Etymology

Origin of apostrophe1

1580–90; < Middle French (with pronunciation later altered by confusion with apostrophe 2 ), replacing earlier apostrophus < Late Latin (> Middle French ) < Greek apóstrophos ( prosōidía ) eliding (mark), literally, (mark) of turning away, verbid of apostréphein to turn away, equivalent to apo- apo- + stréphein to turn; see strophe

Origin of apostrophe2

1525–35; < Late Latin < Greek apostrophḗ a turning away, equivalent to apostroph- (verbid of apostréphein; see apostrophe 1) + noun suffix

Explanation

An apostrophe is a punctuation mark used in contractions to replace missing letters. The contraction "we'll" stands for "we will," with the apostrophe replacing "wi." It can also show possession, as in "Mary's car." The apostrophe indicates the car belongs to Mary. To correctly pronounce apostrophe, accent the second syllable: "uh-POSS-truh-fee." In addition to being a punctuation mark, apostrophe can also be a literary device in which the speaker of a poem talks to someone who is not there. A famous example of this is Walt Whitman's "O Captain! My Captain!" in which he addresses the deceased Abraham Lincoln: "O Captain! my Captain! rise up and hear the bells."
