To have sth done and to have sb do something

Imagine that you have a car that needs to be repaired. Imagine that you want someone (most likely, a mechanic) to repair it for you. How do we express that? Read on to learn!

Generally, we use "to have something done" to express the fact that an activity (for example, repairing a car) will be performed by an unknown subject.

• I must have my eyes tested.
• I had a picture of myself painted.

The subject can become a little "less unknown" if we add "by + noun" after the expression.

• I must have my eyes tested by a specialist.
• I had a picture of myself painted by an artist.
• I had my wallet stolen yesterday by a thief.

Note the past participle form of the verb.

Note the bare infinitive form of the verb.
