Mastering Apostrophes and Hyphens: Common Mistakes and Usage Tips
Have you ever stared at a word in a document you’re writing,
wondering if you need an apostrophe or if the two words should be connected
with a hyphen? You're not alone. These tiny punctuation marks can cause confusion
for writers at all levels. In this article, we demystify apostrophes and
hyphens, saving you from embarrassing mistakes and helping you write with
clarity and confidence.
Understanding Apostrophes
An apostrophe is a punctuation mark used to indicate
possession. The apostrophe may be small, but it holds significant meaning in
written documents. Clearly understanding its uses will help you improve your
writing.
Two Main Uses
Apostrophes serve two primary functions:
- Showing
possession
- Sam's
book (the book belongs to Sam)
- Sam’s book is on the
table.
- The cat's
toy (the toy belongs to the cat)
- The dog is playing with
the cat’s toy.
- The
children's playground (the playground belongs to the children)
- I heard laughter from
the children’s playground.
- Indicating
a contraction
- Don't
(do not)
- The books don’t look too
long.
- She's
(she is)
- She’s on top of the
world.
- They're
(they are)
- They’re all at the party
together.
These rules seem simple, but it can be hard to know the spelling
of words using a contraction. Confusion can also arise when dealing with plural
possessives or words that already end in "s."
Singular possessive:
- The
cat's toy (one cat)
- The
cat’s toy is in the corner by the dog’s bone.
- James's
car (belongs to James)
- I
left my coat in James’s car.
Plural possessive:
- The
cats' toys (multiple cats)
- The
cats’ toys are in the corner by the dog’s bone.
- The
Smiths' house (the family named Smith)
- We
went over to the Smiths’ house yesterday.
Pro Tip:
For singular proper nouns ending in
"s" (like James), style guides differ. Both James' and James's are
acceptable depending on which style guide you follow. The important thing is to
be consistent within a single document. For example, if you’re writing an
article and follow a style guide that recommends using James’ as the possessive
form, be sure to use that form throughout the document.
Real-Life Apostrophe Mistakes
Let's examine some apostrophe errors commonly seen in the
“real world”:
1. The Greengrocer's Apostrophe
This apostrophe is named for a common mistake seen on
produce signs. The error involves adding apostrophes to basic plurals:
❌Incorrect:
"Fresh lemon's
for sale"
✅Correct:
"Fresh lemons for sale"
2. Its vs. It's Confusion (see
Its
vs. It’s
for more details)
Misunderstanding its versus it’s is a common apostrophe
mistake:
❌Incorrect:
"The dog
lifted it's leg."
✅Correct:
"The dog lifted its leg." (possessive pronoun)
❌Incorrect:
"Its
going to rain tomorrow."
✅Correct:
"It's going to rain tomorrow." (contraction of
"it is")
Remember that "it's" ALWAYS means "it
is" or "it has." If you can't substitute one of those two phrases,
you should use "its."
3. Decades and Acronyms
Another frequent apostrophe error occurs when the writer
needs to pluralize decades or acronyms:
❌Incorrect:
"This is
popular music from the 1990's."
✅Correct:
"This is popular music from the 1990s."
❌Incorrect:
"I have
several DVD's in my collection."
✅Correct:
"I have several DVDs in my collection."
4. Company Names
Many businesses make intentional style choices with
apostrophes, but technically:
❌Common but technically
incorrect:
"McDonald's" (if referring to multiple McDonald restaurants)
✅Technically correct:
"McDonald's is a popular restaurant."
(referring to the company as a singular entity)
What Is a Hyphen?
A hyphen (-) is a punctuation mark used to join words or
parts of words. Shorter than both the en dash (–) and em dash (—), the hyphen
connects compound terms and breaks words at the end of a line of text.
When to Use a Hyphen
Knowing when to use hyphens can dramatically improve your
writing clarity. Here are the primary situations when hyphens are required:
1. Compound Modifiers Before Nouns
When two or more words work together to modify a noun, they
often need a hyphen:
- Well-known
singer
- State-of-the-art
gymnasium
- Eight-year-old
child
However, when these modifiers come after the noun, they
typically don't need hyphens:
- The singer
is
well known
.
- The gymnasium
is
state of the art
.
- The
child is eight years old.
2. Compound Numbers and Fractions
With the exception of certain style guides, hyphens are generally
used in written-out numbers from twenty-one to ninety-nine and fractions:
- Twenty-two
students
- Forty-six
minutes
- Two-thirds
majority
3. Prefixes
Some prefixes require hyphens, especially:
- With
proper nouns:
anti-inflammatory
,
pre-kindergarten
- With
self-:
self-respect
,
self-control
- To
avoid confusion:
re-cover
(to cover again) vs.
recover
(to
get better)
- With
ex-, all-:
ex-wife
,
all-inclusive
4. Avoiding Ambiguity
Hyphens clarify meaning when words could be misinterpreted:
- A
small-business
owner
(owner of a small business)
- A
small
business owner
(could be interpreted as a business owner who is small
in stature)
Common Hyphen Mistakes
1. Confusing Hyphens with En Dashes and Em Dashes
❌Incorrect:
"The
meeting will run from 1-3 PM."
✅Correct:
"The meeting will run from 1–3 PM." (This time frame requires
an en dash instead of a hyphen)
2. Hyphenating Adverb-Adjective Combinations
❌Incorrect:
"It was
a highly-rated event."
✅Correct:
"It was a highly rated event." (No hyphen needed with
-ly adverbs)
3. Inconsistent Hyphenation
❌Incorrect:
"She is
a well-respected, high profile expert."
✅Correct:
"She is a well-respected, high-profile expert." (Be
consistent with similar constructions)
4. Unnecessary Hyphens with Prefixes
❌Incorrect:
"The
pre-existing condition"
✅Correct:
"The preexisting condition" (Most prefixes don't
require hyphens)
The use of hyphens
varies with prefixes. Generally,
prefixes like "pre," "post," "non,"
"anti," and "re" don't need hyphens, but exceptions exist when
there’s a need to avoid confusion or awkward combinations.

Frequently Asked Questions
What is a hyphen used for in everyday writing?
A hyphen joins words to form compound terms or breaks a word
at the end of a line. In everyday writing, hyphens most commonly appear in
compound modifiers (e.g., "user-friendly software"), certain prefixed
words (like "self-respect"), and written-out numbers between 21 and
99.
When is a hyphen used with compound modifiers?
Use a hyphen with compound modifiers when they appear before
the noun they modify. For example: "state-of-the-art technology,"
"full-time job," or "blue-green eyes." However, when these
same modifiers appear after the noun, they typically don't need hyphens:
"The technology is state of the art."
When is a hyphen used for prefixes like "pre"
and "re"?
Most prefixes don't require hyphens (e.g., restart), but hyphens
should be used in some cases: proper nouns (e.g., pre-Victorian); to avoid
confusion (re-sign, or sign again vs. resign or quit; with self-, ex-, and all-
(e.g., self-respect, ex-partner, all-inclusive); when the prefix ends with the
same letter the word begins with (e.g., anti-inflammatory, co-owner).
What are the most common real-life apostrophe mistakes?
The most common apostrophe errors include: using apostrophes
in basic plurals (orange's instead of oranges); confusing its (possessive) with
it's (contraction of "it is"); incorrect placement in plural
possessives (the Smiths' house, not the Smith's house for the entire family);
and misusing apostrophes in acronyms and decades (DVDs, not DVD's; 1980s, not
1980's).
Is it "James's car" or "James' car"?
Both forms can be correct depending on which style guide you
follow. Traditional guides like Chicago Manual of Style recommend "James's
truck," while some journalistic styles prefer "James' truck." The
important thing is to be consistent throughout a document.
Can hyphens change the meaning of a word or sentence?
Yes! Consider this example: “Thirty odd people attended”
(approximately 30 strange people) versus “Thirty-odd people attended” (a bit
more than 30 people attended).
Conclusion
Mastering apostrophes and hyphens might seem like a small
detail, but these punctuation marks can significantly impact the clarity and
professionalism of your documents. By understanding when to use these marks and
avoiding common mistakes, you'll write with greater confidence and precision.
Remember these key takeaways:
- Apostrophes
show possession or indicate contractions—never use them for simple plurals.
- The use
of a hyphen depends primarily on compound modifiers, certain prefixes, and
instances where clarity is needed.
- When
in doubt about hyphens, consult a current style guide or
expert.
