Life of the single polliwog - Using the Apostrophe






















The apostrophe, a flying polliwog of punctuation, often challenges writers. It functions to show possession and becomes a place saver in other situations. It does not form plurals.

Rule 1: To form the possessive of a singular noun that does not end in s or an s sound, add an apostrophe plus s to the noun:

Examples: the writer's pen, John’s pencil, my friend’s book

Rule 2: To form the possessive of a singular noun that does end in s or an s sound, add an apostrophe plus s to the noun:

Examples: Jennifer Lopez's song, the witness's report, James's poetry

One exception to this rule involves using only an apostrophe when adding the apostrophe plus s makes the word difficult to pronounce:

Examples: Sophocles' plays, Mary Rogers' bouquet

Rule 3: To form the possessive of a plural noun that ends in s or es, add only an apostrophe to the noun:

Examples: the teachers' books, the writers' lessons, their friends' papers, the beaches' shells.

Rule 4: To form the possessive of a plural noun that does not end in s or es, add an apostrophe plus s to the noun:

Examples: children's toys, the women's dressing room

Rule 5: To indicate separate possession, add whichever possessive sign is appropriate (an apostrophe plus s or an apostrophe alone) to the name of each person:

Examples: Bill's and Tom's cars (two separate cars: Bill's car and Tom's car), James's and Olivia's houses (two separate houses: James's house and Olivia's house)

Rule 6: To indicate joint possession, add the appropriate possessive sign (an apostrophe plus s or an apostrophe alone) to the final name:

Examples: Mary and John's house (the house belongs to both Mary and John), Edward and Madeleine's books (the books belong to both Edward and Madeleine)

One exception to this rule occurs if one of the owners is identified by a pronoun (my, his, her, our, their). In this case, make each name and pronoun possessive:

Example: Erica's and my project (not Erica and my project); Mark's and our dinner (not Mark and our dinner); John's, Edgar's, Lisa's, and my party (not John, Edgar, Lisa, and my party)

Possessive pronouns: my, mine, your, yours, his, her, hers, its, our, ours, their, theirs, whose. These pronouns never require apostrophes.

Rule 7: To form the possessive of a singular abbreviation, add an apostrophe plus s.

Examples: the AMA's letter, the MD's diagnosis, USA's stand

Rule 8: To form the possessive of a plural abbreviation, add an s'.

Examples: the PhDs' dissertations, the RNs' orders, the CPAs' convention

A note about apostrophes that become place savers in contractions: Whenever a word or phrase becomes shortened by contraction, place an apostrophe at the point where the letters are omitted.

Examples: don't (do not), can't (cannot), rock 'n' roll (rock and roll), ma'am (madam). Confusion occurs when it is turns into it’s. Its color shows the possessive and means belong to it.

Joe parks his car in Terry and Jane's driveway with its blue color. He parks next to the Petersons' house and across the street from Edward's and Alfred's apartments. So, don’t worry, it’s apparent you know how to use the single polliwog of punctuation.
