Plz can you send me about what different have and had .or when its used

past perfect. We use the verb had and the past participle for the past perfect: I had finished the work. The past perfect is used in the same way as the present perfect, but it refers to a time in the past, not the present.

Have and had are helping verbs Have: used in present thense that too in Perfect tense.... Have : i, you, we, they( for plurals).... Had: Used in past perfect tense Had: i, we, you, he, she, it, they.... ( for all singulars, plurals).. Have: present tense Had : past tense NOTE:::: has, had, have always followed by v3( third form of verb)..

Have is used with the first and second person singular present and plural tenses and the third person plural present tense. Again, in plain English, this just means you use have when you are speaking in the first and second person singular and third person plural, i.e., with the pronouns I, you, we, and they. I have a great deal for you.Do you have any money?We have a new ride at the amusement park.

Have and had helping verbs ex: I have completed dinner ex: I had completed dinner last night

have v1. had v2. had v3. having v4 we use present have we use past had
