She has two daughters.
He has a bad temper.
He has no patience.
I have a bad cold.

Instead of have, we often use have got. Got forms of have are especially common in an informal style.

She has got two daughters.
He has got a German girlfriend. (More natural than ‘He has a German girlfriend.’)

In questions and negatives, have is almost always used with got or do. Note that in American English, short question and negative forms like have I? and I have not are not normally used.

Has she got a new car? OR Does she have a new car? (More natural than ‘Has she a new car?’)
I haven’t got an answer. (More natural than ‘I haven’t an answer.’)
She does not have manners. OR She hasn’t got manners. (More natural than ‘She hasn’t manners.’)

Note that got-forms of have are common in the present. They are not normally used in the past. We don’t, for example, say had got.

I had a strange experience last week. (NOT I had got a strange experience last week.)

He has got a new girlfriend. (More natural than ‘He has a new girlfriend.)
Has she got a car? OR Does she have a car? (More natural than ‘Has she a car?’)

Got-forms of have (and forms with do) are especially common in questions and negatives. In fact, in American English have is not normally used without got in questions and negatives.

Compare:

She hasn’t got a car. or She hasn’t a car. OR She doesn’t have a car. (British English)
She hasn’t got a car. OR She doesn’t have a car. (American English)
Have you got my keys? (More natural than ‘Have you my keys?’)

They do not have adequate facilities. OR They haven’t got adequate facilities. (More natural than ‘They have not adequate facilities’.)

Notes

Got forms of have are not normally used in short answers or question tags.

‘Have you got a new car?’ ‘No, I haven’t.’ (NOT No, I haven’t got.’)
She has got a new car, hasn’t she? (NOT …hasn’t she got?)

Got-forms of have are not very common in the past tense.

I had flu last night. (NOT I had got flu last night.)

Got is not generally used with the infinitive or -ing forms of have.

Got is not used with the do-forms of have.

Do they have a car? (NOT Do they have got a car?)

In British English have without got is possible in questions and negatives, although it is formal.

Have you a meeting today? OR Have you got a meeting today? OR Do you have a meeting today?

The anomalous finites do, does and did can be placed before the verb to show emphasis. Note that after do, does and did, we use a verb in its present tense form.

I do want you to come. (More emphatic than I want you to come.)
I did invite them. (More emphatic than I invited them.)
She did accept the invitation. (More emphatic than She accepted the invitation.)

Notes on the anomalous finites

Is, am, are, was, were

These verbs are usually anomalous and their negatives are formed by the simple addition of not or n’t.

She isn’t very intelligent.
You aren’t hard working.
They weren’t expected to come.
She wasn’t anxious about it.

Interrogatives are formed by the simple inversion of subject and verb without the use of do.

Isn’t she very intelligent?
Wasn’t she anxious about it?

Has, have and had

These are anomalous when used as auxiliaries to form the present perfect and past perfect tenses.

I have seen him. Have I seen him? I haven’t seen him.
I had told him. Had I told him? I hadn’t told him.
They have disappeared. Have they disappeared? They haven’t disappeared.

Has, have and had can be used as anomalous when used as a principal verb expressing the idea of possession.

She has a car. Has she a car? She hasn’t a car.
I have a watch. Have I a watch? No, I haven’t a watch.
She has long hair. Has she long hair? No, she hasn’t long hair.

Note that the questions ‘Has she a car?’, ‘Have I a watch?’, etc., are uncommon in American English. Instead, Americans use a structure with got.

I have got a watch. Have I got a watch? No, I haven’t got a watch.

Questions and negatives made with do/does/did are also common.

Do I have a watch? (More common than Have I a watch?)

No, I don’t have a watch. (More common than I haven’t a watch.)

Note that has, have and had aren’t anomalous when they express other ideas. In this case questions and negatives are formed with do and did.

I had (= experienced) an accident.
Did I have an accident? (NOT Had I an accident?)
I didn’t have an accident. (NOT I hadn’t an accident.)
I have (= take) a bath in the morning.
Do I have a bath in the morning?
I don’t have a bath in the morning.
