Invalid word segmentation. This is an answered question. https://www.italki.com/question/427951 P.S. Do practice on getting the right segment of "Parts of Speech", learning Thai will be much easier. Edited and Updated: This time will be an example of doing a word segmentation. Segmenting of above sentence should be like this: แต่ว่า / อย่าไป / เสียเวลา / ของคุณ / ให้กับ / เรื่องเช่นนั้น / เลย Now you can google it to get a big picture at first stage. And you will get more accurate meaning. FYI.It would be better if you can pick up the right segment in asking a question, so the most Thais can help you more. But that is understandable in learning such a new thing, just keep doing practice.
