4.3 Translation and register: EN ↔ NE, formal ↔ colloquial
Language models translate — but 'translate' hides five different jobs. Direction, register, romanization, and the things that must never be translated.
Modern models are excellent translators for the languages they’ve seen a lot of, and English–Nepali is well-represented. But “translate this to Nepali” hides a dozen small choices that matter. The best translation prompts pin those choices down.
The five decisions to make explicit
1. Direction. English to Nepali, Nepali to English, or something else (Newari, Maithili, Hindi)? Never rely on the model to guess — say it.
2. Script. Nepali written in Devanagari (नमस्ते) or in Latin/Romanized (namaste)? For messaging apps and social media, Romanized is often what you want. For formal writing, Devanagari.
3. Register. Formal (news, official) vs colloquial (chat, blog, YouTube). “Translate to Nepali” defaults to a mid-formal literary register that reads a bit stiff for a friendly WhatsApp message.
4. Regional variant. Nepali as spoken in Kathmandu differs from Nepali in the Terai; Hindi loanwords are heavier in some contexts than others. Say which flavour you want.
5. What to NOT translate. Brand names, place names, product names, technical terms — usually leave them in the source language.
A prompt that gets it right
Translate the English text below into Nepali.
Rules:
- Script: Devanagari.
- Register: colloquial, suitable for a customer-service WhatsApp message.
- Do not translate: proper nouns (Khalti, Kathmandu, Pathao), technical
terms in English (OTP, PIN, KYC), or numbers.
- Preserve line breaks.
<source>
Your OTP is 4-8-2-1-5. Do not share this OTP with anyone. Khalti will
never ask for your PIN. If you did not request this OTP, please
contact support.
</source>Expected output preserves “OTP,” “PIN,” and “Khalti” verbatim, uses friendly casual Nepali, and keeps the numeric OTP untouched.
Romanized Nepali
When your target is a chat interface or SMS:
Translate to Romanized (Latin-script) Nepali using the informal
spellings people actually type on WhatsApp.
Rules:
- Do not use Devanagari.
- Use the spellings most common in Nepali social media (e.g. "kasto"
not "kasṭo," "cha" not "chha").
- Preserve proper nouns as in the source.
<source>
Where are you? I'm running late.
</source>Expected: something like “Kaha chau? Malai dhilo bhairaacha.”
Translating culturally-loaded terms
Some concepts don’t map. Options:
- Loan-word. Keep the source term and add a parenthetical gloss. “sekuwa (grilled meat skewers).”
- Cultural equivalent. Substitute a familiar concept from the target audience’s context. “high tea” → “khaja time.”
- Descriptive translation. Rewrite the phrase to convey meaning, not literal words.
Tell the model which strategy you want, or it’ll pick one and you may not like the choice:
For culturally-specific terms in the source, prefer loan-words with a
short parenthetical explanation on first mention. Do not substitute
foreign cultural equivalents.When translation quality is critical
- Round-trip check. Translate to Nepali, then translate the Nepali back to English with a different prompt. If the back-translation drifts far from the original, the forward translation likely did too.
- Human review for names and numbers. Even the best models occasionally mangle Nepali proper nouns or transpose digits.
- Use professional translation for legal or medical text. Same rule as 3.4: models are drafting tools, not authoritative sources.
Translating from Nepali (the harder direction)
English-to-Nepali is generally stronger than the reverse. When translating from Nepali to English:
- Give context. “This is a customer complaint about a payment issue” helps the model resolve ambiguous phrasing.
- Handle honorifics. “तपाईं” and “तिमी” both translate to “you” — but the tone shift matters. Ask the model to preserve register: “convey the level of formality, not just the literal meaning.”
- Watch for missed idioms. Nepali proverbs and idioms don’t cleanly translate; the model will try to render them literally. Add “if you encounter an idiom, translate the meaning and add the literal phrasing in parentheses.”
