[Grammar] Causative

[Proficiencystudent]

Can somebody explain to me "when should I use V1 and when should I use V3" while using causative?
For example,
She had him (open/opened) a design house. Why is this "open"?
In addition, I saw some examples of 'have+something+done(V3)'. What is the difference?

Thank you.

Can somebody explain to me (no quotation marks here) when [STRIKE]should[/STRIKE] I should use V1 and when [STRIKE]should[/STRIKE] I should use V3 (no quotation marks here) while using the causative?

For example:

"She had him (open/opened) a design house." Why [STRIKE]is[/STRIKE] does this sentence use "open"?

In addition, I saw some examples of 'have+something+done space before opening bracket (V3)'. What is the difference? The difference between this and what?

Thank you.

Welcome to the forum. :hi:

Please see my corrections above.

In your first, the bare infinitive follows "to have someone do something".

I had him wash my dog.
He had his mother clean his room.
They had their friend steal a car for them.

I don't really understand your second question. Can you give us an example sentence including "have + something + done + V3"?

Examples:

"I had my room cleaned."
"I had my office repainted."
"I had my wallet stolen."

I was asking the difference between 'have + something + V3 ' and 'have + something + V1 '
