Someone English native explain me this please.

typically, "I was" would be for something in the past, whereas "I were" would be for something that hasn't happened.
for example, "I was rich"
versus "I wish I were rich"

Hope this helps 😘

"I was" es la forma en pasado del verbo "to be" que se utiliza con el pronombre personal "I" en inglés. Se usa para describir acciones o estados pasados reales. Por ejemplo: "Ayer, yo estaba en casa."

"I were" no se usa comúnmente en inglés estándar como la forma en pasado de "to be" con el pronombre "I". En su lugar, "I were" se utiliza en el subjuntivo para expresar situaciones hipotéticas o irreales. Por ejemplo: "Si yo fuera rico, viajaría por el mundo."

En la conversación cotidiana y la escritura informal, "I was" es más común que "I were", ya que el subjuntivo se utiliza con menos frecuencia en el inglés moderno, especialmente en la lengua hablada. Por lo tanto, aunque "I were" puede ser gramaticalmente correcto en ciertos contextos, "I was" se utiliza más comúnmente en la comunicación diaria.

"I were" is used in the subjunctive.

I was there. (Indicative)
If I were there. (subjunctive)

When English speakers are studying another language, it is common for the instructor to introduce the subjunctive by saying, "English does not have a subjunctive."

But it does, in a half-baked way.

The simplest explanation is to use "I was" which is the singular form. The plural form would be "we were / they were. Hope that helps.

The most common difference is conditional:

"I was going to London by train",

but,

"If I were going to London I would go by train." (Or, "If I were to go..."

AI reflects only how it was programmed. It does not understand anything it says in any human terms.

If I were you, I would not be wearing what you are wearing. But I was too once like you.

I was to become a doctor. But I became an Engineer. If I were a doctor, then I would have become a gynecologist.

Bottom line - the subjunctive mood is firmly part of English, but people often fail to use it where it is appropriate. Newscasters, even presidents, miss using it. That's too bad, as they're just the people who keep our language proper--not snooty--[i]proper[/i], by using good examples. We Americans are lagging; it's too bad we don't have regular broadcasts of BBC to steady our rudder's wobble. Fail to use subjunctive mood where it applies, and set some of us cringing. Lose subjunctive and an important subtlety of expression is lost.

Once again:

If I [i]was [/i] there yesterday, I would need a witness to confirm it today (because I don't remember being there yesterday.)

If I [i]were[/i] there yesterday, I wouldn't need to show a parent's written absence excuse today.

I think they might have taught you wrong. "I were" pretty rarely used (in fact I'm struggling to think of a sentence that makes sense with it), though "you were" is quite common. Don't ask me why, it's one of those weird English rules everyone follows.

There are varying "rules" regarding was/were. Generally was is used for singular, I was, and were for plural, they were. A difference occurs when used with the word if. According to language.org ....
[quote]If I were is used when the subject of the sentence is referring to a hypothetical or imaginary situation.
○ If I were good at math and science, I would’ve become a doctor.
If I was is used to refer to a situation that actually happened in the past.
○ If I was late to school when I was younger, I’d get detention.[/quote]

So the only context we say "I were" is for example: "If I were to do x, then x would happen". It's uncommon but it's future tense and very specific.

"I was" is past tense and is the correct one in most contexts 🙂

Guys you are so nice. Now I understand!! Thank you all! 💙🤝

I were is past tense

I was or we were not correct to mix

The use of the word "was" versus "were" is wholly dependent on the subject being spoken in either 1st Person singular or 3rd Person plural.

For example, if you are only talking about yourself and therefore speaking in 1st Person singular terms, you would say "I was.."

However, if you are talking about someone else (3rd Person) and made reference to "they", then you would say "They were.."

To say "I were" is actually backward grammar because you'd be mixing 1st Person singular with 3rd Person plural. To say "I were" is like saying "They was", in terms of backward grammatical incorrectness.

The word "was" therefore is associated with " I " and the word "were" is associated with "they".
