Style Matters

WHY IT MATTERS  

A STYLE GUIDE is more than just a set of rules or an ornamental addition to a brand manual. It is a working document that helps an organization communicate clearly and consistently across all of its publications. For business schools, NGOs, startups, think tanks and other organizations focused on an international audience, that consistency is especially important because their communications often span teams, countries and formats. Although they may serve different functions, policy briefs, press releases, social media posts, annual reports, fundraising materials and/or websites should maintain a distinct style.

For many European organizations, this challenge is amplified by the realities of multilingual and international communications. English is often the language used for external publications, which increases the likelihood of inconsistencies when drafting or editing texts. A translator or AI agent might replicate source-language syntax, a specialist may provide terminology that has never been standardized, a commissioned agency could produce copy in British English, whereas an in-house copywriter might apply American spelling, vocabulary and punctuation standards. Taken together, these discrepancies can underwhelm first impressions.

This can be remedied with a reliable in-house style guide. It provides a consistent point of reference for writers, editors, translators, publications managers and communications teams while expediting production, minimizing uncertainties and safeguarding the organization's public image. Most importantly, it turns language from a secondary concern into a strategic asset.

WHAT TO INCLUDE   

A STYLE GUIDE supports clarity and consistency by documenting the organization's internal decisions about how texts should be written. Some guides, particularly in think tanks and academia, concentrate on the technical aspects of writing, including essential topics such as:


Abbreviations, acronyms and initialisms: Define first-use rules, whether periods are allowed (e.g., WTO / W.T.O.), when names are spelled out again, how abbreviation lists are handled and how articles such as “a” or “an” work before initials.


Capitalization: Set rules for sentence case vs. title case, job titles (Assistant Professor / assistant professor), departments, academic subjects, programs, official bodies and words following colons or in lists.


Citations, references and source notes: Define the house citation system, in-text citation style (e.g., author-date), bibliography / reference formatting, DOI/URL handling and footnotes vs. endnotes.


Dates and times: Specify date order, punctuation in dates, year spans (2020-2022 / 2020-22), decade style, time style and how date ranges should be written.


Headings, subheadings and title treatment: Specify how titles, subtitles, section heads, publication titles, as well as titles for reports, books, journals and programs should be formatted.


Numbers, numerals, percentages and ranges: Decide when numbers are spelled out (eight, nine, 10), when numerals are required (5 km), how percentages appear in text vs. tables, and how number ranges and large numbers are formatted.


Punctuation: Define house rules for comma style (serial / open), quotation marks, commas and periods with quotation marks, colons, semicolons, slashes, when to apply en dashes vs. em dashes and punctuation around footnotes.


Spelling standards: Choose a primary standard such as US or UK English, and specify preferred spellings and exceptions when the names of organizations use a variant.


Other guides, particularly for startups and social media companies, focus more on content-related matters:


     ● Audience, purpose and mission

     ● Brand, organizational and product naming

     ● Gender-inclusive and non-discriminatory language

     ● Social media and platform-specific writing

     ● Terminology and frequently used vocabulary

     ● Brand voice


A sidenote on artificial intelligence


As organizations begin incorporating AI into drafting and editing workflows, it is useful to have a style guide address the matter directly, because AI can introduce the same kinds of inconsistencies and reputational risks that were meant to be prevented in the first place. A guide that clearly explains how AI should be used can ensure that gains in efficiency do not come at the expense of accuracy, consistency or a coherent voice.


It may also be helpful to point out to employees or contractors that AI can be used as a support in writing but that it is not a substitute for editorial judgment. AI-assisted texts still need to be reviewed, which is why many organizations prefer to have that done by an in-house or contract editor before publication to make sure the final copy reflects the standards and voice that the style guide is meant to protect.

STYLE IN PRACTICE

If two media organizations were to produce nearly identical reports about the same event, their unique editorial style guides would lead to noticeable differences. Spelling, punctuation, capitalization, abbreviations, dates, numerals as well as preferred terminology all shape the final product, even if the underlying facts are identical.

A US media organization may write:


On July 9, 2024, at 3:00 p.m. EDT, Europe's new Ariane 6 rocket lifted off from the Guiana Space Center in Kourou, French Guiana, on its first test flight—a mission European Space Agency (ESA) Director General Josef Aschbacher called a "historic return" to independent access to space. The 56-meter launcher carried 11 small payloads—8 CubeSats, 2 reentry capsules and 1 experiment—and capped a 2020–24 development program reported to cost over €4 billion, or roughly $4.3 billion.


Whereas a UK organization might write:


At 9.00 pm CEST on 9 July 2024, Europe's new Ariane 6 rocket lifted off from the Guiana Space Centre in Kourou, French Guiana, on its maiden test flight a mission ESA director general Josef Aschbacher described as a 'historic return' to independent access to space. The 56-metre launcher carried eleven small payloads eight CubeSats, two re-entry capsules, and one experiment and concluded a 2020—2024 development programme put at more than EUR 4 billion, or about GBP 3.4 billion. 

Readers rarely pause to appreciate consistent capitalization, well-managed abbreviations or properly formatted dates. They do, however, notice when a publication feels uneven. A report that fluctuates between UK and US spelling, uses professional and colloquial language, or treats titles and acronyms inconsistently creates distraction and can undermine confidence in the material as well as the organization.


Standard reference works, though necessary, are only part of the solution. The Chicago Manual of Style, New Hart's Rules, Oxford Style Manual, APA, MLA and similar reference works provide established editorial standards, but they do not take an organization's audience, brand or publication requirements into consideration. A customized style guide addresses the gap by adapting a broad set of generic standards to an organization's specific needs.

WHERE TO START

A STYLE GUIDE is one of the most efficient ways for an organization to improve the quality and consistency of its communications. It creates a common standard, assists internal teams and external contributors, and it ensures that publications represent the organization's level of professionalism. It is especially important for multinational organizations to provide publication guidance in an environment where numerous English standards, writers and audiences intersect.

Organizations do not need a style guide because language must be monitored. They need one because using clear, consistent language saves time, avoids inconsistencies and maintains the confidence of the target audience. A well-designed guide collates dozens of editorial decisions that might otherwise be made without a common standard, thereby ensuring that the organization's voice is not left to chance.

With that in mind, it is important to consider the benefits of hiring a professional copyeditor or proofreader to assist with the development of a style guide. An experienced editor can condense varied editorial conventions into a tailored manual, ensuring that language quality is built into the process and not just applied in the final stages. A style guide is more than just a set of rules – it is a practical investment in an organization's future.
