It's easy. The verb in the infinitive is "to have". In the Present Simple, you use "have" for all persons, except for the 3rd singular, for which you use "has" (He has). In the Past Simple, it's always "had". For future and conditional forms, it's just like almost any other verb: for future, you add "will" or "shall", keeping the verb in the infinitive (He will have. He shall have.); for the conditional, you add "would" or "should" (He would have. He should have.).

About the auxiliary verb, it's also easy. For the Present Perfect, you use the verb "to have" in the Present Simple, followed by the main verb in the Past Participle (I have gone. He has gone.). Same thing for the Past Perfect, but with the verb "to have" in the Past Simple (I had gone. He had gone.).

The gerund is just "having".

I hope I've made myself clear. If you have any questions about this topic, just ask here.

mrmanshubhamWhat is the form of have (present participle, past participle, perfect, -ing form, singular noun form)?

I've never heard anything about "Present Participle". What is that?

"Singular noun form"?! "Have" is a verb, not a noun!!

About Past Participle, Present Perfect, Past Perfect, Gerund, and others, I've already mentioned them above. Have you not read my previous reply? It's everything in there, and in CalifJim's new reply, which I find to be more complete than mine, and has a lot of examples.

If you have any questions, ask, but don't ask things that we've already replied to!

And please, correct your misspellings. If I write "participle", you have to pay attention to that, and begin to write "participle" instead of anything else.

For all reasons above indicated, I feel like you didn't pay attention to my reply, and that makes me feel sad. If I notice that you don't pay attention to this or to any of my future replies, I will simply refuse to respond to any of your future questions.

sir, i read you previous reply. but actually sir whenever i solved sentence improvement, error detection and fill in the blanks, i always confused where to use past, present perfect and past perfect.
ex: i had had visit there, i have had lived there, i lived there.
sir, these type of question is always asked in the competition and almost i answer correctly but never answered confidentially. so please emphasized on present perfect, past, past perfect and infinitive with there imperative translation .

sir don't think i did not pay attention to your reply. i read it and little confusion are there so i asked you.

OK. In your second post to this thread, if you really wanted examples, you weren't clear about that. It looked like you wanted me to explain how the verb is formed all over again! You should have requested specifically examples, or it would look like you were asking what I had already answered.

I would be pleased to respond to you. Unfortunately, I don't have much time to give some examples here. I suggest that you read CalifJim's reply, and that you try to understand the examples he gives. If you have any question about one of the sentences specifically, ask for its meaning here, and we'll be pleased to answer. Also, if you don't understand some of the exercises you do, ask here any questions you have.

But if I were you, I would try to get an English teacher, preferentially who speaks your native language, so he/she can help you understand this. It should be more efficient than asking new questions about the usage of "have" each time you come here...

But don't misunderstand us: we'd still be pleased to answer any questions you have!

please explain use of has/have
