What is the Thai word for "hello"?

The Thai word for "hello" is สวัสดี (sawasdee). This term is commonly used in various contexts and can be employed at any time of day, making it a versatile greeting in Thai culture. It is an essential part of daily interactions and reflects politeness, which is an important aspect of communication in Thailand.

The other options serve different purposes in the Thai language. ลาก่อน (la gon) means "goodbye," which is used to bid farewell rather than greet someone. ฉันรักคุณ (chan rak khun) translates to "I love you," expressing affection rather than a simple greeting. Meanwhile, น้ำ (nam) means "water," which is unrelated to greetings. Thus, สวัสดี (sawasdee) is clearly the correct choice for "hello."
