If you work in an international team, sell to customers abroad or moderate a multilingual community, a lot of what you write will be read through a translator or by someone reading in their second or third language. The good news is that you have a lot of control over how well that goes. A few writing habits make the difference between a message that arrives intact and one that confuses everyone.
Why your writing style matters
Machine translation works best on text that is complete, explicit and unambiguous. Native speakers, especially in casual chat, tend to write the opposite way: fragments, shared context, jokes, abbreviations. A human colleague in the same office fills in the gaps. A translator, or a reader in another language, cannot.
None of the tips below make your writing sound robotic. They are the same habits that make any text clearer.
1. One idea per sentence
Long sentences with several clauses give the translator more chances to attach a phrase to the wrong part. Compare:
- Hard: "Since the release got pushed, which we flagged last week, the client, who hasn't seen the new build, wants a call before Friday."
- Easy: "The release was delayed. We flagged this last week. The client has not seen the new build yet, so they want a call before Friday."
The second version is slightly longer and much harder to mistranslate.
2. Keep the subject in the sentence
In chat we often drop the subject: "Checked it, looks fine, will merge tomorrow." Who checked? Who will merge? Many languages require a subject, so the translator guesses. Write "I checked it. It looks fine. I will merge it tomorrow."
3. Avoid idioms, sarcasm and puns
"Let's touch base", "that ship has sailed", "piece of cake", "the ball is in your court": all perfectly clear to a native speaker, and all at risk of being translated literally. Sarcasm is worse, because the translation keeps the words and loses the tone, so "great, another meeting" can arrive as sincere enthusiasm.
Say what you mean directly: "Let's talk again next week", "It is too late to change that", "This is easy", "It is your decision now".
4. Be careful with abbreviations and slang
Internal acronyms, texting shorthand (np, tbh, iirc) and industry jargon may not be recognised at all. The translator either leaves them untouched or, worse, guesses. Spell things out the first time, and prefer the full phrase in any message that will go to people outside your team.
5. Write dates, times and numbers unambiguously
- Write dates with the month as a word: "4 March 2026" instead of "03/04/26".
- Include a time zone for anything scheduled: "15:00 UTC" or "3 pm Berlin time".
- Use digits for numbers and add the unit or currency: "1,500 EUR", "20 km".
- Avoid "next Friday" when "Friday 12 September" is just as easy to write.
6. Use the same word for the same thing
Writers are taught to vary vocabulary to avoid repetition. In translated text that backfires: if you call something a "ticket", then an "issue", then a "request", the reader may think you mean three different things. Pick one term and stick to it.
7. Use lists and structure
Bullet points and numbered steps survive translation very well, because each item is short and self-contained. If a message contains instructions, options or questions, put them in a list. It also makes it easier for the reader to answer point by point.
8. Check your spelling
A human reader skims past a typo. A translator may not: a misspelled word can be treated as a name and left untranslated, or matched to a completely different word. Run a spell check before sending anything important.
9. Test important messages
For a message that really matters, such as a price quote, a policy change or an apology to a customer, paste it into a translator, translate it into the reader's language and then back into yours. If the round trip keeps your meaning, you are in good shape. If something comes back strange, rephrase that sentence.
10. Make it easy to reply
End with a clear question or next step. "Can you confirm by Thursday whether option A or option B works for you?" is easier to answer across a language barrier than "Let me know what you think."
A quick before-and-after
Before: "Hey! Quick one: we're gonna push the demo, ball's in marketing's court now, so ETA is TBD. Ping me if that's a dealbreaker."
After: "Hi! We are moving the demo to a later date. The marketing team will choose the new date. I will send it to you as soon as I know it. Please tell me if this delay is a problem for you."
The second version is plain, but every sentence will survive translation into any language, and a non-native reader can understand it without a translator at all.
The bottom line
Writing for translation is simply writing clearly: short complete sentences, explicit subjects, no idioms, consistent terms, unambiguous dates and numbers. It takes a few extra seconds per message and saves a lot of follow-up questions and misunderstandings.
