TK and why it’s helpful when writing fiction or non-fiction in English

From Print Shops to Newsrooms

The origins of TK reach back to the age of print. In printing shops and newsrooms, compositors once jotted tk, pronounced “to kum,” in the margins to mark missing material [3]. (The playful mispronunciation was a kind of typesetter’s in-joke: “kum” winkingly alluded to the missing “co” that would complete to come [3].) A Chicago Style Q&A explains that tk was a printer’s expression meaning “material is to come.” Editors appreciated that it was “tk” rather than “tc,” a little secret code scribbled only by the initiated [4].

By the late 20th century, journalists picked up the habit. New York Times language columnist William Safire even wrote about “Of Hacks and TK,” noting that columnists and copy editors used TK to flag unfinished paragraphs. TK’s utility spread as computers gave writers more flexibility: insert TK as a placeholder, then fill it in after the creative impetus has moved on.

Why “TK”?

Few letter pairs in English are as unusual. Using TK instead of the obvious TC (for to come) isn’t an accident: it’s exactly why the trick works. As Literary Hub editor Sophie Vershbow recounts, “TK… is a unique and visually arresting letter combination” [5]. In digital drafts it’s even searchable: a quick Ctrl+F hunt will snag every TK far faster than chasing down every “to.” Software like Medium now highlights TK for you. Writer Barb Dalton noticed that when she typed TK in a Medium draft, “a little yellow TK appeared” by the margin – a gentle nudge before submission [6]. In short, TK is a lighthouse for missing text. It won’t slip into your final prose unnoticed.

TK Keeps Creativity Flowing

The real magic of TK is psychological. Writers hate breaking their train of thought to verify a detail. A sudden internet search for a fact can derail momentum and provoke a blank-page panic. That’s why TK has become “one of the most beautiful tools a writer can add to their arsenal” [1]. By stamping TK in place of, say, a yet-to-be-determined ship name or historical date, a writer tells the inner editor: “Don’t stall me here.” This placebo leapfrog keeps the pen—and the mind—moving forward [1] [7].

Reaching The End of a draft often requires ignoring imperfections. Writing coach Natasha Khullar Relph notes that “English-language journalists often use the ‘TK’ placeholder to maintain their writing flow and avoid getting stuck” [7]. Once the draft is down on paper, the author can return and systematically fill in all the TKs. In fact, the technique creates its own kind of consistency: as one fiction writer explained on Reddit, using TK for everything unsettled allows “ranks, planet names, how guns work, etc.” to be ironed out later in one go [8]. It’s a sort of controlled suspension of disbelief, freeing writers from trivia until the big picture is done.

The Three Key Benefits

Move Faster: Writers report they “move faster” by plugging TK placeholders instead of pausing on a detail [8]. No more stalling over character surnames or side facts.

Stay in the Flow: Each TK is a breadcrumb to revisit. You keep the creative juices flowing and lock down consistency after the main draft is complete [7] [8].

Catch Everything: Because TK is so rare in prose, every instance jumps out. You won’t overlook a needed insertion if you tabulate or search for TK later [2] [5].

This method appeals both to disciplined journalists and to carefree novelists. On forums and in blogs, writers from across genres praise TK. As a U.S. Air Force officer writing a sci-fi novel noted, the technique gave him the “consistency” of sorting out details only after getting the story down [8]. In corporate and tech writing, people who’ve never worked on a newspaper still find it “the most useful shorthand” they have [9]. On the other hand, people unaware of publishing lingo can be perplexed. Vershbow recounts how colleagues in a tech job often asked “what does TK mean?” once they saw it flagged.

From Linotype to Laptop: TK’s Modern Life

Today’s writers use TK exactly as the printing trade intended – and more. Literary novelist Paul Glynn joked that “TK” might as well stand for “Truly Kooky,” but admitted he used it liberally in early drafts. Medium and Google Docs simply take the hint and throw up a reminder. In practice, common usages of TK include: names of people or places, precise figures (years, statistics, prices), historical or technical facts, or even section headings. For example: “The din of conversation grew [TK – West Wing? East Wing?] as the meeting continued.” or “She surveyed the [TK – highest bidder] on the auction floor.” Writers in a hurry fill the brackets or capital TK where needed and barrel on [10] [1].

Tips for Using TK in Your Writing

Thanks to this checklist mentality, writers report steeper productivity. In one writer’s experience, embracing TK turned a tortuous 300-word hour pace into a brisk sprint. The placeholders gave “two reasons” for improvement: faster pace and consistent revision management [11]. Such testimony and guides echo an established piece of writing lore: don’t let perfectionism stall progress. TK is a safety valve against the writer’s paralysis of thought.

The Dark Side: Critiques of TK

No hack is without its skeptics. The Chicago Manual of Style (CMOS) warns that TK is imprecise. A CMOS Q&A bluntly recalls TK’s printerly origins but counsels authors to be “more straightforward and specific” in final manuscripts [12]. Chicago suggests alternatives – e.g. using placeholder bullets or explicit comments (HTML comments, etc.) – especially if the document goes through multiple drafts and authors. Some editors cringe at seeing “TK” on pages, fearing it might slip into print or confuse collaborators. In early-2000s newspaper etiquette, leaked memos even forbade using TK in article drafts. The argument goes: perhaps spelling out “figure here” or “stat to add” is clearer to anyone who inherits the text.

Yet for many working writers, that caution is a small price. They reserve TK for drafts only, relying on edit passes to clean house. Copyediting guru Benjamin Dreyer quipped that the exercise of hunting TK before publishing is part of routine copyedits. Even Vershbow notes that despite its oddity, she clings to TK as a vestige of her publishing background: it “holds onto a piece of myself I’m not fully ready to let go of.” [13] In other words, for some writers it’s as much a psychological comfort as it is a practical tool.

A balanced approach is best: know your audience. If you’re handing a draft to a traditionalist editor, a brief explanation (“I’ve used TK as placeholders here”) can pre-empt confusion. If you’re a lone novelist, use all caps or brackets so nothing slips into the final version. Above all, remember that TK is meant to be temporary. Its value lies in marking unwritten text – the goal is to make sure it gets written before the story sees the light.

Ultimately, “TK” endures because it solves a real problem of craft: how to keep creativity unbroken by the mind’s urge to over-edit. It’s a permission slip for first drafts, a way of promising yourself you will fill in the blanks later. Like leaving a sticky note on a desk, it turns a hitch in thought into a post-it waiting to be addressed. When used wisely, TK is indeed “one of the most beautiful tools a writer can add to their arsenal” [1].

Modern writing is as much about speed and iteration as it is about elegance. A placeholder like TK acknowledges that the writing process is messy. It gives permission to scribble down the story and worry about the footnote afterwards. Novelist and writing coach advice often condenses to: “Get the words out, then shape them.” In practice, TK helps make that principle possible.

So the next time you find yourself staring at a gnarly paragraph, longing for the perfect phrasing or data point, remember the humble TK. Let it stand in for your missing link, your buried name, your statistic to come. It’s the phantom aide of editors and authors alike – unseen by readers, but essential to writers. And when the novel is submitted or the article in copyediting, every lonely TK will have become a real word, fact, or name, hidden no more [7].
