英译汉，或者汉译英，关于语法的问题

I can't say anthing only goodbye for you 有没有语法错误，如果有的话，正确的应该是什么， PS： 我没有什么要说的，只能对你说再见

I can't say anything but goodbye to you.

I can't say anything but goodbye.

I have nothing to say but goodbye.

我只能对你说再见。

i have nothing to say ,but goodbye 这才是对的，，

i can't 是我不能干嘛干嘛，，，，

懂了不？

I can't say anthing only goodbye for you 口语可以，口语有时候语法不标准。

I can't say anthing to you but goodbye

I can say nothing to you but goodbye

这两个都可以。to you也可以放在句末
