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.
- Jones's report is terrible.
The Possessive Form of a Plural Noun Ending Z
The plural of a noun ending z is formed by adding es. Sometimes, the z is doubled before the es is added. This is standard. For example:- quiz becomes quizzes
- topaz becomes topazes
- Mr. Lopez is the father of the Lopezes
- The quizzes' origins are well documented. (This relates to "the origins of several quizzes" (i.e., quizzes is plural).)
- The Lopezes' dog has been found. (This relates to "the dog of the Lopez family" (i.e., Lopezes is plural).)
The History of the Possessive Apostrophe
The main function of the apostrophe is to replace a missing letter (e.g., aren't, don't). You might not have realized it, but this is related to the possessive apostrophe. (e.g., Sarah's house, the robbers' haul)In old English, possession was shown by adding "es" to the noun regardless of whether it was singular or plural. For example:
- doges dinner
- dogses dinner
- childrenes dinner
- Sanchezes dinner
