How to use this glossary at an event

A technical glossary is only valuable when it reaches the interpreter before the event. In practice, the most effective use is to cross-check the terms on this page against your event materials: the presentation, the agenda, the participants' names and the company's internal acronyms. The terms listed here are a sample of 50 out of the 2,233 that lingo maintains, and serve as a reference for those who hire and want to understand the level of preparation involved.

Acronyms deserve special attention. In Portuguese and in English, the same acronym can mean different things depending on the sector — MLM, for example, can be multi-level marketing or machine learning. When the interpreter receives the context beforehand, ambiguity is avoided and the right term is delivered on first use, with no hesitation or later correction.

Another point is the choice between keeping a term in English or translating it. In the Brazilian financial market, expressions such as earn-out, carried interest and clawback are usually used in English even in meetings held in Portuguese. The interpreter needs to know the audience's convention: an international fund's board may prefer the original term, while an audience of executives from a family-owned company may need the explanation in Portuguese.

How the glossary is built and maintained

lingo's vocabulary was accumulated in real engagements over 21 years, not in theoretical study. Every event served adds terms, acronyms and product names to the collection, and in recurring engagements the client's glossary grows session after session. This process is what allows the interpreter to speak as naturally as the executive in the field, instead of relying on word-for-word translation.

Event-specific preparation complements the general glossary. Alex Barros requests the presentation and agenda 48 hours in advance to build the list of terms for that event, including proper names, internal metrics and company jargon that do not appear in dictionaries.

Frequently asked questions about terminology

Is the full glossary available? It is consulted internally when preparing each engagement; clients receive the glossary specific to their event. Are terms translated literally? No: the interpreter uses the equivalent established in the sector, which is often the English term itself. Which languages are covered? The collection covers 16 languages, and Alex Barros works English–Portuguese directly; for the other pairs, lingo relies on interpreters with native fluency and documented corporate experience.
