Common Mistakes

You cannot use 'Phuea' (purpose) for feelings/states. Use 'Phro' (reason) instead.

Wrong: ฉันกินเพื่อหิว (I eat to hungry)
Correct: ฉันกินเพราะฉันหิว (I eat because I am hungry)

Dang-nan needs a preceding cause to make logical sense.

Wrong: ดังนั้นฉันไปบ้าน (Therefore I go home)
Correct: ฝนตก ดังนั้นฉันจึงกลับบ้าน (It rains, therefore I go home)

Phuea must follow the action, not start the sentence.

Wrong: เพื่อฉันไปเที่ยว (For I go travel)
Correct: ฉันไปเที่ยวเพื่อพักผ่อน (I travel to relax)

Next Steps

You've conquered the 'why' and 'how'! Keep connecting those ideas and you'll be fluent before you know it.
