each and every: the difference
each with two or more; every with three or more
Each and every are both normally used with singular nouns. Each can be used to talk about two or more people or things; every is normally used to talk about three or more.
- The business makes less money each/every year. (not
… each/every years.) - She had a child holding on to each hand. (not
… every hand.)
For expressions like every two years, every three steps, (see here).
Meaning
Each and every can often be used without much difference of meaning.
- You look more beautiful each/every time I see you.
But we prefer each when we are thinking of people or things separately, one at a time. And every is more common when we are thinking of people or things together, in a group. (Every is closer to all.) So we are more likely to say:
- Each person in turn went to see the doctor.
but
- Every patient came from the same small village.
Structures
We do not use each with words and expressions like almost, practically, nearly or without exception, which stress the idea of a whole group.
- She’s lost nearly every friend she had. (not
… nearly each friend …)
Each can be used in some structures where every is impossible.
- They each said what they thought. (but not
They every …) - Each of them spoke for five minutes. (but not
Every of them …)
For more details, (see here) (each) and (see here) (every).
