Good writing is less a talent than a series of decisions made in the reader's favor. Before drafting, you decide who will read the piece and what it must do for them. While drafting, you decide what to claim, how to support it, and what order will carry the reader from one point to the next. Afterward you revise the structure, edit the sentences, and check the details a reader trips over. The chapters follow that sequence, then turn to the common genres and to using sources honestly.
Each chapter opens with the short version. Tap one to read the detail.
Start from the reader and the situation
~2 min
Who is reading, what they already know, and what you need them to do decide almost everything else: how much background to give, which terms to define, what tone to take, and what to put first.
Readers arrive with different backgrounds and different questions. A manual for experts can skip definitions that would stop a newcomer cold, and a summary for an executive leads with the decision and its cost rather than the method. Before drafting, picture the actual reader: what they know, what they want from the document, and what would make them stop reading.
Purpose comes next. A piece written to inform succeeds when it is clear; one written to persuade succeeds when it changes a mind or prompts an action. Writers who never settle the purpose produce drafts that drift, explaining for a paragraph and arguing in the next.
Classical rhetoric named three ways a text persuades: through the writer's character, the reader's feelings, and the argument itself. On the page, character shows in accuracy and fairness, feeling comes from concrete detail rather than adjectives, and argument shows when each step can be checked.
Voice and register follow from the situation. A friendly, direct voice suits most documentation, and a formal register suits a legal notice. The common mistake is switching between them, sounding chatty in one paragraph and stiff in the next. The same reader focus extends to layout: people reading on screens scan, so headings, short paragraphs, and lists are part of writing for them.
Rule: before the first sentence, be able to say who the reader is, what they need, and what you want them to do afterward.
Plan before you draft
~2 min
Most drafting trouble starts earlier: a topic too broad to cover, evidence gathered after the outline was fixed, or notes that lost track of their sources. Narrow first, research with a rough outline, and record every source as you go.
A broad subject cannot be covered well in a short document. Narrowing it to a specific question, place, period, or audience is what makes depth possible: "renewable energy" becomes "whether the district should put solar panels on its three high schools." Brainstorm freely at this stage and judge later, because criticizing ideas as they appear leaves too few to choose from.
Start with a rough outline, then research, then revise the outline to fit what you found. Evidence changes which points matter and in what order, and an outline fixed too early tempts writers to ignore good material or to stretch weak points to fill planned sections.
Take notes so that attribution survives into the draft. Record the source and page with every fact, and mark which notes are exact quotations and which are paraphrases. Losing that information costs hours of searching later, or produces plagiarism nobody intended.
When material comes from several sources, synthesize rather than summarize: organize by idea and show where the sources agree, where they conflict, and what is still unknown. When a team writes together, agree early on the outline, the schedule, and a shared style sheet, and plan a final pass by one editor so the result reads as one document.
Rule: narrow the topic until you could defend it in depth, and never write down a fact without its source.
Claim, support, and the order that carries them
~2 min
A strong piece makes one arguable claim, supports it with evidence the reader can check, ties each piece of evidence to the claim explicitly, and deals fairly with the best objection. Structure puts each of these where readers expect to find it.
A thesis is a claim a reasonable reader could dispute. "The library opened in 1962" is a fact to verify; "the library should open on Sundays because weekday hours exclude working families" is a claim that needs support. If no one could disagree, there is nothing to argue.
Support has three parts: the claim, the evidence, and the reasoning that links them. The link is where arguments usually fail. A rise in visits after a new policy does not show the policy caused it until other causes are ruled out, so state the connection outright instead of leaving readers to supply one.
Answer the strongest objection, not the weakest, and describe it in terms its supporters would accept. A fair concession, such as granting that Sunday hours cost more and then showing why the cost is worth it, makes the rest of the case more credible. Fit each claim to its evidence: "in these three branches" survives a counterexample that "everywhere" does not.
Order matters. Readers give the most attention to the beginning and the end, so the strongest points belong there. In most documents, state the main claim early, introduce each section with its purpose, and end with what follows from the argument or what the reader should do next, rather than repeating the introduction.
Rule: if you cannot say why your evidence proves your claim, the reader cannot either, so write the link down.
One idea per paragraph, linked to the next
~2 min
A paragraph develops one idea, announced near its start. Readers can follow a run of paragraphs when each sentence grows out of the one before and the transitions name the real relationship between ideas.
Treat the paragraph as a unit: one main idea, stated near the beginning and developed with examples, details, comparisons, or causes. When a paragraph turns to a second topic, start a new one. Skimmers read first sentences, so a topic sentence that says what the paragraph shows serves them directly.
Within a paragraph, sentences hold together when each starts from something the reader already has. "The council approved the levy. The levy pays for two new buses, and the buses will serve the east side" moves smoothly, because each sentence picks up where the last left off. Repeating a key term helps here; swapping in synonyms for variety makes readers wonder whether you mean something new.
Between paragraphs, a transition names the relationship: addition, contrast, cause, sequence, or example. Choose the word that matches the logic. "In addition" in front of a cause misleads the reader, and a "Moreover" at the head of every paragraph signals connections the text never makes.
Comparisons can run subject by subject or point by point; the second suits detailed comparisons, where readers need both items side by side on each criterion. Lists help with parallel, separable items, as long as every item takes the same grammatical form.
Rule: put each paragraph's point in its first sentence, then check that every sentence after it starts from something the reader already knows.
Sentences readers can take in on one pass
~2 min
Put the actor in the subject and the action in the verb, keep the subject near its verb, end on the point you want stressed, and cut words that carry nothing. Most advice about style is a version of these four moves.
A sentence reads most easily when its subject names who acts and its verb names the action. "A review of the contract was conducted by the legal team" hides both; "The legal team reviewed the contract" shows them. Hidden verbs, nouns built from verbs such as "review" or "decision," often signal a sentence that can be rebuilt around its action.
The passive voice is a tool, not an error. It fits when the actor is unknown or unimportant, as in "The records were damaged in the flood," but not when it serves to avoid saying who is responsible.
Keep the subject close to its verb. When a long clause separates them, readers must hold the subject in memory until the verb arrives. Use the end of a sentence for emphasis, since readers expect the new or important element there, and vary sentence length so a short sentence can land a key point.
Concision means cutting words that add nothing: "due to the fact that" is "because," and "very important" is weaker than "essential." It does not mean cutting a qualification or example the reader needs. A specific detail, such as "the bus was late eleven times in March," does more than a general claim that service was unreliable.
Rule: find the actor and the action in every heavy sentence, make them the subject and the verb, and let the end of the sentence carry the point.
Plain words, chosen precisely
~2 min
Plain language means readers can find, understand, and use your text the first time they read it. That takes familiar words, defined terms, one name for each thing, and a steady tone, not a smaller vocabulary.
Plain language is not simplified content; it is content written for the actual reader. In practice that means familiar words ("use," not "utilize"), concrete terms instead of abstractions such as "factors" and "issues," and a definition for any specialized term the first time it appears. Spell out an abbreviation at first use, and skip the abbreviation entirely if it appears only once or twice.
Precision means the right word, not a nearby one. "Fewer" counts things and "less" measures amounts; "continual" means repeated and "continuous" means unbroken. Loaded words such as "scheme" for a plan, euphemisms that hide a fact, and buzzwords such as "leverage" all cost the reader clarity.
Address readers directly as "you," and write instructions as commands: "Save the file. Close the window." Keep sentences to a manageable length with one main idea each, and treat readability scores as a warning, not a target.
Tone should stay steady. A document written by several people often swings between casual and formal, which distracts readers, so a final pass should bring the parts into one voice. Humor rarely survives translation, and exclamation points rarely help.
Rule: when a plainer word says the same thing, use it; when a more precise word says more, use that instead.
Revise the structure, then edit the sentences
~2 min
Revision rethinks content and organization, editing polishes sentences, and proofreading catches errors. Doing them in that order, in separate passes, saves the time you would otherwise spend polishing paragraphs you later cut.
Revising and editing are different jobs. Revision asks whether the document holds the right information at the right level for its reader, in a sensible order, with topic sentences and transitions that show the structure. Editing improves sentences and word choice, and proofreading looks for errors. Polishing prose before the structure is settled wastes effort, since a structural fix may delete the polished paragraph.
Work in passes, each with a single focus: content and organization first, then style, then consistency and correctness. Cut material that does not serve the reader, even when it is accurate, and move it to an appendix if it is too valuable to lose.
Feedback helps most when it addresses the writer's purpose and reader rather than the reviewer's taste. When you receive it, sort the comments into those that are critical, those that would be nice to address, and those you can set aside.
For the final check, read aloud, which catches missing words and sentences that break their own pattern, and do not trust a spellchecker with real words used wrongly, such as "form" for "from." Confirm that every link and cross-reference works, that terms and formatting stay consistent, and that the document looks right in the form the reader will see.
Rule: never proofread a draft you have not yet revised.
Each genre is a promise about form
~2 min
Genres exist because readers know what to expect from them: an executive summary gives the decision first, a memo states its purpose up front, a review names its criteria. Keeping the promise lets readers find what they need.
The classic modes of discourse still describe what most writing does: exposition explains, description makes the reader see, narration tells what happened, and argument persuades. Most documents mix them, but each passage should know which one it is doing. An explanation that starts taking sides has become an argument and must meet that standard.
Workplace genres add a fixed form. A memo opens with its purpose and ends with any action required. An email puts its request near the top and asks for one thing. A proposal states the problem, the solution, the cost, and why the writer can deliver. Instructions list prerequisites, then numbered steps with one action each, and place each warning before the step it concerns.
Reports and reviews carry their own obligations. A research report keeps results separate from their interpretation. An executive summary stands alone for readers who will read nothing else. A review states its criteria and judges the subject against each one with evidence, which lets readers who weigh the criteria differently reach their own conclusion.
Writing for screens means putting the answer first, using descriptive headings, and keeping paragraphs short, because people reading online scan.
Rule: before drafting, name the genre and list what its readers will look for first, then put that first.
Use sources honestly and visibly
~2 min
Research starts with a question narrow enough to answer, continues with sources you have evaluated, and ends with every borrowed idea and phrase credited where it appears. Most plagiarism comes from careless notes, not intent.
A good research question is narrow enough to answer with the sources available. Search with keywords and Boolean operators, then evaluate what you find: who wrote it and with what expertise, whether its claims are supported, whether it is current, and whether its publisher has a stake in the issue. Scholarly and primary sources carry more weight than popular summaries.
For each borrowed idea, decide whether to quote, paraphrase, or summarize. Quote when the exact wording matters, and copy it exactly. Paraphrase in your own words and sentence structure, not by swapping synonyms into the original sentence, which still passes off someone else's phrasing as yours. Summarize when only the main point is needed. All three need a citation.
Introduce borrowed material with a signal phrase that names its source, such as "According to the county's 2023 audit," and cite it where it appears. Join quotations to your own sentences grammatically, mark omissions with an ellipsis and insertions with square brackets, and never use either to change the meaning.
Plagiarism covers unquoted copying, uncredited ideas or data, and this kind of synonym-swapping. Images, charts, and tables need credit too, and often permission.
Rule: if a reader could not tell which words and ideas are yours, add the quotation marks, signal phrase, or citation that would tell them.
