How do you say Thank for your help in Thai?

There are several ways to say "Thank you for your help" in Thai, depending on the level of formality and the specific context. Here are a few options:

Formal:

* ขอบคุณสำหรับความช่วยเหลือของคุณ (Khop khun sa-rap khwam chuai-luee khong khun) - This is the most formal and polite way to express your gratitude. It literally translates to "Thank you for your help."

* ขอขอบคุณสำหรับความช่วยเหลือ (Khor khp khun sa-rap khwam chuai-luee) - This is another formal option, slightly less formal than the previous one. It translates to "I thank you for your help."

Informal:

* ขอบคุณนะ (Khop khun na) - This is a more casual and friendly way to say "Thank you" in general, and can be used for expressing gratitude for help.

* ขอบคุณสำหรับความช่วยเหลือ (Khop khun sa-rap khwam chuai-luee) - This is a less formal way of saying "Thank you for your help."

* ขอบคุณที่ช่วยนะ (Khop khun thi chuai na) - This means "Thank you for helping" and is a more informal way to express gratitude.

Adding a touch of politeness:

* You can add "ครับ" (krap) at the end of a sentence if you are male, or "ค่ะ" (kha) if you are female, to show politeness.

For example:

* ขอบคุณสำหรับความช่วยเหลือของคุณครับ (Khop khun sa-rap khwam chuai-luee khong khun krap) - "Thank you for your help." (Formal, male)

* ขอบคุณสำหรับความช่วยเหลือค่ะ (Khop khun sa-rap khwam chuai-luee kha) - "Thank you for your help." (Formal, female)

* ขอบคุณนะ (Khop khun na) - "Thank you." (Informal)

Remember to choose the appropriate phrase based on your relationship with the person you are thanking and the formality of the situation.
