نکات و ترفندها (4)

💡

Word Order

Always put 'dai' after the verb. Think of it as 'Action + Possible'.
frontend.learn_grammar.from_rule: Ability 'Dai'
💡

Softening the tone

Add 'นะ' (na) after 'ต้อง' to make it sound less like an order.
frontend.learn_grammar.from_rule: Obligation 'Tong'
💡

Context is King

Since Thai doesn't have different words for 'can' and 'may', rely on the situation to understand the meaning.

💡

Subject dropping

You can drop the subject if it's 'I'.
