Causative Have: Have Someone Do vs. Have Something Done
A generic causative-have owner is useful because it joins two related constructions that answer different surface questions. It does not replace the older narrow “have someone do vs. have someone to do” page, which continues to own the specific bare-infinitive error after a person object.
Causative have has two core patterns: have + person + base verb when you arrange for a person to act, and have + thing + past participle when you arrange for something to be done. The second pattern can also describe an unwanted event affecting someone, so meaning and context matter.
Key details
Choose the right form
| Question | Use | Why |
|---|---|---|
| Arranging for a person to act? | have + person + base verb | The person performs the following action. |
| Arranging for a thing to receive an action? | have + thing + past participle | The focus is the result/service, not the performer. |
| Describing an unwanted event affecting someone? | have + object + past participle can also fit | Context distinguishes adverse experience from an arranged service. |
Quick tests
Causative pattern test
Is the object a person who performs the next action?
If yes: Use have + person + base verb.
If no: If the object receives the action, consider have + object + past participle.
Caveat: Check the exact construction and meaning before applying the rule mechanically.
Examples
We had the electrician inspect the wiring.
A person object performs the action, so the following verb is the base form.
We had the wiring inspected before moving in.
The object receives the action, so the past participle pattern is used.
They had their car stolen overnight.
The same object + past participle pattern can describe an adverse experience.
Further guidance
Adverse Event
The have + object + past participle pattern can also describe something unwanted that happened to the subject: “They had their car stolen.”
Owner Boundary
The existing have-someone-do-vs-have-someone-to-do guide remains the narrow syntax owner for whether to follows the person object.
Person Pattern
Use have + person + base verb when you arrange for or cause that person to perform the action: “I had the technician check it.”
Thing Pattern
Use have + thing + past participle when the focus is on arranging for the thing to receive the action: “I had the laptop repaired.”
