"Were" is used for all pronouns in a hypothetical sense, in the present. We understand that the situation is imagined, or even impossible in the present.  When talking about reality, you only use "were" in the past, for plurals (this includes singular "you", which used to be only a plural form).

Look up "second conditional" and "subjunctive mood" if you want to learn more. There's plenty of information online.

But as I know before the verb to be is conjugated as "were" with the Pronoun "I" and was is strictly used for the third singular person: he, she, and it.

would you explain more. PLEASE.

"I were" is only used when giving advice in a hypothetical situation.

"If I were you, I would...."

You will hear people say, "If I was you, I would..." but strictly speaking they should use were, not was.

Hi Amer,

"I was" is the normal conjugation of the verb be. Occasionally we need to use the subjunctive mood in English:

I were, you were, he/she /it were, we were, you were, they were.

You use this mood typically in a 2nd conditional sentence:

"if I were you I'd see a psychiatrist"

Hope that helps :)
