Lack of pronouns
BeginnerExplanation
Many times you will not see pronouns (i.e., I, you, he, she, etc) because when the context is clear, you can usually guess what the other person is talking about.
For example: ไม่ชอบ (mâi chôp) can mean "I don't like", "she doesn't like", "we don't like", etc - depending on the context.
Pattern
omit the pronoun when the context is clear
Examples
เป็นนักร้อง
bpen nák róng
He/she/I/you are a singer (depending on the context)
ชื่อเกรซ
chêu Grace
My/her/your name is Grace (if I am introducing myself, then of course it will mean "My name is Grace"
