Review Summary

  • Haam + [Verb]
  • Mai-dai + [Verb]

  • Mai + [Negative Adjective]

Common Mistakes

Mai-khoei is for 'never' (experience), not for specific past events.

Wrong: ฉันไม่เคยไปเมื่อวาน
Correct: ฉันไม่ได้ไปเมื่อวาน

Haam is too strong for personal advice; use Ya for friends.

Wrong: ห้ามคุณไป
Correct: อย่าไปเลย

Using a blunt negative instead of litotes can sound rude.

Wrong: งานนี้ไม่ดี
Correct: งานนี้ไม่เลว
