When most people think about interpreting, they picture the moment an interpreter starts speaking. They walk into a room, sit down, and begin a conversation between two people who don’t speak the same language. Simple enough, right?
Not quite.
The truth is that when an interpreter starts speaking, you’re only seeing about 10% of their work. The other 90% often happened days, or even weeks, before they stepped into the room. A successful interpreting assignment begins long before the appointment itself.
It all starts with the brief
When a client contacts us to request an interpreter, our first job isn’t finding someone who speaks the language. It’s gathering information. We need to know the date, time, location, expected duration and, most importantly, the subject matter.
Is it a medical appointment? A legal consultation? A community meeting? These details might seem minor, but they can make a huge difference.
An interpreter who specialises in healthcare may not be the best fit for a court hearing, just as a legal interpreter may not regularly work in hospital settings. Language is only part of the equation. Subject knowledge matters too.
Matching the right interpreter is like solving a puzzle
One of the biggest misconceptions about interpreting is that any interpreter can handle any assignment. In reality, matching an interpreter to a booking is often a surprisingly complex process.
We have to consider language combinations, subject expertise, location, availability, qualifications, experience and sometimes even factors such as dialects or cultural background.
It’s rarely as simple as finding someone who speaks the required language. The goal is always to find the right fit for the environment and the people involved.
Context is king
If there’s one thing that makes an interpreter’s job easier, it’s context.
A good briefing gives the interpreter the who, what and why of an assignment. Who will be attending? What is being discussed? Why is the meeting taking place? Without that information, an interpreter is effectively walking into a maze blindfolded.
Unfortunately, many clients assume interpreters are walking dictionaries who can instantly translate anything put in front of them. As professionals, part of our role is helping clients understand why preparation matters.
The more information an interpreter has beforehand, the more accurate and effective they can be during the assignment.
Building the vocabulary before the appointment
Professional interpreters don’t just turn up and hope for the best.
Before an assignment, they often spend time researching terminology, reviewing documents and preparing glossaries.
They won’t simply rely on general language skills. They’ll familiarise themselves with specialist terminology and ensure they know how key medical concepts are expressed in both languages.
Every field has its own language, and preparation is what allows interpreters to work confidently when the conversation starts.

The work nobody sees
By the time an interpreter walks through the door, much of the hardest work has already been done. They have researched the subject matter. They have reviewed any available documentation. They have prepared terminology. They have thought about potential challenges and considered how best to handle them.
What appears effortless during an appointment is often the result of hours of preparation. That’s one reason why professional interpreting is a skilled profession rather than simply a language ability.
More than just words
At its heart, interpreting isn’t simply about converting one language into another. It’s about helping people understand one another clearly and accurately, often in situations where the stakes are high. That level of communication doesn’t happen by accident. It happens because experienced interpreters prepare, research and plan before they ever enter the room.
So, the next time you see an interpreter at work, remember that what you’re witnessing is only the visible part of the job. Behind every successful assignment is a great deal of work that most people never see. And that’s exactly how it should be.
