In thai, to be has three different meanings. เป็น อยู่ and คือ
It is very easy in Thai because the words don't conjugate (ผัน) and so you only have to remember which situation you use them. However in English we must always remember how the verb changes based on the pronoun.
It can be confusing at first but they must be practiced.
Furthermore, the questions we ask will also change based on the person we are asking about, for example:
Do you see how the verb " to be" changes based on the pronoun?
