English for Translation: Essential Vocabulary & Phrases

"translation memory"

A database that stores previously translated text segments so they can be reused when the same or similar source text appears again, improving consistency and speed

"After completing the project, the translator updated the translation memory with all approved segments so future documents from the same client would be handled faster."

"fuzzy match"

A translation memory suggestion where the stored segment is similar but not identical to the current source text, typically expressed as a percentage of similarity

"The 75% fuzzy match saved the translator from starting from scratch, but still required careful editing to account for the changed product name."

"concordance search"

A search within a translation memory or glossary to find every instance where a particular term or phrase has previously been translated, used to check consistency

"Before finalising the term "data controller", the linguist ran a concordance search to ensure it had been rendered consistently throughout all previous documents."

"termbase"

A structured database of approved terminology, definitions, and contextual information for a project or client, used to enforce consistent term usage

"The agency shared its client-approved termbase with all team members before work began so that product names and technical terms would be uniform across all files."

"XLIFF"

An XML-based open standard file format for exchanging localisation data between different software tools, allowing translators and reviewers to work in separate environments

"The developer exported the application strings in XLIFF format and handed the file to the translation agency without needing to give access to the source code."

"machine translation post-editing"

The process of reviewing and correcting output produced by a machine translation engine to produce a text that meets human quality standards

"The agency offered machine translation post-editing as a faster alternative for high-volume technical documentation where speed was prioritised over stylistic refinement."

"translation management system"

A software platform that automates and manages the entire translation workflow, from project creation and vendor assignment through to delivery and invoicing

"Once the translation management system was integrated with the content platform, new articles were automatically routed to the appropriate language team for translation."

"leverage"

The proportion of a new document that matches previously translated content in a translation memory, directly reducing the amount of new translation work required

"Because the updated manual had 60% leverage against the previous version, the translator was only charged a reduced rate for the matching segments."

"simultaneous interpreting"

A mode of interpreting in which the interpreter renders the speaker's words into the target language at the same time as the speaker is talking, typically from a soundproof booth

"During the UN General Assembly, simultaneous interpreting teams worked in four-language booths, each pair taking turns every 30 minutes to maintain concentration."

"consecutive interpreting"

A mode in which the interpreter listens to a complete unit of speech, takes notes, and then delivers the interpretation after the speaker has paused

"The diplomatic dinner used consecutive interpreting, with the interpreter delivering a full rendering of each statement before the next delegate spoke."

"chuchotage"

Whispered interpreting in which the interpreter sits beside one or two listeners and delivers a simultaneous interpretation in a low voice without any technical equipment

"The CEO's personal assistant provided chuchotage during the bilateral meeting, leaning close to whisper the translation without disturbing the other participants."

"relay interpreting"

A system in which one interpreter translates from the source language into a pivot language, and other interpreters then translate from that pivot into their respective target languages

"With no Basque interpreters in the English booth, the team used relay interpreting via the Spanish channel as the pivot language."

"sight translation"

The immediate oral rendering of a written text without prior preparation, combining the skills of reading and interpreting simultaneously

"The immigration officer asked the community interpreter to provide sight translation of the applicant's birth certificate, which had not been pre-translated."

"boothmate"

The interpreting colleague who shares a conference booth with another interpreter, monitoring the output, providing terminology support, and taking over at regular intervals

"Her boothmate quietly passed a note with the correct technical term just before she needed to say it, preventing an awkward pause in the interpretation."

"retour"

An interpreting language combination in which the interpreter works into a language that is not their mother tongue, known as their B or C language

"Very few simultaneous interpreters can work retour from English into Chinese at conference quality, making Mandarin a highly sought-after combination."

"remote simultaneous interpreting"

A system in which interpreters work from a location outside the meeting venue, delivering interpretation via an online platform rather than an on-site booth

"After the pandemic, many international organisations adopted remote simultaneous interpreting as a permanent option for hybrid conference formats."

"internationalisation"

The process of designing a product or content in a way that makes it easy to adapt for different locales without engineering changes, often abbreviated as i18n

"The development team invested in internationalisation from the start, separating all user-facing strings into external files so any language could be added later without touching the core code."

"locale"

A specific combination of language, region, and cultural conventions — such as date formats, currency symbols, and number separators — that defines how content should be presented

"The children's app required significant cultural adaptation for the Japanese market, replacing Western holiday references with locally recognised festivals and food items."

"pseudo-localisation"

A testing technique in which source text is replaced with modified characters to simulate translation without real linguistic content, used to detect layout problems before actual localisation

"Running pseudo-localisation revealed that the German strings, which are typically 30% longer than English, would overflow several UI buttons in the current design."

"string freeze"

The point in a software development cycle at which all user-facing text is finalised and no further changes are allowed so that translation can begin without rework

"The product manager announced a string freeze two weeks before the launch date, giving the localisation team enough time to complete all 14 language versions."

"desktop publishing"

The post-translation process of reformatting and laying out translated documents to match the visual design of the original, accounting for text expansion and different character sets

"After translation, the Arabic version required extensive desktop publishing work to convert all text boxes to right-to-left layout and adjust the document's visual hierarchy."

"glossary management"

The systematic creation, maintenance, and distribution of approved terminology lists to ensure that key terms are translated consistently across all languages and materials

"The localisation manager introduced a monthly glossary management review to incorporate new product terms before they entered the main translation pipeline."

"back translation"

The process of translating a translated text back into the original language by an independent translator, used to check accuracy especially in clinical and legal documents

"four-eyes principle"

The quality assurance practice of having every translation reviewed by a second qualified linguist before delivery, to catch errors the original translator may have missed

"Under the agency's standard workflow, the four-eyes principle meant that even urgent same-day deliveries were reviewed by a second linguist before being sent to the client."

"MQM framework"

The Multidimensional Quality Metrics framework, a hierarchical system for categorising and rating translation errors used widely in professional quality evaluation

"The client used the MQM framework to score translations on a 100-point scale, deducting points for accuracy, fluency, style, and terminology errors."

"MTPE threshold"

The minimum quality level that machine translation output must reach before it is considered acceptable for post-editing rather than full human translation

"The agency set a strict MTPE threshold, rejecting engine output that fell below 60% usability and routing those segments to full human translation instead."

"in-country review"

A quality check performed by a subject-matter expert or representative of the target market who evaluates the translation for cultural appropriateness and local accuracy

"The legal firm requested an in-country review by a qualified German solicitor to confirm that the translated contract terms had the correct legal force under German law."

"linguistic validation"

A rigorous quality process applied to clinical outcome measures and patient questionnaires to confirm that translated instruments are conceptually equivalent to the source version

"error typology"

A systematic classification of the types of errors that can occur in a translation, such as omission, addition, mistranslation, register, grammar, and punctuation

"The translator development programme used a detailed error typology so that feedback could be structured and trainees could identify patterns in their own mistakes."

"translation brief"

A document provided by the client or project manager specifying the purpose of the translation, target audience, required register, style guidelines, and any special instructions

"Without a translation brief, the team had to make assumptions about the audience, which led to avoidable revision requests when the client saw the delivered text."

"sworn translation"

"The immigration authority would not accept the applicant's birth certificate without a sworn translation bearing the official seal of a registered court translator."

"subtitling"

The preparation of timed on-screen text that conveys the dialogue and key sound information of an audiovisual work, subject to strict space and timing constraints

"The subtitling guidelines required a maximum of 42 characters per line and a minimum reading time of one second per subtitle to ensure accessibility for all viewers."

"dubbing"

The replacement of the original dialogue in a film or video with a recorded version in the target language, synchronised to match the lip movements of the on-screen characters

"The children's animation was prepared for dubbing into eight European languages, with each version recorded in a different studio to capture local voice acting styles."

"patent translation"

The highly technical translation of patent documents requiring both linguistic precision and knowledge of intellectual property law to preserve the legal scope of claims

"A single poorly translated claim in the patent translation had the potential to narrow the client's intellectual property protection in the target jurisdiction."

"legal translation"

The translation of legal texts such as contracts, judgements, legislation, and court documents, requiring both linguistic skill and sound knowledge of both legal systems involved

"literary translation"

The translation of creative works — novels, poetry, drama, and short stories — prioritising artistic and cultural resonance over literal accuracy

"The literary translation of the prize-winning novel was praised for capturing the author's dark humour and regional dialect rather than merely rendering the surface meaning."

"audiovisual translation"

An umbrella term for the translation of content that combines moving image and sound, including subtitling, dubbing, voice-over, and audio description

"The streaming platform's investment in high-quality audiovisual translation was credited with making its foreign-language content accessible and popular in new markets."

"per-word rate"

The most common pricing model for translation work, where the translator is paid a fixed fee for each word in the source or target text

"Her per-word rate for Spanish medical translation was higher than her general rate because of the specialised research and terminology verification each document required."

"minimum fee"

A base charge applied to projects that fall below a certain word count, ensuring that very short translations are still economically viable for the translator

"The freelancer applied a minimum fee of £40 to cover the overhead of accepting and delivering even a single-sentence legal certificate."

"NDA"

A non-disclosure agreement — a legal contract in which the translator agrees not to share confidential information received from the client during a project

"The agency pursued ISO 17100 certification to demonstrate to enterprise clients that every project followed a documented two-step translation and revision workflow."

"direct client"

An end client who engages the translator directly rather than through a translation agency, typically offering higher per-word rates and longer-term relationships

"After five years working through agencies, she shifted her business model toward direct clients in the legal sector, which doubled her effective hourly rate."

"specialisation"

The practice of focusing on one or more subject-matter areas — such as finance, pharmaceuticals, or law — to command higher rates and build a reputation in a defined niche

"His decision to pursue a specialisation in oil and gas contracts proved lucrative as demand in that niche far outstripped the supply of qualified translators."

"CPD"

Continuing professional development — ongoing training, courses, conferences, and self-study that translators and interpreters undertake to maintain and expand their skills

"The professional association required members to log at least 30 hours of CPD per year to retain their certified membership status."

"vendor management"

The process by which a translation agency recruits, tests, onboards, rates, and allocates work to freelance translators and other linguistic vendors

"The new vendor management portal allowed project managers to search the freelancer database by language pair, specialisation, and availability before assigning work."
