I am sure everyone knows how to say hello in Thai language…that’s right we say “สวัสดี“ [sà-wàt-dee]
“สวัสดี” [sà-wàt-dee] is also used to say goodbye as well, but it is used in formal situations such as when talking to your boss, or people you respect like teacher, parents etc.
Let’s learn how to say goodbye in more informal situations.
 I often use the word แล้วเจอกัน [léaw jer gan] to say goodbye to my friends which means see you later.
เจอ [jer] means to meet
กัน [gan] is the word that is put after the action that occurs between more than two people. It tells that you do that action to each other. เจอกัน [jer gan] = see each other
 เจอกันใหม่ [jer gan mài] means see you again later. Itsounds less intimate than แล้วเจอกัน [léaw jer gan]
ใหม่ [mài] in this phrase means again
 พบกันใหม่ [pób gan mài] has the same meaning as เจอกันใหม่ [jer gan mài] which means see you again later. The word พบ [pób] sounds very formal. I never use it at all, but some people do use it.
The phrase in no.2 and no.3 can also start with แล้ว [léaw] like in no.1, so you can say แล้วเจอกันใหม่ [ léaw jer gan mài] or แล้วพบกันใหม่ [léaw pób gan mài]
All the above are used to say goodbye, and you can end every phrase with นะ [ná] to make your statement milder and sound like a Thai. You can also add the polite particle ค่ะ [kâ] / ครับ [kráp] to add more politeness in your statement as well.
CHOKE-DEE KA 🙂
