An appositive with its adjuncts should be set off by the comma.

Notice that it takes two commas to set off an expression that does not come at the beginning or at the end of a sentence. Notice also that a dash as well as a comma is sometimes used to set off a series of apposi-tives.

Exceptions

(1) An appositive that has come to be so closely connected in thought with the noun or pronoun to which it is added that the two seem to form a single title is not set off; thus, John the Baptist, William the Conqueror, We girls.

(2) You have seen (Exercise 122) that in the expressions each other and one another the pronouns each and one are appositives of preceding words. Since they are not placed in the ordinary position of the appositive, they are not set off.

Notice the punctuation of the appositives in Exercise 122. Which appositives are not set off?
