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

History of Possessive Apostrophe

The apostrophe is far from a new 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.
