• In contemporary standard spelling,everyone is used when it can be replaced witheverybody, whileevery one is used when it can be replaced witheachone. Most importantly, this means thateveryone is only used of persons. The two-word formevery one should still be used of persons when it refers separately to the members of a group specified in the context (as in the second example above), although this distinction is seldom relevant for the sense.
