I think these changes would improve your letter.

Hello every one!
My name is Edilson and I don't Know if it is correct to use this post!If I'm wrong somene please tell me.
I would like to know what means this sentence "the backbone so to speak"?
So, that is it for now and thanks!

Hello Edilson,

Welcome to the forums!

I'm afraid your snippet is not a complete sentence so it's only possible to guess at the meaning.

I think that it is part of a sentence which is speaking about the main structure of something.

Hello Beesnees!

So Sorry!

Then it is here the full sentence.

But the most important thing -- the backbone so to speak -- is this CD.

Did the painter say he would finish the work? " No, he.............to tell me"
key: yet hasn't .
I 've never seen such structure when yet stand before has/have + not. S.o help me to explain please!

[Luschen]

Hi Frenzyduonga, was this part of a test or exercise?

The correct sentence would be "No, he has yet to tell me." or "No, he has not yet told me."

As you say, "No, he yet hasn't to tell me" is incorrect.
