Past Simple: Negatives

How do we talk about things that DID NOT happen in the past?

តើយើងនិយាយអំពីអ្វីដែល "មិនបានកើតឡើង" ក្នុងអតីតកាលដោយរបៀបណា? ប្រើ didn't + កិរិយាសព្ទដើម!

star The "To Be" Exception

ករណីលើកលែងចំពោះ Verb To Be

We DO NOT use "didn't" with Was or Were!

Just add "not" to make: wasn't / weren't.

I wasn't happy. ខ្ញុំមិនសប្បាយចិត្តទេ។ (NOT: I didn't be happy)

They weren't at home. ពួកគេមិននៅផ្ទះទេ។ (NOT: They didn't be at home)

warning The Double Past Trap!

Only use ONE past tense marker!

(ពាក្យ "didn't" បានប្រាប់រួចហើយថាវាជាអតីតកាល ដូច្នេះកុំប្តូរកិរិយាសព្ទទៅជាអតីតកាលម្តងទៀត!)

Yes, absolutely! "Didn't" is just the short, spoken form of "did not". We use "didn't" mostly in talking and casual writing, but in formal essays, you should write "did not". ✍️

Why can't I say "I didn't was at home"? "Was" is the past tense of "be".

That's a very common mistake! The verb "to be" (was/were) is special. It doesn't need "did" to help it make a negative or a question. It is strong enough on its own! So we just add "not": "I was not (wasn't) at home." 🏠
