Use an apostrophe to form the possessive of singular and plural nouns Joe + ’s= Joe’s Car flag + ’s = flag’s colors Day + ’s = day’s effortglass + ’s = glass’s cost Note: if a PLURAL noun ends in s, just add an apostrophe Cars + ’ = cars’ interiors Televisions + ’ = televisions’ locations Note: if a plural noun does NOT end in s, add an ‘s to the word. Mice + ’s = mice’swomen + ’s = women’s

Exception Alert!! If a name of two or more syllables ends in an “eez” sound, the possessive is formed WITHOUT an additional s The tales of Ulysses = Ulysses’ tales The speech of Orestes = Orestes’ speeches The cancellation of the TV series = the TV series’ cancellation. 2 or more syllables ending in an “eez” sound! Series = (seer-eez)

When the names of two or more persons are used to show joint ownership of the same thing, only the name of the last person mentioned is given the possessive form. Jackson and Myer’s law firm (they share the same law firm) Becky and Jenny’s friend (they share the same friend) Pete and Ken’s iPod. (they share the same iPod) Mrs. McIntyre and Mrs. Gerardy’s classroom (they share the same classroom)

An apostrophe indicates that a number or letter has been omitted (taken out) It is = it’s 1965 = ’65 Does not = doesn’t We will = we’ll It will = it’ll That is = that’s

Tips for checking if something is possessive Another way to think about this rule is to see whether the word of expresses what you're trying to say. With the of method, you note –The children's mother phoned = the mother of the children phoned. –the sharp tooth of the crocodile = the crocodile's sharp tooth –the peanut-stained tooth of the elephant = the elephant's peanut- stained tooth –This is Marmaduke's house = it is the house of Marmaduke.

Sometimes, no clear owner seems present in the phrase. Such a situation arises mostly when you're talking about time. If you can insert of into the sentence, you may need an apostrophe. To give you an idea of how to run the "of test," here are some phrases that express time: These examples are showing time and amount as adjectives to describe how long or how much. If that is happening, you need to use an apostrophe. –Three months' work = the work of three months. (how much work? Three months is being used as an adjective to describe how much) –one week's tooth cleaning = one week of tooth cleaning –a year's dental care = one year of dental care –Does not work: She was 6 months old = six months of old does not work
