Lesson 10
Causatives and Fixed Verb Patterns: Have/Get, Let/Make, Help and Rather
This lesson groups five rules that students commonly confuse because they look similar on the surface. Look at the helper verb first; it determines the form that follows. Work through the examples slowly once; speed comes after the pattern is clear.
What you will learn
- Understand and apply: Do not confuse irregular past forms and past participles.
- Understand and apply: Causative 'have/get' can use object + past participle.
- Understand and apply: 'Let' and active causative 'make' take a bare infinitive.
- Understand and apply: 'Help' can take a bare infinitive or 'to'-infinitive.
- Understand and apply: 'Had better' and 'would rather' take the base form.
For every rule: spot the trigger → identify the grammatical relationship → apply the form → check meaning.
Before you start
Try the warm-up without checking the rule. The purpose is to expose the instinct you currently use, not to score marks.
Which sentence follows the target grammar pattern?
A. She had begun before I arrived.
B. She had began before I arrived.
Answer: A. Many irregular verbs have distinct simple-past and past-participle forms that must be selected according to the construction.
Rule 1 · G046
Do not confuse irregular past forms and past participles
Many irregular verbs have distinct simple-past and past-participle forms that must be selected according to the construction.
Correct example
She had begun before I arrived.
Incorrect example
She had began before I arrived.
Interpretation
Many irregular verbs have distinct simple-past and past-participle forms that must be selected according to the construction. In a test, do not memorise this as an isolated sentence. Look at the helper verb first; it determines the form that follows. The correct example shows the pattern in context; compare it directly with the incorrect version and identify the exact word that must change.
Why it matters
Auxiliaries sharply restrict the form that can follow, making these high-confidence marks once the pattern is recognised.
Common exam trap
Adding tense twice: once on the auxiliary and again on the main verb.
How to spot it
Mark the time words and order the events. Choose the tense only after the timeline is clear.
3-step solving method
- Circle the auxiliary or trigger.
- Write the form it requires (base/-ing/past participle).
- Check that tense is not marked twice.
Why the incorrect example fails
The target structure requires this rule: Many irregular verbs have distinct simple-past and past-participle forms that must be selected according to the construction. In the incorrect version, the repair is to replace “began” with “begun”. That is the exact edit a student should be able to justify in an error-spotting question.
Nuance and memory hook
Do not identify a form only by its spelling; the same -ed or -ing form can perform different grammatical jobs.
Many irregular verbs have distinct simple-past and past-participle forms that must be selected according to the construction.
Quick check
Without relying on what 'sounds right', explain which part of this sentence violates the rule: “She had began before I arrived.”

Rule 2 · G047
Causative 'have/get' can use object + past participle
Have/get + object + past participle means arranging for someone else to perform an action on the object.
Correct example
I had my laptop repaired yesterday.
Incorrect example
I had repaired my laptop yesterday by a technician.
Interpretation
Have/get + object + past participle means arranging for someone else to perform an action on the object. In a test, do not memorise this as an isolated sentence. Look at the helper verb first; it determines the form that follows. The correct example shows the pattern in context; compare it directly with the incorrect version and identify the exact word that must change.

- Check that tense is not marked twice.
Why the incorrect example fails
The target structure requires this rule: Have/get + object + past participle means arranging for someone else to perform an action on the object. In the incorrect version, the repair is to remove “repaired”; replace “yesterday by a technician.” with “repaired yesterday.”. That is the exact edit a student should be able to justify in an error-spotting question.

Rule 3 · G048
'Let' and active causative 'make' take a bare infinitive
After let and make + object in active constructions, use the base form without to.
Correct example
The mentor made us rewrite the paragraph.
Incorrect example
The mentor made us to rewrite the paragraph.
Interpretation
After let and make + object in active constructions, use the base form without to. In a test, do not memorise this as an isolated sentence. Look at the helper verb first; it determines the form that follows. The correct example shows the pattern in context; compare it directly with the incorrect version and identify the exact word that must change.
Why it matters

Common exam trap
Adding tense twice: once on the auxiliary and again on the main verb.
How to spot it
Look for the fixed trigger in the rule title before deciding whether the sentence merely sounds natural.

- Circle the auxiliary or trigger.
- Write the form it requires (base/-ing/past participle).
- Check that tense is not marked twice.

Rule 4 · G049
'Help' can take a bare infinitive or 'to'-infinitive
After help + object, both help someone do and help someone to do are standard.
Correct example
This method helps students identify the main idea.

This method helps students identifying the main idea.

Rule 5 · G050
'Had better' and 'would rather' take the base form
Use the bare infinitive after had better and would rather.
Correct example
You had better check the instructions again.

You had better to check the instructions again.
