What is the Thai term for "please"?

The Thai term for "please" is "กรุณา" (karuna), which is used to make requests more polite. It functions as a way to soften the request or command, similar to how "please" is used in English. In Thai culture, politeness is highly valued, and therefore, using "กรุณา" when asking for something demonstrates respect towards the person being addressed.

The other terms provided serve different functions. "ขอบคุณ" (khob khun) means "thank you," which is used to express gratitude. "ใช่" (chai) translates to "yes," a simple affirmation. Lastly, "ไม่" (mai) means "no," used for negation. Each of these terms is important in Thai language and culture but does not serve the same purpose as "กรุณา" in polite requests.
