Punctuation marks are not just symbols designed to make our writing aesthetically pleasing. Rather, they exist to ensure clarity, coherence, and ease of understanding. Much of what makes a writer appear professional is knowing when and where to use punctuation marks correctly.

For poets, punctuation marks are used mainly for effect—for the rhetorical impact they create on the reader. A poet is at liberty to use punctuation in whatever way best serves the poem. In fact, using punctuation is not compulsory in poetry. Many poems have no punctuation marks at all, while others rely on spacing and line breaks to achieve the desired effect. Classical African poetry, however, often employs punctuation skillfully. Some poets known for this include Christopher Okigbo, Léopold Sédar Senghor, Dennis Brutus, Birago Diop, David Diop, Kwesi Brew, and Wole Soyinka, among many others.

A classic line from Christopher Okigbo’s Labyrinths, in “The Passage,” reads:

“Before you, Mother Idoto, / naked I stand; / before your watery presence, / a prodigal.”

The comma and semicolon help create pauses that place rhetorical emphasis on the speaker’s relationship with Mother Idoto and on the final word, prodigal. Similarly, in Senghor’s In Memoriam, the line “at their feet my dead are sleeping, all my dreams made dust” uses a comma to interrupt the rhythm and draw attention to the emotional weight of the concluding phrase.

The prose writer, on the other hand, uses punctuation primarily to ensure clarity and smooth comprehension. A misplaced punctuation mark can completely alter the meaning of a sentence. Consider these examples:

“Doctor, Bill is dead.”

“Doctor Bill is dead.”

In the first sentence, the speaker is addressing a doctor to inform them that Bill has died. In the second, the person who has died is Doctor Bill. A simple comma changes the meaning entirely. There are many such examples, and history even records instances in which punctuation errors caused confusion with serious consequences.

Therefore, punctuation marks are crucial in everyday writing. In speech, punctuation is only implied through pauses, changes in pace, and intonation. Even then, listeners cannot always tell whether a pause represents a comma, a semicolon, or another punctuation mark. This is why punctuation is far more significant in writing than in speech. It plays a vital role in effective communication.

Some of its major functions include:

• Enhancing understanding: Punctuation helps readers understand exactly what the writer intends. Using the example above, the reader can tell whether the sentence refers to Bill or to Doctor Bill. Punctuation marks such as the semicolon also help organise related ideas.

• Creating effect: This is especially common in poetry and expressive writing. Punctuation can reinforce emotion and tone. Compare “A goal!!!!!” with “A goal.” The first conveys excitement, while the second sounds restrained or matter-of-fact. Likewise, compare “Really?” with “Really.” One expresses doubt or surprise, while the other suggests certainty or resignation.

• Showing possession: The apostrophe is used to indicate possession. Consider “Tina’s pen” and “Tina pen.” The first shows that the pen belongs to Tina, while the second simply places the two words together without expressing possession.

• Indicating dialogue and direct speech: Quotation marks are used to show the exact words spoken or written by another person. They distinguish another person’s words from the writer’s own. Omitting quotation marks or failing to acknowledge a source appropriately can amount to plagiarism, which is a serious academic offence.

• Adding extra information: Brackets (parentheses), em dashes (—), and en dashes (–) allow writers to insert additional information without disrupting the main flow of the sentence. These punctuation marks make it possible to expand on an idea while maintaining the coherence of the text.

Writing is beautiful, but without the proper use of punctuation marks, it loses much of its beauty and effectiveness. Without punctuation, writing can become difficult to follow, exhausting to read, and less impactful.
