GET / HAVE SOMETHING DONE (Passive Voice)
This construction is passive in meaning. It may describe situations where we want someone else to do something for us.
Examples
- I must get / have my hair cut.
- When are you going to get that window mended?
- We're having the house painted.
If the verb refers to something negative or unwanted, it has the same meaning as a passive sentence:
- Jim had his car stolen last night. (= Jim's car was stolen)
- They had their roof blown off in the storm. (= Their roof was blown off in the storm)
The construction can refer to the completion of an activity, especially if a time expression is used:
- We'll get the work done as soon as possible.
- I'll get those letters typed before lunchtime.
In all these sentences, we are more interested in the result of the activity than in the person or object that performs the activity.
