What title is often used in Thailand to show respect?

In Thai culture, "Khun" is a term used as a respectful title similar to "Mr." or "Ms." in English. It is a versatile honorific that can be applied to both men and women when addressing someone formally or politely, and it is often used to show respect in various social interactions. Using "Khun" reflects an understanding of Thai social etiquette and conveys a level of formality and esteem toward the person being addressed.

While "Mr." and "Sir" are also titles of respect, they are limited to male individuals and do not encompass the inclusive nature of "Khun." "Madam," similarly, applies specifically to women. Therefore, "Khun" stands out as a culturally significant term that embodies Thai respect and politeness, making it the most appropriate choice in this context.
