Have Something Done, Casuative Verb

These structures are used when someone employs another person to do an action. I will begin with the two main forms, some examples, and then look at some forms that are similar in structure but very different in meaning.

Structures

Someone + have + something + past participle (by someone)

Sam had his hair cut (by a hairdresser).

Someone + have + someone + verb + something

Sam had a hairdresser cut his hair.

Function and Points to Note

When we use these structures we are saying that Sam wanted a hair cut. He did not cut his hair but he employed/ asked another person to do the action.

It is also possible to replace have with get: Sam got his hair cut.

The verb have is changed to give the tense. e.g. Has for present simple, had for past simple etc

In the first structure above, it is most common to not use by someone.

We must be careful to use the correct verb form. Note that in the first structure the past participle is used and in the second the bare infinitive form of the verb is used. It is difficult to see this in my example because I have used an irregular verb. Please see the examples that follow.

Examples

The director has his appointments arranged by his secretary.
