Question

Could you tell me when will you come here .正确吗？

Answer 1

Could you tell me when will you come here .正确吗？
不对，应该是：
Could you tell me when you will come here ？
陈述句when will you come here 被作为间接引语时，只把疑问词when提前，其他部分按陈述句词序排列就可以了，主语与助动词will不用对调位置。

Answer 2

Could you tell me when you will come here?这种疑问句式，像when后面的句子要转变成陈述语序。

Answer 3

不对
