Each vs. Every

Both Each and Every refer to a plural number of items, but there is a slight difference between these determiners:

Each considers each item as an individual unit. If there are only 2 items in a group, you can use Each as a synonym for Both.
Every considers all these items as part of a group. Never use Every as a synonym for Both.

Each vs. Every Tips

If you can add an adverb of degree (almost, practically, nearly and so on) before a determiner, use Every.
If you are talking about events repeated regularly, use Every.
