In Thai, how do you express "please"?

The expression "please" in Thai is conveyed through the word "กรุณา" (karuna). This word is a polite term often used when making a request or seeking permission, indicating respect towards the listener. Its usage is similar to how "please" functions in English, serving to soften requests and show consideration.

The other options represent different meanings: "ขอบคุณ" (khob khun) means "thank you," which expresses gratitude rather than a request; "ใช่" (chai) translates to "yes," indicating affirmation; and "ไม่" (mai) means "no," which negates a statement. Each of these words plays a distinct role in communication and does not serve the function of a polite request like "karuna" does.
