It's the term you see up here. It should be also on that sheet, Tanakh, which is really the letter "t", "n" and "kh", and they've put little "a's" in there to make it easy to pronounce, because kh is hard to pronounce, so Tanach. Okay?

就是这个，这个词应该也在这张单子上，塔纳赫-Tanakh，这字母分别发t，n和kh？,他们在这里加了个a’s，让它变得容易发音？,因为kh这个音很难发出？
