兩者都有“每個”的意思,但用法不同：
（1）each具有名詞和形容詞的功能,every只有形容詞的功能.
（2）each指兩個或兩個以上的人或事物中的“每個”；every是指三個以上的人或事物的“全體”,和all的意思相近.如：
He gave a book to each of his parents.
他給他父母各送了一本書.
Every comrade was there and each did his work.
每個同志都在那兒,各人做各人的工作.
（3）every總是修飾單數(shù)名詞,后接單數(shù)動詞.
Every man and woman knows that.
每個男人和女人都知道那事.
（4）each作為形容詞,修飾單數(shù)名詞,接單數(shù)動詞.作為代詞,單獨使用,接單數(shù)動詞；放在復(fù)數(shù)名詞和代詞后作同位語,接復(fù)數(shù)動詞.each of them后可接單數(shù)或復(fù)數(shù)動詞.如：
Each man carries his own bag.（修飾單數(shù)名詞）各人背自己的包.
We each have our own office.(作We的同位語)我們各有各的辦公室.
Each carries his own bag.(代詞)各人背自己的包.
Each of them are/is here.(代詞)他們每個人都在這兒.
（5）代表each和every的物主代詞可以用his,也可以用their.如：
