As you know, when we learned English in China, we referred spoken English as "Oral English", last night, I saw this word appeared somewhere in this forum again. I just couldn't help, but laughed. I asked my hu*****and that if he had ever heard anyone using this term. He laughed, and said "NO" :))) I think, grammatically, "Oral English" is a correct term. But it can make people think of something else...
I am not trying to be mean here, and I am aware that I am not very good in English either, but just remind our sisters/brothers be cautious for certain common usage of words
