79. Nicknames.—Do not quote nicknames of persons or of characters in plays or novels: as, Ty Cobb, T. R., Heinie Zim, Becky Sharp, etc.
9. The Apostrophe
80. Possessive Case.—Use an apostrophe and an s to indicate the possessive case singular, no matter whether the word ends in one or two s's: as, Burns's house, Furness's hat.[51] Use the apostrophe and s to indicate the possessive case plural when the plural does not end in s: as, men's meeting, children's shoes. Use only the apostrophe to indicate the possessive case plural when the plural ends in s: as, boys' hats, ladies' outfitter. In names of corporations, cases of joint authorship, etc., where two names are equally in the possessive case, put the apostrophe, or the apostrophe and s, only after the name nearest the thing possessed: as, Farmers and Merchants' bank, Allen and Bowen's "Classical Mythology."
81. Possessive Pronouns.—Do not use the apostrophe before the s in possessive pronouns: as, its, hers, theirs.
82. Contractions.—Use an apostrophe in contracted words to indicate the omission of letters: as, couldn't, he'll, you're.
[51] Occasional exceptions to this general rule are found, where euphony would be violated by the additional s: as, Ulysses' son, Moses' staff.
