I have a grammar question. Consider the following sentence. "The dog of Chris ate the food." Alright, because this sentence sounds awkard (and it's a way of avoiding the grammatical problem I have) would it be, "Chris' dog ate the food," or "Chris's ate the food." As a young child in grade schools in the 1980's I was taught that if there was already an s, you simply inserted an apostrophe. I have seen it written with an extra s lately. Which is way the correct way now? Is there a difference between U. S. and British English here? Thanks!
