Hi. I'm having difficulty differentiating between the two. I understand that Meaning refers to it making sense, while Structure refers to if it sounds grammatically correct. However, I always find myself marking one with the other. I'm not sure if that's how it should be. I assume it shouldn't be that way. Otherwise, there would be the Visual column and then one column that has Meaning/Structure together as one. Can someone give me a concrete example of an error which would be Meaning, but not Structure, and vica versa? Thanks!
