The term 'มั้ย (mái)' is used in Thai language to convert a statement into a question, similar to the English 'isn't it?', 'right?', or 'don't you?'. It is typically placed at the end of sentences. It is versatile and can be used with a wide range of sentences, transforming them into questions. This question particle does not alone indicate tone of surprise or disbelief like the English usage of 'right?' or 'isn't it?', hence context or added emphasis in speech could be used for that purpose.
