Professional writing in English: practical tips for non-native speakers

If you write English as a second (or third) language for work, the challenge is rarely grammar — it is the small idiomatic choices that make a message feel natural rather than translated. A sentence can be perfectly correct and still read as slightly formal, stiff or unusual to a native ear. The good news is that a handful of habits close most of that gap.

Prefer plain, common words

Textbooks often teach elaborate vocabulary, but native professional writing leans plain. "Use" reads more naturally than "utilise", "help" beats "facilitate", and "about" is better than "regarding" in most emails. Simple words are not less intelligent — they are what fluent writers actually reach for.

Use contractions in everyday messages

Writing out "I am", "we will" and "do not" in a casual email can make it feel oddly formal. In most day-to-day work messages, "I'm", "we'll" and "don't" read as warmer and more natural. Save the fully written-out forms for formal documents.

Watch the highest-frequency traps

• Articles: "the report" vs "a report" vs "report" — a missing or wrong "the/a" is a common tell.
• Prepositions: "on Monday", "in June", "at 3pm" — these pairings are worth memorising as chunks.
• Over-formal openers: "I hope this email finds you well" is fine occasionally but often skippable.
• Direct translations of idioms rarely work — when unsure, say it plainly instead.

Keep one idea per sentence

Long, multi-clause sentences are where small errors pile up and clarity drops. Breaking a thought into two shorter sentences almost always reads better and is far easier to get right. Native readers do not notice short sentences as "simple" — they notice them as clear.

Read it aloud (or have a tool check it)

Reading a message aloud catches phrasing that looks fine but sounds unnatural. If a sentence is hard to say smoothly, it is usually worth rewording. A grammar and rewriting tool can do the same job in seconds when you do not have a native colleague to ask.

iTextwise is built for exactly this. Run a draft through the Grammar Checker to catch mechanical slips, then use Rewrite Text with a "make this sound more natural" instruction to smooth the phrasing — while keeping your meaning, names and numbers exactly as you wrote them.
