hi there Libby, "each" usually focuses on the individuals of the group while "every" focuses on the whole group. "each performer showed their talent." (the performers showed their talent ONE-BY-ONE). "every performer showed their talent." (ALLthe performers showed their talents) although in some cases, they can be used interchangeably without changing the meaning of the sentence. "each time I see you" = "every time I see you" *** you have to take note also that both "each" and "every" should be used with singular nouns. each day / every day - - - (correct) each days / every days - - - (incorrect) :)

each... = in every of sth every = all of sth it's not the same but similar....~ !
