Apostrophe rules are not as confusing as you think. Once you know the fundamental guidelines on their placement, you’ll be able to answer, where should the apostrophe go?
Keep reading to learn when to put an apostrophe before s. I also provided examples of how to use the apostrophe and s in a sentence.
Why Put an Apostrophe Before S?
The two main reasons we put apostrophes before S are to show contractions and possession. These are the most common apostrophe functions besides indicating the plural of letters, numbers, and symbols.
A possessive apostrophe has a letter S (‘s) after it to show that someone or something owns an item or is a member of something.
Here are some examples of ‘s in a sentence:
- Margaret’s new mirror has brown edges.
- Romeo’s motorcycle is lost.
We also use an apostrophe before s to indicate the combination of a word plus “is.”
Here are some examples:
- Lui’s texting Georgia (short for “Lui is texting Georgia”).
- The design on the shirt’s already fading (short for “The design on the shirt is already fading”).
When to Put an Apostrophe Before S and When to Put it After
One question that many English writers have when showing ownership is, where should the apostrophe go?
Use an apostrophe before s (‘s) if the noun is singular.
- The ant’s food storage.
- Jamie’s wine cellar.
You can also use an apostrophe before s (‘s) for irregular plural nouns that do not end in s.
- Men’s bathroom.
- People’s cry.
When the singular noun ends with S or Z but has one syllable, use apostrophe + s (‘s).
- Mars’s moons.
- Ross’s tumbler.
Note that some style guides do not recommend this rule. That means “Mars’ moons” and “Ross’ tumbler” may also be acceptable.
Be sure to have an apostrophe after the S (s’) at the end of regular plural nouns.
- The parents’ bedroom.
- The Johnsons’ home.
You should also use an apostrophe after the S (s’) for multi-syllable singular nouns that end in S.
- Fiberglass’ cracks.
- Gambas’ seasoning.
