What Is the Grocer's Apostrophe?

The Quick Answer
A grocer's apostrophe is a spelling mistake caused by placing an apostrophe before the s of a plural word.

Do not be tempted to use an apostrophe just because a word ends in "s." For example:
  • Two cats
    • (This is the plural of "cat.")
  • Two cat's
    • (This is not the plural of "cat.")
This error occurs with verbs too:
  • Time flies
  • Time fly's
Apostrophes are used to show possession (e.g., the cat's dinner) or to replace missing letters (e.g., don't).

The Grocer's Apostrophe

A grocer's apostrophe is a spelling mistake caused by placing an apostrophe before the s of a plural word. In English, the plural form of a word is most commonly shown by adding an s to the end (e.g., "cats," "bananas," "pictures"). Don't add your own apostrophe!

In other words, do not add 's to the end. Just add s.

The plural forms of words ending in vowels (e.g., "video," "patio") are extremely prone to this error. Forming a plural by adding 's is a common mistake, and it is considered a grammatical howler.

Examples of Apostrophe Errors

Here are some examples of writing mistakes involving apostrophes:
  • Dog's look up to us, and cat's look down on us. I prefer pig's — they treat us as equal's. (badly transcribed version of a Winston Churchill quote)
  • Anteater's prefer termite's to ant's.
  • Pearl's melt in vinegar.
  • Rent two video's for the price of one.
  • Three large male lion's approached the 4x4.
  • Snow White and the Seven Dwarf's.
    • ("Dwarfs" or "dwarves" would have been okay here, but not "dwarf's" or "dwarve's.")
