This document discusses the proper use of apostrophes in contractions and to show possession. It explains that for singular nouns, an apostrophe plus "s" is added to show possession. For plural nouns ending in "s", only an apostrophe is added, while other plural nouns add an apostrophe plus "s". Examples are provided to illustrate possessive forms for both singular and plural nouns.
