What does Sawadika mean?
“Sawadika” is how the Thai greeting สวัสดีค่ะ (sà-wàt-dee kâ) is usually written in English. It is the everyday Thai hello, said by a woman. A man says สวัสดีครับ (sà-wàt-dee kráp).
One word covers both hello and goodbye, at any hour. Thai does not swap greetings for morning, afternoon and evening the way many languages do.
Kâ and kráp mean nothing on their own. They are politeness particles that soften a sentence, and Thai speakers add them to almost everything when talking to someone they have just met.
