When to Include, Exclude, or Occlude Words for Clear Writing

Clear writing hinges on deliberate word choice. Deciding when to keep, cut, or camouflage a word shapes how quickly readers grasp your message.

Mastering these three moves—include, exclude, occlude—prevents cognitive overload and builds trust. Below, you’ll learn exactly when to apply each tactic, why it works, and how to spot opportunities in your own drafts.

The Cognitive Cost of Every Word

Working memory holds roughly four novel chunks at once. Each extra adjective or qualifier competes for one of those slots.

Readers pay in effort what writers save in brevity. The more tokens you feed the sentence, the slower comprehension becomes.

Neuroimaging studies show jargon spikes activity in the prefrontal cortex, the same region taxed by multi-step math. Plain language keeps the load in the temporal lobe where pattern recognition is faster.

Include: Signal Words That Anchor Meaning

Concrete Nouns Beat Abstractions

Swap “asset” for “1972 Fender Stratocaster” and the brain visualizes instantly.

Concrete nouns trigger sensory cortex activation, giving readers a free picture.

When precision matters—safety instructions, legal duties, medical dosages—always choose the tangible term.

Verbs That Show Motion

“Slams” outranks “exerts force” on both EEG emotion gauges and eye-tracking heat maps.

Motion verbs simulate mirror-neuron responses, letting readers feel the action.

Use them to open blog posts or product narratives; they glue skimmers to the line.

Transitional Glue Words

“Yet,” “because,” and “after” compress logical relations into single syllables.

They slash rereading by 23 % in usability tests because they broadcast pivot points.

Insert them whenever a paragraph changes causal direction.

Exclude: Ruthless Pruning for Velocity

Adjective-Adverb Clusters

“Extremely very large” adds zero bytes of new information.

Keep the strongest modifier; delete the rest.

Your sentence retains color without syrup.

Throat-Clearing Phrases

“It is important to note that” burns five words before the payload.

Cut straight to the clause that follows; importance is implied by position.

Scan your draft for “there is,” “it should be noted,” and similar filler—then strike.

Redundant Pairs

“Each and every” or “null and void” arose in legal English to cover etymological doubts.

Modern readers need one term.

Pick the variant your audience knows best.

Occlude: Strategic Hiding for Clarity

Parenthetical Minimization

Non-essential dates or citations can tuck into brackets or footnotes.

The main clause stays lean while optional data remains reachable.

Academic bloggers who moved disclaimers to sidebars saw on-page time rise 18 %.

Ellipsis for Predictable Lists

“Apples, pears, oranges …” signals continuation without enumerating twenty fruits.

Readers pattern-match and skip, saving mental bandwidth.

Use when the full set is understood or searchable elsewhere.

Progressive Disclosure in UI Copy

“Learn more” links collapse advanced settings until the user exhibits curiosity.

Surface-level prose stays uncluttered, reducing bounce rates.

Heat-map studies confirm 34 % fewer fixations on hidden details until expansion is clicked.

Diagnostic Tools to Spot Overload

Microsoft Word’s Editor now flags glue-index scores above 0.4, a proxy for excessive function words.

Paste your text; aim for a 0.25–0.35 band.

Google Docs’ word-frequency add-on highlights repeats—anything above 2 % density is a candidate for synonymy or deletion.

Audience-Specific Thresholds

Expert Audiences Tolerate Density

Radiologists expect “pleural-based mass”; “lump on lung lining” slows them down.

Keep the term, but embed a parenthetical definition on first use for mixed readerships.

This hybrid approach satisfies both speed and accessibility.

Novice Audiences Need Air

New investors stop at “EBITDA margin.”

Replace with “operating cash profit as a percentage of sales,” then reintroduce the acronym two paragraphs later.

Spacing the jargon gives memory time to consolidate.

Syntax Tricks That Trim Fat

Appositives compress biography: “Lisa, a nurse from Lagos, …” removes the need for a second sentence.

Em-dashes create micro-occlusions—insert side notes without commas that breed confusion.

Periodic sentences flip clause order to stash long conditions at the end, keeping the main payload upfront.

Rhythm and Pace: Short Bursts vs. Long Rolls

Monosyllabic clusters (“Build. Test. Ship.”) hammer urgency in launch emails.

Alternate with longer explanatory sentences to avoid fatigue; contrast sustains attention.

Read drafts aloud; switch tactics where your tongue stumbles—that’s the reader’s tripwire too.

Case Study: 53 % Fewer Support Tickets

A SaaS startup rewrote its onboarding wizard, cutting 1,200 words to 600 and occluding advanced settings behind toggles.

First-week support tickets dropped from 412 to 193 because users located core actions faster.

Retention climbed 9 % the following month, tracing directly to reduced cognitive friction.

Checklist for Final Pass

Highlight every adverb; justify each with a metric or delete.

Search “that”; if the sentence works without it, yank.

Count sentences longer than 26 words; split or occlude sub-clauses until below the threshold.
