Which of the following translates to "How are you?" in Thai?

The phrase that translates to "How are you?" in Thai is "สบายดีไหม" (sabai dee mai). This expression directly asks about someone’s well-being, mirroring the intent behind the English phrase. In Thai culture, inquiring about someone's health and happiness is a common way of showing care and interest.

The other options represent different meanings: "คุณชื่ออะไร" (khun chue arai) translates to "What is your name?" which is a completely different context focused on personal identification rather than well-being. "น้ำ" (nam) simply means "water," which is unrelated to greetings or inquiries about health. Lastly, "ขอบคุณ" (khob khun) means "thank you," a phrase used to express gratitude, rather than to inquire about one’s state of being. Understanding these distinctions is essential in effective communication in Thai.
