gpp_maybe The Stative Verb Trap!

No -ING for feelings or facts!

(កិរិយាសព្ទបញ្ជាក់ពីស្ថានភាព (Stative Verbs) ដូចជា know, love, believe មិនអាចប្រើក្នុងទម្រង់ Continuous (កំពុងបន្ត) បានទេ!)

I have been knowing him for years. close

Incorrect. "Know" is a state, not an action.

I have known him for years. check

Correct. Use Present Perfect Simple instead!

Teacher, do native speakers really use all 12 tenses in daily conversation?

Hi Serey! Great question. Honestly, no! Native speakers use the Simple tenses (Present, Past, Future) and the Present Perfect about 80% of the time. The complex ones like "Future Perfect Continuous" are quite rare. But as a B2 student, you need to understand them all so you can read advanced texts and express very specific timelines! ⏳

I always get confused between Past Perfect and Past Simple. Which is harder?

Sopheak Pich Teacher 3 hours ago

They can be tricky! The best trick is to draw a timeline. Past Simple is just one point in the past. Past Perfect is the "Past of the Past"—it MUST happen *before* another past action. If you only have one action, just stick to Past Simple! ✍️
