The language industry loves abbreviations. G11n, i18n, l10n and t9n appear in job titles, software documentation and conference talks, and they are frequently muddled. The confusion is more than cosmetic: these terms describe genuinely different activities performed by different people at different stages, and conflating them causes expensive planning mistakes.

Globalisation (g11n): the business ambition

Globalisation is the broadest term. It describes everything an organisation does to operate internationally: market strategy, distribution, legal structures, pricing, hiring, and of course communication and product adaptation. In the language context, globalisation is the umbrella under which the other activities sit.

A globalisation strategy answers questions such as which markets to enter first, how offerings should differ between regions, and how centrally local activity should be managed. It is driven by business leadership rather than engineers or translators.

Internationalisation (i18n): designing for the world

Internationalisation happens at the design and engineering stage. It means building a product, application or content system so that it can later be adapted to multiple languages and regions without engineering changes. The abbreviation comes from the eighteen letters between the "i" and the "n".

Typical internationalisation work includes:

  • separating all user-facing text from code, so strings live in external resource files;
  • supporting non-Latin scripts, right-to-left layouts and varying text lengths, because German words are longer than English words and interfaces must not break;
  • designing flexible date, time, number, currency and address formats rather than hard-coding one country's conventions;
  • avoiding embedded assumptions about names, telephone numbers, units of measurement or colour symbolism;
  • ensuring systems handle Unicode and multiple languages simultaneously.

Internationalisation is invisible when done well and painful when done badly. A product that was not internationalised may need substantial re-engineering before a single word can be translated.

Localisation (l10n): adapting to a market

Localisation is the process of actually adapting a product or content for a specific target market. Translation is a central part of localisation, but only one part. Full localisation often addresses:

  • translation of interfaces, help systems, documentation, marketing and legal content;
  • region-specific formats for dates, units, currencies and addresses;
  • regulatory compliance, local payment methods and customer-service expectations;
  • imagery, examples, colours and symbols that may carry different meanings;
  • cultural adaptation of tone, humour, idiom and references.

The distinction matters because a word-perfect translation can still fail locally. An interface translated into Arabic but laid out left-to-right, a European product showing prices in the wrong format, or marketing imagery considered inappropriate in the target culture all demonstrate the gap between translation and localisation.

Translation (t9n): meaning across languages

Translation is the specific linguistic activity: taking written content in a source language and producing equivalent written content in a target language, preserving meaning, register and purpose. Within localisation projects, translation may be performed by in-house teams, agencies or freelance specialists, supported by translation memories, termbases and, increasingly, machine output with professional review.

Where transcreation fits

One term closely related to localisation deserves its own mention: transcreation. Used mainly for marketing and advertising, transcreation begins from the desired effect rather than the source words. A slogan, campaign concept or brand message that works brilliantly in one market may fall flat, confuse or even cause offence elsewhere, and literal translation rarely rescues it. Transcreators therefore often produce several adapted options, explained back to the client with reasoning about how each will land.

The process blurs the line between translation and copywriting, which reflects a deeper truth: the more emotion and persuasion a text contains, the more adaptation it requires and the less useful word-for-word equivalence becomes. For global brand campaigns, organisations increasingly budget for transcreation as a distinct activity rather than expecting it to emerge from a standard localisation workflow.

Why the sequence matters

The practical value of these definitions lies in planning. The natural sequence runs from globalisation strategy to internationalised design, and then to repeated localisation for each market. Organisations that localise products designed without internationalisation in mind discover the cost the hard way: reworked code, delayed launches and inconsistent experiences.

Conversely, companies that invest early in flexible architecture find that each additional market becomes faster and cheaper. The first localisation is an effort; the tenth is largely a matter of plugging new language resources into a system built to receive them.

So the next time someone uses these terms interchangeably, the clarification is simple. Globalisation is the strategy, internationalisation is the engineering, localisation is the market-specific adaptation, and translation is the language work inside it. Getting the vocabulary right is the first step toward getting the process right.
