The Apostrophe

Apostrophes are more commonly omitted than misused. Perhaps because we do not speak with apostrophes, many people neglect to use them in writing. Another reason for neglect and sometimes error, particularly with plural possessives, may be confusion over where to put the apostrophe and when to add an s. Apostrophes are used to form possessives and contractions.

Apostrophes and Possessives

Here are a few simple rules for using the apostrophe to show possession.

  • Add ' s to singular nouns that do not end in s

    This is the most common form of possession. Add 's to a noun or indefinite pronoun to make it possessive.

Bishop's score mounted steadily, unhampered by the need for corroborative evidence.

What occurred during that famous dawn raid is anyone's guess.

  • Add 's to most singular nouns that end in s

    In most cases, an 's is added to show possession in single nouns that end in s or ss.

Cpl Collins's memo was a detailed brief of the meeting.

Major Munsch stared hungrily at the Mess's lunch menu.

Traditional practice avoids the 's when forming possessives for certain classical and biblical names that end in s: Jesus' disciples, Moses' rod, Achilles' shield, Ulysses' adventures.

Moreover, there is no agreement among editors and grammarians on how to show possession for a proper nouna nameending with a letter that is sometimes given an s soundan x or z. Typically, when speaking we do not pronounce the possessive s in names that end with an s sound. Editorial practice in the Canadian Military Journal is to use 's to indicate possession for such proper names.

Karl von Clausewitz's 1832 treatise, On War, pioneered modern strategic analysis.

  • Add only an apostrophe to plural nouns that end in s or es

    Indicate possession in a plural noun ending in s or es by simply adding an apostrophe after the s.

The soldiers' cameraderie in the trenches of the First World War is a much-celebrated part of Canadian military history.

Our regiment was given only two weeks' notice of the deployment date.

  • Add 's to plural nouns that do not end in s

    A small set of English words, many derived from Latin, have plural forms that do not end in s. The most common of these are media, data, criteria, phenomena, men, women, children, mice, and sheep. To form possessives of these plural nouns, add 's.

It is vital that the military understand and respect the media's role as the principal conduit of information to the Canadian people.

  • Add 's to each word when two or more words show individual possession

    When each word or person possesses different qualities, make each term possessive.

Targeting Iraq's and Afghanistan's industrial capabilities is lawful only to the extent that those capabilities are a valid military objective and the attack meets the requirements of proportionality.
[Each country has different "industrial capabilities," so each requires an 's.]

  • Add 's to only the last word when two or more words show joint possession

    When they both possess the same thing, closely linked nouns are considered a single unit when forming a possessive, as in the title of the popular adolescent fantasy film, Bill and Ted's Excellent Adventure.

General Grant and General Lee's mutual dislike was well known in political circles.

Common Apostrophe errors

Certain words, such as possessive pronouns, are already in possessive form without the aid of an apostrophe. Never use their's, our's, your's, or her's. These words do not exist.

Help! If you have a problem recognizing when and how to use an apostrophe to show possession, try this simple test. Reword the sentence with the suspect possessive using the word of to show that something belongs to somebody or something. You'll need to reorder some of the words to accomplish this. If you can add an of phrase without affecting the meaning of the sentence, then the object of the of phrase needs to have an apostrophe in the original sentence.

The soldiers rucksack fell off the back of the truck.
(Do you need an apostrophe here?)

The rucksack of the soldier fell off the back of the truck.
(The of test works, so indeed you do.)

The soldier's rucksack fell off the back of the truck.
