Discover what a translation and localisation glossary is, why it is vital for multilingual projects, how to create an effective glossary, and examples by sector to maximise consistency and quality.
What we're going to explore:
What is a glossary?
A glossary is an organised list of terms from a particular domain or project, accompanied by their definitions and, in the case of translation/localisation, the approved translations of those terms.
This resource serves as a reference to clearly ensure how words and expressions should be interpreted and translated in the context of your project.
In the context of translation and localisation, a glossary is more than just a catalogue of terms: it is a strategic tool that ensures terminological consistency, reduces ambiguity and guarantees that all stakeholders use the same approved vocabulary throughout the project.
Glossary vs. Dictionary vs. Termbase
Although a glossary, dictionary and termbase are all related to terms and definitions, they have distinct functions:
- Glossary: list of terms and translations/contexts specific to a project or area.
- Dictionary: a general resource that explains the meanings of words and expressions in a language.
- Termbase: technical version of the glossary stored in assisted translation systems, with metadata, categories and rules for integration into automatic translation flows.
Why is a translation glossary vital for your project?
A well-designed glossary brings measurable benefits to any translation or localisation project:
- Terminological consistency: ensures that key terms are used uniformly across all texts.
- Greater accuracy: reduces the risk of incorrect or ambiguous translations.
- Increased efficiency: prevents translators from wasting time on repetitive research.
- Improved collaboration: everyone involved in the project, such as translators, proofreaders and managers, works with the same reference.
A glossary is particularly useful when working with technical terminology, specific marketing or texts that circulate between several language markets. Contexts where precision makes a difference in the end result.
Localisation glossary: where it enters the workflow
In a localisation project (such as websites, software or global content), the glossary is a living resource that should be used at all stages:
- Pre-project: identifies and selects the most critical terms for communication.
- During translation: serves as an active reference for translators and proofreaders.
- Post-translation: helps maintain consistency in future updates and revisions.
Its integration with localisation and project management tools, such as those that support your team’s workflows in services such as Dokutech’s project management, enhances quality and reduces rework.
Glossary example (structure and recommended fields)
An effective glossary for translation/localisation may include the following fields:
- Term: original word or expression.
- Approved translation: final version in the target language.
- Definition/context: brief explanation for correct use.
- Usage notes: indications of when not to translate or regional variations.
This structure makes it easy to consult for both experienced translators and those joining a translation project for the first time.
How to create a glossary for your localisation project (step by step)
1. Extract relevant terms
Identify, from the source content, the words and expressions that are:
- sector-specific;
- frequent or with a technical meaning;
- likely to generate ambiguities.
2. Define clear context
Include an example sentence or context of use for each term. This helps to avoid misinterpretations during translation.
3. Approve with stakeholders
Involve product, marketing or compliance teams (where applicable) to validate critical terms.
This ensures that the glossary is aligned with corporate communication and brand expectations.
Isto garante que o glossário está alinhado com a comunicação corporativa e com as expectativas de marca.
4. Use in the translation workflow
Incorporate the glossary into review processes and assisted tools to translate based on approved terms.
When used well, it reduces time spent on reviews and increases confidence in the final result.
5. Maintain and update
The glossary should evolve over time, because new terms may emerge and some may become obsolete. Update it regularly to keep it useful.
Translation glossary by sector (practical examples)
Each sector has its own terminology, conventions and levels of risk. Therefore, a translation glossary by sector is essential to ensure accuracy, consistency and compliance, especially in recurring projects or those with multiple translators involved.
In practice, sector-specific glossaries allow you to work with thousands of professionally validated terms, adapted to the most common use cases in different industries, reducing errors, rework and ambiguities.
Below we highlight some critical examples, followed by an overview of the sectors where specialised glossaries make all the difference.
Glossary of medical terms
Medical glossaries are crucial for accuracy and safety, as an error in a clinical, pharmaceutical or technical term can seriously compromise the meaning of a document, report or instruction.
This type of glossary includes, for example:
- clinical and anatomical terminology
- names of medical procedures and devices
- active ingredients, dosages and routes of administration
- regulatory documentation and clinical trials
In medical and pharmaceutical translation, a glossary is not just good practice. It is a quality requirement.
Civil aviation glossary
In the civil aviation sector, terminology is highly standardised and context-sensitive. Many acronyms and expressions such as V1, balancing and weights, emergency procedures or operations manual, cannot be translated intuitively.
An aviation glossary ensures:
- consistent use of technical terms and acronyms
- alignment with international standards
- clarity in manuals, training and operational documentation
Here, terminological consistency is directly linked to safety and compliance.
Real estate glossary
The real estate sector combines commercial and legal language, which requires special care. Terms such as promissory contract of purchase and sale, credit authorisation, registration, land registry or deed require clear definitions and rigorous translations.
A real estate glossary helps to:
- avoid legal ambiguities
- align concepts between different markets
- Ensure clarity in contracts, advertisements and official documentation.
This is particularly important in international projects or cross-border transactions.
Other sectors where specialised glossaries are essential
In addition to the examples above, translation and localisation glossaries are widely used in many other sectors where specific terminology is critical to the quality of the content:
- Automotive
- Certificates, diplomas, licences and curriculum
- Social sciences
- Accounting and finance
- Cosmetics
- Cooking and food
- Law
- Electronics and electrical engineering
- Energy, oil and gas
- Internet and e-commerce
- Marketing, advertising and public relations
- Mechanics and industrial production
- Environment
- Fashion
- Music
- Banking sector
- Chemical sector
- Information Technology (IT)
- Travel and tourism
In all these areas, glossaries allow you to work with validated terminology, appropriate to the technical, legal or commercial context, and adapted to the expectations of the target audience.
Why do sector-specific glossaries make a difference?
Regardless of the area, a well-structured glossary:
- increases the clarity of the content
- ensures terminological consistency
- reinforces customer and end-user confidence
- reduces revisions, costs and risks
That is why sector-specific glossaries are now as strategic assets in translation, localisation and corporate language services projects.
Common mistakes when creating a glossary (and how to avoid them)
- Lack of context: terms without examples make interpretation difficult.
- Terms that are too general: only include those that really need guidance.
- Lack of governance: without those responsible for updating it, the glossary becomes obsolete.
- Non-integration with the workflow: a glossary that nobody uses loses its usefulness.
How a glossary improves other areas (and services)
Having a structured glossary not only raises the quality of translation work, but also improves the delivery of language services in general, positively impacting flows such as:
- Traditional technical and creative translation with support from our translation services team.
- Corporate processes and knowledge management, integrating glossaries into corporate platforms aligned with corporate language services.
- Management of complex translation projects where the glossary is one of the pillars of planning and continuous review, as we explain in project management.
Conclusion
A translation and localisation glossary is not just a reference document. It is a strategic asset that guarantees:
- terminological consistency;
- cultural and technical accuracy;
- time and cost savings;
- better communication between teams and stakeholders.
If you are preparing a translation or localisation project, whether for a global website, software or specialised documentation, start by creating a solid glossary. Using one improves both the quality and efficiency of the process.
