"Could" គឺជាទម្រង់អតីតកាលរបស់ "Can"។ យើងប្រើវាដើម្បីនិយាយអំពីអ្វីមួយដែលយើង "អាច" ធ្វើបានកាលពីមុន។

No, Vireak! "Could" is a special word called a modal verb. It doesn't need help from "did". It makes its own negative: "couldn't" (could not). So, "I couldn't swim" is correct! ✨

Excellent question, Bopha!
"I didn't run" means you *chose* not to run (maybe you walked instead).
"I couldn't run" means you *had no ability* to run (maybe your leg hurt, or you were too tired). It was impossible! 🏃♀️❌
Teacher, can we say "did could"? Like "I didn't could swim"?
