Apostrophes after Z (with Examples)

Apostrophes after Z

This page is about whether to use 's (apostrophe s) or just ' (just an apostrophe) to show the possessive form of a noun that ends -z. In other words, it is about whether to write:

Gomez' attitude or Gomez's attitude

Forming the Possessive with a Noun Ending Z

Here is the answer:
Use 's to show the possessive form of a singular noun ending -z.
  • Gomez' attitude
  • Gomez's attitude
This question often arises when writers need to form a possessive from a surname ending -ez. For example:
  • Gomez's ball
  • Gonzalez's house
  • Gutierrez's brother
  • Hernandez's dog
  • Lopez's way
  • Perez's garden
(NB: With Hispanic surname, the suffix –ez means "descendant of.")

Why Is There Confusion over Z's and Z'?

Confusion arises because the possessive form of singular nouns that end s (e.g., Moses, series, Wales) can be shown by adding 's or just '.

The general rule for those nouns is write their possessive forms how you would pronounce them. For example:
  • Jones' report is terrible.
  • (This is for those people who pronounce it Jones.)
  • Jones's report is terrible.
  • (This is for those people who pronounce it Jonesiz.)
With the possessive form of a noun that ends in z, there is no choice. It will have the ziz sound at the end. Therefore, the -z's ending is needed to tell readers how to pronounce it.
