Your First AI Prompts as a Linguist
A "prompt" is just the instruction you give an AI tool. The quality of your prompts is the single biggest lever you have over the quality of AI output. Good prompts produce usable terminology lists, accurate context summaries, and clean drafts. Bad prompts produce confident-sounding nonsense.
This lesson walks you through the building blocks of prompts that work for translation and interpreting tasks — and gives you a starter pack you can use today.
What You'll Learn
- The four parts of any effective prompt for linguistic work
- How to give an AI the context it needs to translate accurately
- Ten copy-paste prompts for common translator and interpreter tasks
- Why specifying your language pair, register, and audience changes everything
The Anatomy of a Linguist's Prompt
A useful prompt for translation work almost always contains four parts:
- Role — Tell the AI who it is. "You are an experienced legal translator working between Spanish and English."
- Task — State what you want, very specifically. "Translate the following Spanish contract clause into English."
- Constraints — Spell out the rules. "Preserve the formal register. Do not localize Spanish legal terminology that has no direct English equivalent — instead, keep the Spanish term in italics and add a translator's note in square brackets."
- Material — Provide the text, glossary, or context.
Compare these two prompts:
Weak: "Translate this to English: El presente contrato se regirá por las leyes del Reino de España."
Strong: "You are an experienced legal translator working from Spanish to UK English for a London-based law firm. Translate the following clause from a service agreement. Preserve formal register. Use 'shall' for legal obligation. Keep British English spelling. Text: El presente contrato se regirá por las leyes del Reino de España."
The first prompt produces a generic, often US-flavored output. The second produces a draft you can actually use.
Always Tell the AI Your Language Pair
Surprisingly often, translators paste a sentence with no indication of source or target. LLMs will guess — and they guess wrong. Always state:
- Source language and variant: "European Portuguese", not just "Portuguese"
- Target language and variant: "Latin American Spanish for a Mexican audience"
- Register: formal/informal/legal/medical/marketing/literary
- Audience: who is the end reader
This one habit eliminates roughly half of the "AI got it wrong" moments.
Ten Starter Prompts for Daily Use
Copy these into ChatGPT, Claude, or Gemini and adapt to your language pair.
1. Terminology disambiguation
"You are a senior medical translator (EN → FR). The English term 'lead' appears in the source text below. Given the context, which French equivalent is correct, and why? Provide three plausible French options ranked by likelihood. Source paragraph: ..."
2. Register check
"Read the following German draft and tell me whether the register is appropriate for a corporate press release aimed at institutional investors. Identify any words that are too colloquial or too technical, and suggest replacements. Draft: ..."
3. Domain glossary on the fly
"I am translating a 6,000-word user manual for a domestic ultrasonic humidifier from Japanese to Brazilian Portuguese. Generate a starter glossary of 25 key terms in JA → pt-BR. Format as a table: Japanese term | Romaji | Suggested pt-BR | Domain notes."
4. Cultural adaptation
"I'm localizing a UK retail email campaign for the German market. The English copy mentions 'Boxing Day sales' and 'tea time savings'. Rewrite for a German audience while preserving the marketing intent and seasonal positioning."
5. Source-text comprehension
"Explain the following French civil code excerpt in plain English. Identify any terms that have no direct English equivalent and require a translator's note. Excerpt: ..."
6. Idiom analysis
"The Spanish source uses 'tirar la casa por la ventana.' Give me five English idioms or phrases that convey the same meaning, ranked from formal to informal, and tell me when each is appropriate."
7. Consistency QA
"Below are 12 segments from a translation I just finished, EN → ES. The same English term 'stakeholder' appears in eight of them. Check whether I used a consistent Spanish equivalent. Flag inconsistencies and suggest the best single term for the whole document. Segments: ..."
8. Interpreter background brief
"I will interpret consecutively (FR ↔ EN) at a 90-minute meeting between a French aerospace firm and a Canadian government regulator about drone certification. Generate a one-page background brief covering: key Canadian and French regulatory bodies, current legal framework, typical terminology, and likely points of friction."
9. Email to client
"Draft a polite, professional email in English declining a rush translation job offered at standard rates because the timeline (8,000 words in 24 hours) is unrealistic. Offer two alternative options: a higher rush rate or a longer deadline."
10. Style guide alignment
"I am translating into Canadian English for a federal-government client. Here is a 200-word draft. Check it against the Translation Bureau's Canadian style guide for: spelling, gender-inclusive language, official titles, and bilingual conventions. Highlight any deviations. Draft: ..."
A Prompt That Won't Work — and Why
"Translate this into French and make it sound nice."
This fails because "nice" is undefined, the variant of French (France, Canadian, African) is unspecified, the register is unspecified, the audience is unspecified, and the AI has no reason to choose one good option over another good option. The output will be a fluent shrug.
Verify Before You Ship
A prompt is the first half of the loop. The second half is your verification. After every AI output, ask:
- Does this term appear in an authoritative bilingual source (IATE, UN terminology, Termium, glossaries from the client's industry body)?
- Does the register match what the client asked for?
- Has the AI silently dropped or added a fact from the source?
This is where your craft enters. The AI is fast; you are accurate.
Key Takeaways
- Every prompt should specify Role, Task, Constraints, and Material.
- Always declare your source and target language variant, register, and audience.
- Pre-built starter prompts save time on terminology, register, glossaries, idioms, and client emails.
- AI output is a first draft. Your verification against authoritative sources is what makes it professional work.
