WORD CHOICE: each, every
It is often correct to use either each or every , but they have slightly different meanings.
Use each when you are thinking about the people or things in a group separately, one by one : Each student came forward to receive a medal (emphasizes that they came forward one after another) | Each time you Exercise, you get a little stronger.
Use every when you are thinking about the whole group of people or things together, with no exceptions : Every student was given a prize (emphasizes that everyone in the group got a prize) | Warm up every time you Exercise.
!! Do not use each with words such as 'almost', 'nearly', or 'not'. Use every : Almost every window was broken. | Not every child enjoyed the party.
!! Do not use each in negative clauses. Use none : None of the answers were correct (NOT Each of the answers were not correct).
GRAMMAR
each and every are followed by a singular verb : Each item was thoroughly checked. | Every member wears a uniform.
each and every are usually followed by a singular pronoun or determiner (he, she, it, his, himself etc) : Each component can be replaced separately if it breaks. | Every woman must decide for herself.
But you can use 'they', 'them', 'their' etc when you do not want to say whether people are male or female : Every child has their own room.
