Dicas e truques (4)

💡

Context is King

If you are unsure between 'dai' and 'pen', native speakers will still understand you. Don't stress too much!

💡

Placement

Always keep it before the action verb.

💡

Don't overthink

Keep it simple. Verb + dai mai is all you need.

💡

Drop the Subject

In casual Thai, you can often drop the subject (like 'I' or 'you') if it is clear who you are talking about.

Review Summary

  • Subject + Verb + ได้
  • Subject + ต้อง + Verb
  • Verb + ได้ + ไหม
  • Subject + อยาก + Verb

Erros comuns

Ability 'dai' must follow the verb, not precede it.

Wrong: ฉันได้ไป (I can go)
Correto: ฉันไปได้ (I can go)

'Tong' acts as a modal auxiliary and must come before the main verb.

Wrong: ฉันไปต้อง (I must go)
Correto: ฉันต้องไป (I must go)

You don't need 'dai' when using 'yak'; 'yak' already carries the desire to perform the action.

Wrong: ฉันอยากได้ไป (I want to go)
Correto: ฉันอยากไป (I want to go)
