What is a common greeting used in Thailand?

Sawasdee is a traditional greeting in Thailand and is widely recognized as a way to say "hello." It is often accompanied by a gesture known as the "wai," where the palms are pressed together in a prayer-like fashion, and a slight bow of the head is made. This greeting conveys respect and is an important aspect of Thai culture, reflecting social hierarchy and politeness in interpersonal interactions.

In contrast, the other options represent greetings from different cultures or languages. Yasou is a greeting in Greek, Salam is commonly used in Arabic-speaking countries, and Bonjour is a French way of greeting someone. Although these terms are appropriate in their respective languages, they do not apply to Thai social customs. Understanding the use and cultural significance of greetings like sawasdee is essential for effective communication and rapport building in Thailand.
