\u201cEach\u201d and \u201cevery\u201d are both determiners. They also both refer to something as singular. They are even interchangeable in some cases! As such, it\u2019s not surprising that people mix them up sometimes. However, these terms also have slightly different uses, so you need to be careful to avoid errors.\nEach vs. Every (Groups of Three or More Things)\nBoth of these terms can be used to refer to a group of people or things. For example:\nWe were told to read each book on the list.\nWe were told to read every book on the list.\nIn this case, both sentences imply reading all of the books on the list. The only difference is that \u201ceach\u201d makes us think of reading the books one by one, while \u201cevery\u201d makes us think of them collectively.\n\nBut this only works when the group comprises three or more things. And the difference between these terms becomes obvious if we apply them to a group of two things.\nEach vs. Every (Two Things)\nIf you are referring to two people or things, the word you will need is \u201ceach\u201d:\nHe had an apple in each hand. \u2713\nHe had an apple in every hand. \u2717\nThe first sentence here implies that someone is holding two apples. The second sentence, by comparison, suggests that we\u2019re dealing with some kind of many-handed octopus man.\n\n[caption id="attachment_4464" align="aligncenter" width="293"] Or possibly a Hindu deity.[\/caption]\nEvery vs. All\nSince it is used for larger groups, \u201cevery\u201d is like the word \u201call\u201d in that both terms refer to a group of three or more things collectively. However, \u201cevery\u201d is only ever used with singular countable nouns, while \u201call\u201d is used with plural nouns or uncountable nouns:\nEvery alpaca deserves a hug.\nAll alpacas deserve a hug.\nIf we compare the sentences above, we can see the differences: \u201cevery\u201d is used with a singular noun and a singular verb; \u201call\u201d is used with a plural noun and plural verb. So while thinking of \u201cevery\u201d as a synonym for \u201call\u201d can be helpful, you still need to combine it with singular terms.\n\n[caption id="attachment_4463" align="aligncenter" width="365"] Hug me![\/caption]\nEach and Every?\nFinally, a quick note on the phrase \u201ceach and every.\u201d Some people combine these terms as a form of emphasis when referring to larger groups. This is fine, but it is technically a redundant expression. You should not therefore use \u201ceach and every\u201d in formal writing (e.g., a college paper).
