In my country, although English is not our native language, it is spoken quite a lot. I've heard many a time only being used for emphasis,but I don't think I've ever seen a native using it. Here is an example
You are going there only.
I heard someone using this sentence when they wanted to get something and asked someone to bring it. When that someone refused, they said "You are going there only, what's the problem in bringing it?"
Is this kind of usage acceptable?
