Each vs. every

[Sultano]

but is there a difference between each one and evey one
every year , each year? and so on...

Hi Sultano,
I think this is the case when "each year" and "every year" have the same meaning, i.e.interchangeable
I also think that every one is the same as each one.

There are cases when both each and every cannot be interchangeable.

As Alan explained, every often gives the idea of 'all', each of an 'individual'

Some examples, taken from the Internet:
Ex.We gave each child who came to the party a present( We handed them out one by one).
Ex.We gave every child who came to the party a present (We gave them all a present).

Also keep in mind that "every" cannot be used to indicate two things.

I agree that there is often little difference in meaning. Nevertheless, each always focuses on the individuals of a group and every focuses on the whole group.

In addition, you can say "each of them" and also "every one of them", but you cannot say "every of them".
