Why your writing feels choppy: measuring cohesion and transitions

"It doesn't flow" is one of the most common notes writers get, and one of the least actionable. Flow sounds like a mystical property — something a piece either has or lacks. But most of what readers experience as flow is cohesion: the visible, countable connective tissue that tells a reader how each sentence relates to the one before it. And because it's countable, you can measure it, find where it's missing, and fix it sentence by sentence.

Linguists who study text cohesion — the classic account is Halliday and Hasan's 1976 work Cohesion in English — break it into a handful of mechanisms. Three of them are especially easy to check mechanically, and together they explain most "choppy" writing.

1. Transition words, by job

Transitions are the explicit signposts: however, therefore, for example, meanwhile. What matters isn't just how many you use but what jobs they do. Connectives sort into families — addition (furthermore, moreover, likewise), contrast (however, although, on the other hand), cause and effect (because, therefore, as a result), sequence (first, then, finally, meanwhile), and example (for instance, in particular, such as). A piece of argumentative writing that uses addition connectives but never contrast ones is usually a piece that never engages a counterargument; an explainer with no example connectives is often an explainer with no examples.

Density matters too. A useful rule of thumb is a few transitions per hundred words — enough that the reader is never left guessing how a sentence relates to its neighbor, not so many that every sentence begins with throat-clearing. The Text Cohesion & Transition Analyzer counts transitions across all five families, reports the density per 100 words, and shows the category breakdown, so you can see at a glance whether you're missing an entire family of connections.

2. Paragraph linkage

Sentence-to-sentence cohesion is only half the job. The other half happens at paragraph boundaries, which are exactly where readers fall out of a piece. A paragraph that opens cold — new topic, no backward reference — forces the reader to work out for themselves how it follows from what they just read. A paragraph that opens with a connective phrase ("On the other hand," "As a result," "For example") does that work for them.

Not every paragraph needs an explicit link; skilled writers often connect paragraphs by repeating a key term or continuing a thought instead. But if none of your paragraphs open with any linking language, the odds are good that at least some of those boundaries are abrupt. The analyzer checks the first sentence of each paragraph after the first for an opening connective and reports the linkage rate, flagging the specific paragraphs that start cold so you can judge each one on its merits.

3. Pronoun reference

The third mechanism is the quietest: reference. Words like it, they, this, and those are cohesive by nature, because they can only be understood by looking back at something already said. A sentence that begins "This is why the approach fails" is grammatically welded to the sentence before it. Writing with almost no pronouns tends to read as disconnected declarations — each sentence a fresh start, nothing carried forward. (The opposite failure exists too: pronouns whose referent is ambiguous. A counter can't catch that; only a careful read can.)

Abrupt shifts: where choppiness lives

Put the three mechanisms together and you can define the choppy sentence precisely: one that starts with no connective and no early referential pronoun — nothing at all tying it to what came before. One or two of these per passage is fine; openings and deliberate scene breaks should read that way. But when they cluster, that cluster is exactly the passage your beta reader would have circled. The analyzer lists these abrupt-shift sentences individually, which turns "it doesn't flow" into a to-do list: look at each flagged sentence and either add a signpost, swap in a pronoun reference, or decide the hard cut is intentional.

Reading the score honestly

The tool blends the three signals into a 0–100 cohesion score — weighting transition density most heavily, then paragraph linkage, then pronoun use. Treat the bands the way you'd treat any writing metric: a high score means the connective machinery is present, a low one means it's sparse. Neither is a verdict on quality. Cohesion is necessary for flow but not sufficient — a text can be perfectly stitched together and still be incoherent if the underlying ideas don't follow, and stuffing transitions into weak logic produces writing that's worse, not better, because the signposts promise connections the content doesn't deliver.

It's also worth knowing what a connective counter doesn't see: lexical cohesion, the repetition of key content words that carries a topic through a passage. That's a real and important mechanism — it's just a different measurement. If your score is low but your writing repeats its key terms faithfully, you may be more cohesive than the number suggests.

Run your next draft through it

Paste a draft into the cohesion analyzer and start with the abrupt-shift list rather than the headline score — it's the part that maps directly to edits. Then check the category breakdown for missing families of transitions, and the paragraph report for cold opens. If you want to go further on sentence-level texture, the sentence beginnings analyzer looks at the complementary problem: sentences that all start the same way. Between the two, "it doesn't flow" stops being a vibe and becomes a short list of specific sentences to fix.
