44 questionsInstant feedback

A If I do… — a real, possible situation

If + present simple , will + base verb

Use this for things that may really happen in the future. The if-part uses the present simple; the main part often uses will / can / might (or an order):

likely futureIf it rains, we‘ll stay at home.

real adviceIf you study, you‘ll pass.

requestIf you see Tom, give him this.

💡 Never use will in the if-part: If it will rain… → If it rains…

B If I did… — an imaginary situation

If + past simple , would + base verb

Use this for situations that are imaginary, unlikely, or not true now. Here the past simple does not mean past time — it just means “imagine this”:

not true nowIf I had a car, I would drive. (I don’t have one)

a dreamIf I won the lottery, I would travel.

could / might tooIf we lived here, we could walk to work.

💡 No would in the if-part: If I would have time… → If I had time…

C Same sentence, different meaning

The tense after if changes the meaning. Present = it may happen; past = you’re only imagining:

*If I find* it…** real	I think I really might. → I’ll call you.
*If I found* it…** imaginary	I don’t expect to. → I would call you.

real If I see her, I will tell her. ✓

imaginary If I saw her, I would tell her. ✓

D If I were… — and giving advice

In imaginary sentences we often use were for every subject (I / he / she / it), not only was. This is very common in the advice phrase If I were you…:

advice If I were you, I’d say sorry. ✓

imaginary If he were here, he’d help. ✓

💡 If I were you… is the natural way to give advice — never If I am you.

📌

Remember — If + present simple … will + base = a real, possible future · If + past simple … would + base = imaginary or not true now · the past tense after if means “imagine”, not past time · use were (not was) for advice: If I were you…. Never if it will rain and never if I would have.
