Apostrophe After Z Rules

teacher demonstrating the rules for using an apostrophe after z

It’s only an apostrophe…how tricky can it be? We’ll follow these simple rules and it can be quite simple! The English language is full of unique punctuation rules. There are even punctuation rules that apply to individual words. For example, there are rules on how to punctuate “however” correctly in your writing.


1) Make It Plural

To make a word ending in Z plural, you need to add “es”. Here are some examples to illustrate this rule:

  1. Singular: The teacher gave me my quiz. Plural: The teacher handed out quizzes to the entire class.
  2. Singular: Mark Sanchez is coming over for dinner. Plural: The Sanchezes are coming over for dinner.
  3. Singular: Mr. Santinez drove to the grocery store to grab dinner. Plural: The Santinezes drove to the supermarket to grab dinner.

Rule: Add “es” to words or proper nouns ending in Z to make them plural.


2) Singular Possession

To transform a singular noun into the possessive form, add an apostrophe & “s” after the z. Here are some examples:

  1. Singular: Chaz has a beautiful cat. Singular Possessive: Chaz’s cat is the most beautiful cat in the world.
  2. Singular: Sanchez owns a baseball bat. Singular Possessive: Sanchez’s baseball bat is the most expensive on the entire team.
  3. Singular: Martinez drives to work every day in a red car. Singular Possessive: Martinez’s bright red car stands out like a sore thumb in the parking lot.

Our post about the word business’s showed how the apostrophe should be used in this case!

Rule: Add ‘ + S after the z to create singular possessive nouns.


3) Plural Possessive Form

There is a two-step process to creating the plural possessive form of a noun ending in z:

  1. Add es after the Z to make the noun plural
  2. Add the apostrophe

Here are some examples:

  1. Plural: The Hernandezes are coming over for dinner. Plural Possessive: The Hernandezes’ chicken is the best-tasting food in California.
  2. Plural: The Diazes are the best fighters in the UFC. Plural Possessive: The Diazes’ merchandise is the most popular with UFC fans.
  3. Plural: The Sanchezes are the richest family in Oaklahoma. Plural Possessive: The Sanchezes’ car collection is the most impressive in the state of Oklahoma.

Remember, spelling is just as important as punctuation. People who play crossword and scrabble might ask, is axel a scrabble word? The answer is yes. But don’t confuse the spelling with axle.

Rule: Add just an apostrophe to make the plural noun into the possessive form.


Additional Examples

  1. If you wanted to indicate that Mr. Hernandez owned a bag of apples, you might say “Mr. Herdandez’s bag of apples.” In this example, the original proper noun is Mr. Hernandez, and the correct proper noun is Mr. Hernandez’s.
  2. The Sanchezes are coming over for dinner. In this example, we added es after the Z to form the plural form of the noun. This is the correct form as it indicates that more than one member of the Sanchez family was coming over for dinner. No apostrophe after z is required.
  3. The Vasquezes’ dogs are the most annoying in the neighborhood. In this example, the apostrophe was used to show plural possession.

You can also look at the words doctor or doctor’s appointment. Adding a single apostrophe can make a huge difference!

History of Possessive Apostrophe

The apostrophe is far from a new syntax or grammatical concept.

The apostrophe was originally used in English to indicate possession and ownership. However, over time its use has evolved and it is now often used to replace omitted letters in contractions (e.g. “can’t” = cannot).

The apostrophe originated from Old English and is still very popular today. Just like in the old days it is used for:

  • Create plural nouns
  • Show possession
  • Create contractions

When it comes to creating possession, we usually add an S before or after the apostrophe. This depends on a variety of factors such as the word’s ending and tense.
