Day 10: Understand Expert Language

The Concept

Specialist language exists, in part, because specialists think in the concepts their field uses. A doctor writing to a patient uses clinical terminology not to confuse them but because that is the language their colleagues use and they have not paused to translate. A solicitor writes in legal language because precision matters and imprecision has consequences. The language is not a deliberate barrier — it is simply not adapted for a lay reader.

The practical effect, though, is real. People sign documents they do not fully understand, nod along in appointments without being sure what was said, or file important letters without acting on them because it was unclear what action was needed. The gap between what was written and what was understood has real consequences.

What AI can do here — and what it cannot

AI is very good at translating specialised language into plain English. This is because translation between registers — from clinical to clear, from legal to everyday — is fundamentally a language task, and language is AI's strongest domain. Given a dense passage from a medical letter or a legal contract, AI can consistently explain what it says, what the key terms mean, and what you need to pay attention to.

What AI cannot do is give you professional advice. This distinction matters. AI can explain what a clause in a contract says; a solicitor can tell you whether you should sign it. AI can tell you what a diagnosis means in plain language; a doctor can tell you what it means for your specific history and circumstances. Use AI to understand words and prepare better questions. Use professionals to make decisions that carry real consequences.

The document types this helps with most

Medical correspondence — letters from consultants, discharge summaries, results letters, care plan documents — is often dense with clinical terminology and abbreviations that are precise in a medical context but opaque to a patient. Understanding what a letter actually says, and what question to ask at your next appointment, is a meaningful improvement regardless of what you decide to do.

Legal documents — tenancy agreements, employment contracts, terms and conditions, court letters — are precise by design, which makes them long and complex by design. Understanding which clauses actually affect you, and what you would be committing to, is something AI can help with before you decide whether to involve a professional.

Financial and insurance documents combine financial jargon with regulatory language and conditional clauses. Annual pension statements, mortgage offers, and insurance policy wording all benefit from plain-English translation before you act on them.

How to get the most from this

The prompt for today goes beyond requesting a plain-English explanation. It asks AI to identify the three most important things, flag terms worth following up on, and generate questions for a professional. That last part is particularly valuable — arriving at a medical or legal appointment with specific, informed questions produces a significantly better conversation than arriving without them. Claude is particularly good at this kind of document analysis. Do not include personal identifiers such as your name, date of birth, or patient number — they are not needed for the explanation.
