong
I'll make you to see my point of view eventually.
✓
Correct
I'll get you to see my point of view eventually.
Make (without object manipulation) cannot causally link to complex actions. Use 'get' for persuasion or encouragement.
KEY TAKEAWAYS
What to Remember
- Use MAKE with bare infinitives for direct causation; GET requires to-infinitive and implies more effort or difficulty.
- HAVE typically means delegating a task to someone else; it pairs with bare infinitives in active voice.
- LET indicates permission or allowance and always takes a bare infinitive, never a to-infinitive or gerund.
- Each causative verb carries distinct semantic nuances; choosing wrong verb changes meaning even when grammatically similar structures exist.
- Avoid transferring L1 causative patterns; English causatives don't always match your native language's structure or complementation rules.
