We use each to refer to individual things in a group or a list of two or more things. It is often similar in meaning to every, but we use every to refer to a group or list of three or more things.
We use adverbs such as almost, practically and nearly with every, but not with each:
Almost every car in the car park was new.
Not: Almost each car …
Practically every house now has at least two televisions.
Not: Practically each house …
We can use each of + pronoun or each of + determiner + noun, but with every we must use every one + pronoun or every one + determiner + noun:
Each of us has a bicycle.
Every one of us has a bicycle.
Not: Every of us …
Each of the children received a special gift.
Every one of the children received a special gift.
Not: Every of the children …
