Using 'were' when the subject is 'I' is called the Subjunctive Mood. There is a grammatical difference between using was or were in some structures with "were" signifying something that is an impossibility where as 'was' is something that is possible With "Wish" - in a wish structure you should only use 'were'; using 'was' is incorrect as you are wishing for something that you don't have. I wish I were smarter. (not) I wish I was smarter. With Conditionals - It is possible to use either "were" or "was" depending on how possible the condition is. If I were the president, I would... (this is extremely unlikely as I'm too lazy:) ) If I was wrong, I'm sorry (definitely possible as i make mistakes a lot) While this grammatical difference is well defined, fact is most native speakers (and indeed some teachers) don't know or care about the difference.

Hi Sara! We use I was. But in conditional sentences we use I were For example : If I were you, I would do it. Remember that we just use I were in these sentences! However sometimes native speakers say I was in conditional sentences but this is usually wrong. Hope this helps!😁

Salaam Sara, In English the custom is to use I was in all simple past situations. However, I were is the better option if we are using conditionals in the idea of giving advice to others. This is best illustrated in this phrase: If I were you, I would learn Spanish after finishing English. This is advice that is given to another person as a conditional; he advises the person to learn Spanish when he completes his English courses. In ALL other cases, use "I was."

hello I were is wrong
