The term 'บน (bon)' in Thai language is used to denote a position in regard to another object, which is understood to be 'below' or 'beneath'. It is equivalent to 'on' or 'above' in English. It is used to refer to something that is directly on or above another object. It can be used with most nouns, though context is important as there might be more appropriate words to use depending on the particular situation.
