Nib #143 Back to Basics: The Comma Splice

“No comma splices” is one of those ubiquitous writing tips everyone has heard… but most young writers today don’t understand. (“It’s not your fault, Will. It’s the education system’s.”)

So, what is a comma splice? It’s the grammatical mistake of trying to link two independent clauses with just a comma and no helping word. Like this:


Rover was a beagle, he was a good boy.


Both independent clauses here are fine. The problem is linking them with just a comma. There are lots of correct ways you could present these clauses. 


If you’re sure you want to connect them in the same compound sentence without a linking word, you need a semicolon, not a comma (IC; IC):


 Rover was a beagle; he was a good boy.


If you wanted that extra beat of a short linking word, you could keep the comma and add a coordinating conjunction (IC, cc IC):


Rover was a beagle, and he was a good boy.


Or you could, Hemingway-style, just make them two simple sentences:


Rover was a beagle. He was a good boy.


But the one thing you can’t do is splice two independent clauses together with a comma. Now you know.

In honor of the great Tom Skerritt, who died last week at 93, this week’s (appropriately brief) Nib celebrates the Nibbiest scene in the history of movies: the “Half As Long” scene from A River Runs Through It.

Dangling participles are one of those grammatical faux pas — like comma splices ( Nib #143 ) and the passive voice ( Nib #106 ) — that young writers today have probably heard of, but were never really taught. (Once again, Will, it’s not your fault.)

One of the weaknesses of American public discourse these days is that persuasive writers ignore Thomas Sowell's famous observation that, “There are no solutions. There are only trade-offs.” Whether it’s a campaign speech, a sports radio rant, or a policy op-ed, arguments these days tend to be presented as if they are pure upside, win-wins for everyone (or at least everyone who matters). Writing like this, especially in our low-trust culture, is the opposite of persuasive. It’s off-putting and exclusionary. Ignoring contrary opinions does not make them disappear — it makes you boring. By acknowledging the trade-offs attendant to your ideas — banning the Electoral College, firing Dan Quinn, whatever — you get to frame the trade-offs. You can present them in the best light, strengthening your own argument by contrasting it with alternatives. If your argument can’t withstand your own cost-benefit analysis, it’s unlikely to persuade undecided readers, either. Until next week… keep writing!

There’s no right way to start a sentence. But there are some wrong ways. One of those is labeling — wheel-spinning introductory phrases like: “In terms of…” “As it relates to…” “With respect to…” Seen in isolation, they don’t seem so bad. But in practice, they’re clunky and unnecessary: “In terms of awards, Tom Cruise has never won a competitive Oscar.” “As it relates to national security, China remains America’s greatest rival.” “With respect to holidays, I prefer Christmas to Thanksgiving.” Look how much cleaner those sentences become without the labels: “Tom Cruise has never won a competitive Oscar.” “China remains America’s greatest national security rival.” “I prefer Christmas to Thanksgiving.” “Omit needless words” is one of the most fundamental bits of writing advice there is. And sentence-opening labels are about as needless as words get. Until next week… keep writing!

College application season is once again at our throats, and with it, the universal adolescent dread of the Personal Statement. There’s lots of good technical advice about how to do these high-stakes 650-word essays — what to write and what not to write (including Nib #23). But the real secret is not technical; it’s strategic: Don’t use your Personal Statement to try to impress other people. Use it to reveal yourself. Don’t try to write an autobiography in 650 words. You won’t succeed, and 17-year olds don’t have that much to write about anyway. Moreover, don’t rehash “accomplishments” already listed elsewhere on your application. They’re unlikely to be much different from everyone else’s. Instead, write in such a way that readers will know you a little bit. Write about a failure, a dream dashed, a relationship, or a moment — big or small — that taught you some lesson. Think about how you really get to know someone. It’s not their resumé, it’s their spirit, the Truth behind the facts. Write “authentic” — especially when most of your peers will use AI — and “impressive” will take care of itself.

One of the most common questions the Nib gets from young writers is, “What do I do when superiors in my office suggest changes to my drafts that I disagree with?” The answer is very simple: make the changes. But what if they throw off the rhythm? What if they undermine a delicately crafted metaphor? What if they add three sentences and that means 50 words have to be cut somewhere else? Again: make the changes. There are several reasons why. First, they’re your bosses. Do what you’re told. Second, 99% of what we write does not matter — so neither do 99% of suggested edits. Third, and most important, the more obligingly you take people’s edits, the fewer you’ll get. Resist edits, and you’ll get a reputation as a prima donna, whose writing therefore deserves extra scrutiny. Take your superiors’ suggestions, and over time they will trust your writing enough not to nitpick it. Once your reputation is established, you’ll even earn the standing to occasionally push back. Taking edits is good for your soul and your career. Until next week… keep writing!

Rule #13 in Strunk & White still holds: “Make the paragraph the unit of composition.”  Don’t think of your writing as a collection of words or even sentences, but paragraphs. Each paragraph should present One Complete Thought — one idea, one step in the story you’re telling or the argument you’re making. Paragraphs signal all this simply by how they look. The line break and indentation tell the reader, We’re done with the previous idea and moving on to a new one. Take advantage of those visual cues as you draft and revise your work. Open paragraphs with some kind of topic sentence to tee up what follows. Close them with a good kicker that polishes off the point or springboards readers into the next paragraph. You can even outline your piece this way — plan one paragraph for each main point in your outline. Readers read in paragraphs, so writers should write in paragraphs too.

When writing first drafts, writers are usually still working out what we think. One result is duplicate sentences. We unconsciously state the same thought in different ways, often back to back. Just like the two previous sentences! Or consider these examples: This bill will only raise taxes on people making more than $1 million per year. It won’t raise taxes on anyone making less than seven figures. The hotel was farther from the city than we expected. We were surprised by how long it took to get downtown. This kind of repetition is natural in conversation. But good writing doesn’t ask readers to pay for the same real estate twice. When editing your writing, be on the lookout for twin sentences. Pick the one that sounds best, or take the best from each to form a better one, and delete the rest. Until next week… keep writing!

The hardest part of writing about public policy is making substantive arguments without getting lost in the weeds. Disagreements over policy minutiae in a speech or op-ed have reduced more than one congressional office to a Hobbesian state of nature. So here are two tips for finding the right balance between wonkiness and accessibility. Tip #1 : Ask yourself who your audience is. If they are experts, then write wonky. If they’re laymen, make the language more accessible. If the answer is somewhere in between, Tip #2 is that when you have to write for both, write to both. Think of your audience as two particular people: Dr. X, a world-renowned expert on your topic, and Mrs. Y, a smart, educated, and curious layman. Set your tone, choose your words and emphases, and present your argument and evidence in such a way that it won’t bore Dr. X or bewilder Mrs. Y. Provide enough context so non-experts can follow along, but not so much that experts will feel their intelligence insulted. If you can connect with both Dr. X and Mrs. Y, you’ll connect with everyone in between them too. Until next week… keep writing!

One of the most powerful writing tips anyone can learn is to never just write . Always write to an audience . Before you write word one, before you even outline your composition, clarify in your mind, as specifically as you can, who your reader is. Is it your teacher? Your boss, coworker, or subordinate? A friend, sibling, or parent? A romantic prospect? A business, nonprofit, or government agency? If your audience is a group of people, what kind of people? Are they religious? Educated? Wealthy or poor? Idealistic or cynical? Young or old? Male or female? Conservative or progressive? Knowledgeable or unfamiliar with the topic? If you were talking with these people, you would adjust your tone, word choice, and sentence structure based on who they are. Do the same with your writing. If you want to connect with your audience, you have to know who they are and how they think. Take the time to figure that out before you start writing. It will make your drafting smoother and your drafts better, guaranteed. Until next week… keep writing!
