Hyphens and dashes are punctuation marks that serve different purposes in writing. Understanding how to use them correctly can significantly improve the clarity and professionalism of your writing.
1. Hyphens (-)
A
hyphen is a short horizontal line used to join words or parts of words. It is
essential in forming compound words, linking prefixes to words, and breaking
words at the end of lines.
Functions of Hyphens:
- Compound
Words:
Hyphens are used to join two or more words to form a single idea or
concept. For example:
a)
Mother-in-law
b)
Well-known
c)
Editor-in-chief
- Prefixes: Hyphens link prefixes to
proper nouns or to avoid confusion. For example:
a)
Anti-inflammatory
b)
Ex-governor
c)
Re-enter
- Numbers
and Fractions:
Hyphens are used in written numbers and fractions. For example:
a)
Twenty-one
b)
Fifty-four
c)
One-third
- Adjective-Noun
Modifiers:
When a compound adjective precedes a noun, a hyphen is used. For example:
a)
High-quality
fabric
b)
Long-term
solution
c)
Fast-moving
car
Examples:
·
Amara’s
mother-in-law visited last weekend.
·
The
well-known artist, Chika, showcased her new collection.
·
Sade
will be the editor-in-chief of the school magazine.
·
The
ex-governor attended the community event.
·
Femi
needs to re-enter his password to access the account.
2. Dashes (–, —)
Dashes
come in two forms: the en dash (–) and the em dash (—). They are longer than
hyphens and have distinct uses in writing.
En Dash (–):
The
en dash is slightly longer than a hyphen but shorter than an em dash. It is
primarily used to indicate ranges, connections, or differentiation.
Functions of the En Dash:
- Ranges: To show a span of time, dates,
or numbers. For example:
a)
The
meeting will take place from 2:00–3:00 PM.
b)
The
academic year 2023–2024.
- Connections: To indicate a connection or
contrast between two words. For example:
a)
The
Lagos–Abuja flight.
b)
The
Nigeria–Ghana football match.
Examples:
a)
The
exhibition runs from 10:00 AM–5:00 PM daily.
b)
The
Ibadan–Lagos expressway is always busy during holidays.
Em Dash (—):
The
em dash is the longest of the dashes. It is versatile and can replace commas,
parentheses, or colons for emphasis or to set off information.
Functions of the Em Dash:
1.
Interruption
or Emphasis:
To insert an abrupt break or to emphasise additional information. For example:
a. I know what you’re thinking—this is
amazing!
b. Chinedu—despite his busy
schedule—managed to attend the meeting.
2.
Additional
Information:
To add non-essential information that can be removed without changing the
meaning of the sentence. For example:
a. The ingredients—sugar, flour, and
eggs—are already in the kitchen.
b. Bisi’s favourite hobby—playing the
violin—relaxes her after school.
3.
Lists
within Sentences:
To set off a list within a sentence, especially if the list is complex or
contains internal punctuation. For example:
a. The committee included Amina—a
brilliant strategist—, Kunle—a detail-oriented planner—, and Ngozi—a skilled
negotiator.
Examples:
a)
Olu—a
talented footballer—was awarded the best player of the year.
b)
The
books—mathematics, physics, and chemistry—are available in the library.
c)
Ada
couldn’t believe it—she had won the scholarship!

Hyphens
and dashes, while seemingly similar, serve distinct purposes in writing.
Hyphens connect words and parts of words, forming compound terms and ensuring
clarity in prefixes and numbers. Dashes, both en and em, provide nuanced ways
to indicate ranges, connections, and emphasis in sentences. Mastering the use
of these punctuation marks will enhance your writing skills, making your
communication more precise and effective.
