The Main uses of Apostrophes To create possessives of nouns. To show the omission of letters. To indicate certain plurals of lowercase letters
Creating Possessives Of Nouns to make a possessive, turn the phrase around and make it an "of the..." phrase. Such as: the girl’s dress = the dress of the girl /or four days’ drive= drive of four days if the noun after “of” is a building, an object, or a piece of furniture, do not use a apostrophe : room of the hotel= hotel room Then follow the rules : Singular form of a word add ‘s even if it ends is s. the owner’s car Plural forms that don’t end in s need to add ‘s. / the herd’s food. Add ‘ to the end of plural noun that ends in s / two cats’ toys Add ’s to the enad of compound words./ my father-in-law’s money. Add ‘s to the last noun to show joint possession of an object. /Todd and Anne’s dorm
Showing omission of letters Apostrophes are used in contractions. Contractions are common in speaking and in informal writing. Words such as / don't = do not /I'm = I am he'll = he will/ who's = who /didn't = did not They take the place of letters and combine words.
Forming plurals of lowercase letters Apostrophes are used to form plurals of letters that appear in lowercase; here the rule appears to be more typographical than grammatical, e.g. "three ps" versus "three p's." To form the plural of a lowercase letter, place 's after the letter. Nita's mother constantly stressed minding one's p's and q's.
When not to use apostrophes Don't use apostrophes for personal pronouns, the relative pronoun who, or for noun plurals. Wrong: his’ book. who’s dog is this? Correct: his book. whose dog is this?
