Pronunciation Tip: Watch how native speakers connect the words in the result clause. "Would have" becomes "would've" (/wʊdəv/) and sometimes even sounds like "woulda" (/wʊdə/) in fast, informal speech. Try to mimic this rhythm!

Advanced Q&A
Brilliant observation, Vireak! You will absolutely hear native speakers say this in informal speech (especially in American English). However, it is considered **grammatically incorrect**. In formal speaking or exams like IELTS, you must strictly use "If I **had** known...". Good catch! 🕵️♂️
Can I use "might have" or "could have" instead of "would have" in the result clause?
Yes, you absolutely can! It just changes the meaning slightly.
• "Would have" = Certainty (I am 100% sure).
• "Might have" = Possibility (Maybe it would happen).
• "Could have" = Ability/Possibility (I had the ability to do it, but didn't). ✨
Teacher, "If I had had enough time" feels so strange to say. Is there a way to avoid saying "had had"?
It does feel strange at first! "Had had" is perfectly correct (Past Perfect of the verb 'have'). However, native speakers avoid the awkwardness by contracting the first 'had'. So instead of saying "If I had had", we write and say: "If I'd had enough time." It flows much better! 🗣️
Teacher, I often hear native speakers say "If I would have known..." on TV. Is this actually correct?
