Eight Rules for Writing Sentences Readers Love — Ship30for30

Craft email (Apr 11, 2026) presenting eight concrete, objective sentence-level editing rules. All are mechanical and testable — you can point at a sentence and verify compliance. This makes them transferable to editors, checklists, or AI editing workflows.

Rule 1: End Strong

The last word of a sentence should be the most impactful word. “Do you know the name of who the president is?” ends on “is” — weak. Restructure so the heavy word lands at the end: “Do you know the name of the president?”

Rule 2: Define Your Acronyms

First use of any term: write it out fully, then parenthetical abbreviation. “Lifetime value (LTV).” After that, abbreviate freely. Every undefined acronym shrinks your audience to insiders only.

Rule 3: Say It in Fewer Words

Most first drafts are bloated. Edit in passes: write what you mean, hunt for removable small words, rearrange to stay grammatically correct. Example collapse: “Seven ways you can start to make more money your first year out of college by starting to write online” becomes “Seven ways to make money writing online as a new college graduate.” Same message, half the words.

Rule 4: Don’t Repeat Yourself

Writers constantly make a point then restate it in slightly different words. The reader gets bored because you are treading water instead of moving forward. The value of great writing is saying as many new things as possible, back to back.

Rule 5: Vary Your Word Choice

When repeating an idea, swap at least one key word. “Ice arena” twice in adjacent sentences feels clunky — change the second to “rink.” One word swap makes it immediately more readable.

Rule 6: One Advanced Word Per Sentence

Write at a fourth-grade baseline. Then add ONE challenging word for flavor. “He looked crazy” becomes “He looked preposterous.” One challenging word is a puzzle; ten challenging words are homework. Nobody wants homework.

Rule 7: The Two-Comma Rule

Most sentences should have two commas or fewer. Three to six commas is the valley of death — the sentence is rambling. Above six can work as an intentional stylistic choice for rhythm and pacing, but only if you know what you are doing.

Rule 8: Kill Your Adverbs

Adverbs usually repeat what you already said. “He ran quickly” vs. “He sprinted.” The second is cleaner and stronger. When in doubt, remove the adverb and find a more precise verb.

Takeaway for Sanity Check

These rules are objective and mechanical, which makes them ideal for a self-editing checklist or a CopyThat-style quality pass. Rules 1 (end strong), 3 (fewer words), and 8 (kill adverbs) are the highest-leverage for newsletter prose. The “two-comma rule” is a useful heuristic for catching run-on sentences during editing.
