Causative 'have' and 'get' compared

Though have and get are often used interchangeably in the causative [> 12.11n1], get is more limited They are not interchangeable in e g / had a tooth out this afternoon

Get is stronger than have (and contains a stronger idea of action by the subject) in e g

/ must get this car serviced soon In eg

/ finally got my roof repaired there is a suggestion of difficulty, which would not be conveyed by had

Get sounds more natural than have in the imperative

Get your hair cut' Get your eyes tested¹

In suggestions with Why don t you? get is much stronger than have Why don t you have your hair cut? (neutral suggestion) Why don t you get your hair cut? (almost an order)

12.13.2 'Get' + to-infinitive to mean 'persuade', 'manage to', etc.

Get with an object before a to-infinitive conveys the idea of 'persuade'

or 'manage to'

/ finally got the car to start by asking everyone to push it

Sometimes we use get + object + past participle to say that we

managed to do something ourselves The stress is different from the

stress in causative sentences Compare / got the job done (stress on object = I did it myself) / got (or had) the \ob done, (stress on participle someone else did it)

In the first of these examples, got could not be replaced by had and

is not causative

12.13.3 Non-causative 'get' and 'have' + object + past participle

Get + object + past participle can be used in a non-causative way for accidents, disasters, etc that happen beyond our control

Non-causative have can be used in the same way [> 16.10] She had her house destroyed in an earthquake
