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.

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.

Examples

You can granularly configure rules for each media set.
You can view properties of each tape registered in the database.
