4 experience: We had our roof blown off
Have + object + past participle can also be used in the sense of 'experience'. Again, the past participle has a passive meaning.
We had our roof blown off in the storm.
King Charles had his head cut off.
She's just had a short story published in a magazine.
S I won't have ...
I won't have + object + verb form can mean 'I won't allow .. .' I won't have you telling me what to do.
I won't have my house turned into a hotel.
239 have (6): have (got) to
1 meaning: obligation, certainty
We can use have (got) + infinitive to talk about obligation: things that it is necessary for us to do. The meaning is quite similar to must, for the differences, see 361.1.
Sorry, I've got to go now.
Do you often have to travel on business?
Have (got) + infinitive can also be used, like must, to express certainty. (This used to be mainly an American English structure, but it is now becoming common in British English.)
I don't believe you. You have (got) to be joking. Only five o'clock! It's got to be later than that!
2 grammar: with or without do; got
In this structure, have can be used like an ordinary verb (with do in questions and negatives), or like an auxiliary verb (without do). Got is usually added to present-tense auxiliary-verb forms.
When do you have to be back? When have you (got) to be back? Have got to is not normally used to talk about repeated obligation.
I usually have to be at work at eight. (NOT I've I:tSfttllly g6t ttJ •.•) Progressive forms are possible to talk about temporary continued obligation.
I'm having to work very hard at the moment.
For more details of the use of do-forms and got-forms of have, see 237.
3 future: have (got) to or will have to
To talk about the future, we can use have (got) to if an obligation exists now; we use will have to for a purely future obligation. Compare:
I've got to get up early tomorrow - we're going to Devon.
One day everybody will have to ask permission to buy a car.
Will have to can be used to tell people what to do. It .distances' the instructions, making them sound less direct than must (see 361).
You can borrow my car, but you'll have to bring it back before ten. For more about 'distancing', see 436.
