I noticed in another thread that Clive mentioned that written and spoken english differs (I took this to mean the grammatical structure of each). Could I know some examples of these? I've always assumed the rules were the same for english period, but it would appear not. Oh, and just formal english, please.
Well, I can't speak for Clive, but I have my own thoughts on this.

When we speak, we don't always follow the rules very carefully. Sometimes what "sounds right" isn't truly right. One example of this is saying "It's me!" when by the strict laws of grammar, it should be "It is I."

Also, when you are speaking conversationally, you don't usually plan out where your sentence is going - you just have an idea you want to express and you might have to "change tracks" to get there. If you've ever read transcripts of actual dialogue you'll see what I mean. Speaking (conversationally) is less formal - often FAR less formal - than written English. (I would think that this applies in other languages too!)

So, you said "just formal English" (I took the liberty of capitalizing for you), and if you mean truly formal speaking situations, such as giving an address or the President's State of Union speech, you won't find the differences, but that's because someone wrote it all down in advance.

I think that "spontaneously spoken formal English" probably doesn't exist, at least not for most of us.
Hi guys,

I've nothing to add.
