Choose the Language Work the Task Needs
A written notice, a conversation, a locally usable service message and a clearer source document need different kinds of work. Translation conveys meaning between languages in written material. Interpretation conveys communication between people using different languages, including spoken and signed communication according to the task. Localization adapts material for a specified setting. Plain-language adaptation makes information easier to find, understand and use. These activities may be combined; they are not interchangeable assurances of quality.
CLEAR Global's plain-language note and TWB's humanitarian interpreting guide, particularly PDF pages 4 and 7-10, provide bounded communication references. The comparison and messages here are original fictional teaching material. They do not certify a language pair or validate an operational plan.
Follow One Message Through Four Tasks
Source message: "The team plans to deliver 12 cartons by 10 November 2026, if road access permits. This is not a confirmed delivery."
The quantity, deadline, condition and unconfirmed status all matter. No real delivery is promised.
| Task | What the Team Needs | Failure to Watch For |
|---|---|---|
| Written translation | A faithful French notice for an audience that reads French | Turning plans into a promise, changing twelve to twenty-four or losing the road condition |
| Interpretation | A supported conversation in which staff and recipients can ask and answer questions across languages | Answering for a participant, omitting uncertainty or interpreting beyond competence |
| Localization | Check the actual audience, date conventions, service terms, channels and local contact arrangements | Silently changing a delivery date or claiming a route is usable without operational evidence |
| Plain-language adaptation | Make the source understandable before or alongside translation | Deleting a necessary condition merely to shorten the sentence |
Inspect a Bounded French Example
One faithful teaching rendering is: "L'équipe prévoit de livrer 12 cartons au plus tard le 10 novembre 2026, si l'accès routier le permet. Cette livraison n'est pas confirmée."
Here, prévoit de livrer expresses a plan; au plus tard le preserves the latest stated date; si retains the condition; and n'est pas confirmée retains the lack of confirmation. A different competent translator may choose different natural wording while preserving those meanings. The illustration has documented desk-review limits, not professional language-pair certification or audience testing. It is not a French or Spanish production release.
Keep Adaptation Decisions Visible
A local reader may need a clearer meaning of carton or the precise receiving place. Ask the author to define the item and the operations owner to confirm the place. Do not solve the gap by inventing contents or a site. If a date is genuinely changed for a local operation, approve the source change and label the adapted notice accordingly; it is no longer merely the same claim translated.
A plain-language source could split the first sentence: "The team plans to deliver 12 cartons by 10 November 2026. Delivery depends on road access. The delivery is not confirmed." That keeps the material qualifications. "Your 12 cartons will arrive on 10 November" changes a plan into a promise and by into on. It is shorter but different.
Assign the Right Checks
The source owner resolves facts and commitments. Competent language reviewers check meaning and natural use for the intended audience. A context owner checks whether the actual service, contact route and conditions apply. For sensitive or specialist communication, obtain the necessary specialist and local review. Translation cannot supply missing evidence or permission to share data.
