The Unreal Past

លក្ខខណ្ឌទី៣ (ការសន្មតផ្ទុយពីអតីតកាល)

The Third Conditional talks about an imaginary past. It is too late to change it now!

ការស្តាយក្រោយ និងការធូរស្បើយចិត្ត

If I had studied, I would have passed. Reality: I didn't study, so I failed. ប្រសិនបើខ្ញុំបានរៀន ខ្ញុំប្រហែលជាប្រឡងជាប់បាត់ទៅហើយ។

If we had left earlier, we wouldn't have missed the flight. Reality: We left late, so we missed it. ប្រសិនបើយើងបានចេញដំណើរឲ្យលឿនជាងនេះ យើងប្រហែលជាមិនខកជើងហោះហើរទេ។

You can put the result first. If "If" is in the middle, do NOT use a comma!

I would have passed if I had studied. ខ្ញុំប្រហែលជាប្រឡងជាប់បាត់ទៅហើយ ប្រសិនបើខ្ញុំបានរៀន។

gpp_maybe The "Would" Trap!

Never put "would" in the IF clause!

(កុំប្រើ "would have" នៅជាប់នឹងពាក្យ "If" ឲ្យសោះ! ត្រូវប្រើ "had + V3" ជានិច្ចនៅផ្នែកលក្ខខណ្ឌ។)

If I would have known... ❌

If I had known... ✅

Teacher, why do we sometimes say "If I had had time"? Is it a mistake to repeat "had"?

Hi Panha! It is NOT a mistake! It is perfectly correct. The first "had" is the helper verb for the Past Perfect tense. The second "had" is the V3 (Past Participle) of the verb "to have". So, "If I had had money..." means "If I owned money in the past...". Good catch! 💡

Can I use 'could have' or 'might have' instead of 'would have'?

Yes, absolutely! "Would have" means you definitely intended to do it. "Could have" means you had the *ability* to do it. "Might have" means there was a *possibility*. E.g., "If I had studied, I might have passed" (Maybe I pass, maybe not!). 🎓
