How do I write instructions for readers who may not know the same terms I do?

Start with terms that affect what readers do, see, or decide—not every specialized word in the draft. Read each instruction as if you had never used the process. Ask: Could I follow this step without knowing this word? Could two readers picture different things? Could someone mistake it for another part or action? Flag terms where the answer is yes, especially names for controls, materials, settings, or steps. You do not need to remove every technical term; you do need to make essential ones understandable.

Use a short definition when readers need to understand a term before acting, or when the step does not make its meaning clear. Use a label in context when the surrounding action or wording makes the meaning evident. For example, in a hypothetical instruction, “Turn the selector to ‘Eco’” may identify the control’s label if “Eco” is printed on it. If readers need to know what the setting means in order to choose it, explain that meaning in plain language.

Consider a visual when readers need to locate a part, distinguish similar-looking items, or understand a position that is hard to describe briefly. Pair it with a clear text label, and make sure the illustration actually identifies the feature. A picture should support the step, not leave readers to guess which part matters. If you cannot confidently explain a term or verify a visual label, mark it for confirmation rather than guessing.

Use one row for each term that could affect understanding. Here is a copyable layout:

Term in draft | Where it appears | What the reader needs to know | Treatment | Preferred wording | Visual or label needed? [term] | [step or section] | [plain-language meaning or distinction] | [define / label in context / visual] | [consistent term] | [yes/no; describe]

For a made-up example, suppose a draft calls the same part “release catch” in one step and “latch” later. If those names refer to the same part, choose one reader-facing label and use it throughout the instructions and visuals. Define it at first use if needed. If they refer to different parts, keep both names and clarify the distinction.

For each row, search the whole instruction set for other names for the same thing. Check headings, captions, diagrams, warnings, and step text—not just the first paragraph. If a familiar everyday name helps readers, you can pair it with the chosen term once, then stick to the chosen term. Avoid introducing an unexplained synonym later just to vary the wording.

Ask someone who has not followed your drafting process to read a few representative steps and explain what they would do or look for. Treat confusion as a signal to revise the wording, context, or visual—not as a reason to add more jargon. If you cannot get a new reader’s perspective, note that in your review. Your familiarity with the material can make unclear terms seem obvious.

For a final check, confirm that each essential unfamiliar term is explained, made clear by context, or supported by an appropriately labeled visual. Make sure the preferred name stays consistent wherever the same thing appears, and that each visual matches the text. Keep the table with your draft so future edits have a reference. If a term’s meaning or correct label is uncertain, use a placeholder such as [confirm part name] and resolve it with someone who can verify the intended wording before publishing.
