tpo7-3阅读中，最后一段有一句话不太明白：
They spoke a language, prior-Bantu (“Bantu” means “the people”), which is the parent tongue of a language of a large number of Bantu languages still spoken throughout sub-Sahara Africa.
其中  parent tongue of a  language of a large number of Bantu languages  怎么理解？？求大神指点，谢谢了

就是说这种语言后面发展了很多分支，他们说的是鼻祖，所以是parent tongue。
