each and every one

Also, every last one; every single one. Every individual in a group, as in Each and every student must register by tomorrow, or I've graded every last one of the exams, or Every single one of his answers was wrong. All of these phrases are generally used for emphasis. The first, although seemingly redundant, has replaced all and every, first recorded in 1502. The first variant dates from the late 1800s, and both it and the second are widely used. Also see every tom, dick, and harry. Every mother's son (late 1500s) and every man Jack (mid-1800s) are earlier versions that refer only to males.
