Is It Chris’ or Chris’s?

man thinking if he should use Chris' or chris's

Many people overcomplicate the rules of plural possessive of nouns ending in -S. Nouns are a very important part of speech in the English language. Take Chris for example. In reality, you can use both Chris’ or Chris’s in your writing. The rules are simple.

  • Chris’ – If you are following the Associated Press stylebook (AP Style) [1], add just an apostrophe to plural nouns ending in -S. (i.e. Chris’ car or Chris’ dog)
  • Chris’s – If you are following the Chicago Manual of Style [2], add an apostrophe -S. (i.e. Chris’s house). Used more frequently in British English.

If you’re going to be a stickler for rules, you need to know the rules of plural possessives, just make sure you know the difference between noun vs pronoun. The basic rule is that if you have more than one of something, you need to add an apostrophe s to the end of the word. But the -S is optional depending on which style guides you choose to follow. Name and Me or Name and I is another grammar rule that focuses on pronouns!

Takeaway: Both Chris’ and Chris’s are grammatically correct.

When To Use Chris’?

If your writing assignment follows the rule of the Associated Press Stylebook, write Chris’ to show plural possession.

  • For example: “I am going to catch a ride in Chris’ car.”

When I teach my 7th-grade students…we often teach them that Chris’ is the correct way to write this proper noun. Adding only the apostrophe is the most common way to show possession for proper nouns ending in -S. However, not all proper bounds end in -S. Take the word invision or envision for example.

When To Use Chris’s?

If you follow the teaching of British English or the Chicago Manual of Style then write Chris’s.

  • For example: “I can’t stand hanging out at Chris’s house.”

The truth is…many people don’t like how Chris’s looks in their writing. The back-to-back -S is not common and can seem awkward. However, this possessive case is becoming more and more popular in American English.

Other words follow this exact same grammar rule. Look at the apostrophe in parent’s house for further demonstration of this rule.

Is It Chris’s or Chris’ In UK Grammar Rules?

In UK grammar rules, both “Chris’s” and “Chris'” are considered acceptable forms when indicating possession. The choice between the two depends on personal or editorial preference. The generally preferred style, however, is to use “Chris’s” for singular nouns, even if they end in “s,” to maintain consistency in written expression.

Is It Chris’s or Chris’ In Australian Grammar Rules?

In Australian grammar rules, similar to UK conventions, both “Chris’s” and “Chris'” are considered correct forms for denoting possession. The choice between them often depends on personal or editorial style, with some preferring the additional “s” after the apostrophe for clarity, especially when dealing with singular nouns ending in “s.” Ultimately, writers may choose the form that aligns with their preferred style guide or individual preferences.

What Are The Apostrophe Rules?

There are several apostrophe rules that will come in handy for your writing.

  • Show possession – As in “the cat’s toys” or “the students ‘ID cards.” In these cases, the apostrophe goes before the “s” if the noun is singular (as in “cat”) and after the “s” if the noun is plural (as in “students”).
  • Omit letters – Think of contractions like “don’t” or possessive pronouns like “it’s” (which is short for “it is” or “it has”). The apostrophe is used to show that there is a missing letter
  • Indicate plurals – Depending on the specific style guide you follow, apostrophes can be used to create the plurals of letters, numbers, and symbols ONLY. (Two B’s = two letters that are both B)

Examples of Possessive Nouns

  1. The cats’ toys were spread out all over the room. (The toys belong to more than one cat.)
  2. Steve’s car needs to be washed. (The car belongs to Steve.)
  3. The girls‘ shoes were not present during role call. (The shoes belong to more than one girl.)
  4. We went to the Joneses’ house for dinner. (The house belongs to the Joneses.)
  5. Loyola University’s campus is in Chicago. (The campus belongs to Loyola University.)
  6. Santa Claus’s sleigh is full of presents. (The sleigh belongs to Santa Claus.)
  7. John and Mary’s wedding will be next month. (The wedding belongs to John and Mary.)

Follow The Rules Of Your Style Book

The tricky part of grammar is that there is not a single rule set to follow. In fact, there are several different style guides that have widespread adoption.

  • Publication Manual of the American Psychological Association (APA Style)
  • The Associated Press Stylebook (AP Style)
  • The Chicago Manual of Style (Chicago Style)
  • MLA Handbook (MLA Style)

In reality, different grammar stylebooks simply have different guidelines. So, if you’re ever unsure which rule to follow, just consult your stylebook. In formal writing, there is usually a specific style guide to follow depending on the type of writing. For informal writing, you have more flexibility.

Rules For Singular Nouns

Unlike plural nouns, singular nouns represent one thing. That one thing could be

  • A person
  • A place
  • A thing

To make a singular noun possessive, you usually add an apostrophe and an “s.” For a singular noun ending in -S, you can just add an apostrophe after the “s” to show possession. Both plural and singular nouns ending in -S follow the same rules!
