In English, 'have' expresses possession, relationships, and characteristics. 'Have' also forms perfect tenses as an auxiliary verb. In some contexts, 'have' can mean experience or undergo. These core meanings organize most common uses of 'to have'.

In the present simple, 'have' shows possession and stable facts. For third person singular, English uses 'has' instead of 'have'. This pattern applies to statements, questions, and negatives with do-support. Possessive 'have' often appears as 'have got' in some varieties.

I	have
you	have
we	have
they	have
he/she/it	has

'Have' forms the present perfect by combining 'have' or 'has' with a past participle. In this use, 'have' functions as an auxiliary, not as possession. The present perfect connects a past event to the present. The choice between 'have' and 'has' follows the same subject pattern as the present simple.

Subject	Form
I	have + past participle
you	have + past participle
we	have + past participle
they	have + past participle
he/she/it	has + past participle

In the past simple, 'had' is used for all subjects. 'Had' can express past possession, relationships, or characteristics. 'Had' also acts as an auxiliary in the past perfect. The form does not change with the subject.

Subject	Form
I	had
you	had
we	had
they	had
he/she/it	had

'Have' and 'had' build perfect tenses by linking to a past participle. The present perfect uses 'have' or 'has'; the past perfect uses 'had'. In these tenses, 'have' shows grammatical aspect, not ownership. The main meaning comes from the participle that follows.

Rule
The present perfect uses have or has plus a past participle to link past events to the present.
The past perfect uses had plus a past participle to show that one past event came before another past event.
In perfect tenses, have is an auxiliary and does not carry possession.

'Have got' is a common way to express possession in British English and some other varieties. It usually appears in the present tense with meanings like possession, relationships, or necessity. 'Have got' contracts to forms like 'I've got' and 'He's got' in speech and informal writing. In this construction, 'got' does not mean received; it forms a unit with 'have'.

Rule
Have got expresses possession or relationships in the present, especially in British English.
Have got typically contracts with pronouns in informal English.
Have got is not used as a perfect tense; it functions like present possessive.

In standard English, questions and negatives with possessive 'have' usually use do-support: 'Do you have' and 'I do not have'. With 'have got', questions and negatives use 'have' as an auxiliary: 'Have you got' and 'have not got'. With perfect tenses, 'have' is already an auxiliary and forms questions and negatives without do-support. The choice depends on whether 'have' is lexical or auxiliary in the sentence.

Rule
Possessive have forms questions and negatives with do-support: Do you have, I do not have.
Have got forms questions and negatives with have as an auxiliary: Have you got, have not got.
Perfect tenses form questions and negatives with have or had as an auxiliary: Have you seen, I have not seen.

'Have' combines with certain nouns to express experiences, actions, or states. These combinations often have fixed meanings, such as 'have breakfast' or 'have a look'.

Word/Phrase	Definition
have breakfast	I eat breakfast.
have a meeting	I participate in a meeting.

'Have' can express mental states or internal experiences. Common uses include 'have an idea', 'have a feeling', and 'have a thought'. In these cases, 'have' indicates holding or experiencing a cognitive event. The structure parallels possessive and experiential uses.
