There are 3 Verb to be - pben, yuu and khuu เป็น อยู่ คือ
Hi There! I would like to show you about interesting Thai language and culture.
The general forms pêe and nóng are used as personal pronouns and are also used as titles before someone's name, though the way they are used is somewhat different.
Thais speaking English may translate pêe and nóng as "brother" or "sister" regardless of the actual relationship, so be aware that someone introduced as a "brother" for instance may in reality not be a genuine brother, but perhaps a cousin, a friend or even boyfriend or husband.
