In Thai, 'บาง (baang)' is a common way to refer to an unspecified amount or a certain part of a whole, similar to the English term 'some'. It's often used to express a part of a whole, smaller groups within a larger group, some amount that is not the whole or the total, or a certain number or quantity that is not specified. Essentially, it's used when you don't want to or cannot give an exact number or amount. It is often placed before the noun it is describing.
