French and English share an enormous amount of vocabulary — the Norman Conquest of 1066 brought thousands of French words into English, and the two languages have been exchanging vocabulary ever since. For French speakers learning English professionally, this creates a specific problem: enough words look identical or similar that you feel confident using them without checking, but enough of them mean something different that false-friend errors accumulate quietly.
The challenge is that false friends rarely produce an obvious error. A sentence like "I will eventually finish the report" is grammatically correct English. But if you used "eventually" because you meant "possibly" (French "éventuellement"), the sentence says something different from what you intended. Your English-speaking colleague reads it, understands it perfectly — but understands something you did not mean.
This article covers the false friends that cause the most professional friction in workplace writing, with the French meaning clarified alongside the English one.
The Core False Friends
Eventually / Éventuellement
French: possibly, perhaps. "Il viendra éventuellement" = He might come.
English: at some unspecified future time. "He will eventually arrive" = He will arrive, but we don't know when.
Before: "I can eventually provide the data if needed." (meaning: I can possibly provide it)
After: "I can provide the data if needed." or "I may be able to provide the data if needed."
Actually / Actuellement
French: currently, at the moment. "Il travaille actuellement sur le projet" = He is currently working on the project.
English: in fact, really (to correct a misunderstanding or emphasise a truth). "He actually finished it yesterday."
Before: "I am actually working on a new initiative." (meaning: I'm currently working on it)
After: "I'm currently working on a new initiative."
Assistance / Assistance
Both words exist. But "assist" in English is more limited than the French "assister à" which means "to attend." "I assisted the meeting" is not English — "I attended the meeting" is.
Before: "I assisted the launch event."
After: "I attended the launch event."
Sensible / Sensible
French: sensitive, emotional. English: reasonable, practical, having good sense.
Before: "The team was sensible about the criticism." (In English this means: the team took the criticism reasonably well. This might be what you mean.)
Watch out if you meant: "The team was upset by the criticism" — that would be: "The team was sensitive to the criticism."
Proper / Propre
French: clean, own. English: appropriate, correct, or (in formal usage) related to a specific person or thing.
Before: "Please return the tools to their proper place." ✓ This is correct English.
The false-friend trap: "The office is very proper" meaning "the office is very clean" — an English reader would interpret this as: the office is very formal or decorous.
Demand / Demande
French: a request, an application. English: a strong claim or requirement, with an expectation of compliance.
Before: "I have a demand for you." (meaning: I have a request for you)
After: "I have a request." or "I have a question for you."
"Demand" in English carries assertive or coercive overtones. "Request" is the neutral equivalent.
Comprehensive / Compréhensif
French: understanding, sympathetic, accommodating. English: complete, thorough, covering all aspects.
Before: "The manager was comprehensive about the delays." (meaning: the manager was understanding)
After: "The manager was understanding about the delays."
Deception / Déception
French: disappointment. English: the act of deceiving someone, a lie or fraud.
Before: "I felt a lot of deception when the project was cancelled." (meaning: I was very disappointed)
After: "I was very disappointed when the project was cancelled."
Pretend / Prétendre
French: to claim, to allege. English: to act as if something is true when it is not; to make believe.
Before: "I pretend that this is the most efficient solution." (meaning: I claim this is the most efficient solution)
After: "I believe this is the most efficient solution." or "I would argue this is the most efficient solution."
Ignore / Ignorer
French: to not know. English: to deliberately pay no attention to.
Before: "I ignore how the system works." (meaning: I don't know how it works)
After: "I'm not familiar with how the system works." or "I don't know how the system works."
The Pattern Behind the Pattern
Most French-English false friends follow one of two patterns:
The word exists in both languages with different primary meanings. (éventuellement/eventually, actuellement/actually, sensible/sensible)
The English word exists but has a narrower or stronger meaning than the French equivalent. (demande/demand, ignorer/ignore, prétendre/pretend)
In both cases, the risk is the same: you write a grammatically correct English sentence that conveys the wrong meaning. Your reader understands the English meaning and proceeds accordingly. Neither party knows a misunderstanding has occurred.
The Structural Transfer Patterns
Beyond vocabulary, French professional writing has structural habits that transfer into English:
- Long, subordinate-clause-heavy sentences. French written style prizes rhetorical complexity. Business English prefers shorter, clearer sentences.
- The subjunctive mood. French uses it widely; English uses it rarely and many native speakers avoid it entirely. "It is important that you be present" is correct English but sounds overformal. "We need you there" is more natural.
- Inversion for emphasis. French uses inversion more freely than English. Excessive inversion reads as poetic rather than professional.
How Local Tone Handles This
Local Tone identifies false-friend substitutions and structural patterns common in French-influenced professional English. When you select a European audience or Global English, the analysis flags vocabulary that reads correctly in English but appears to be used with a French primary meaning, and suggests the correct English equivalent.

Quick Reference: French-English False Friends at Work
| Original phrasing | How a native reader interprets it | Improved version |
|---|---|---|
| "I will eventually send the revised proposal." (meaning: possibly) | The writer will send it at some unspecified future time — possibly weeks away. | "I may be able to send the revised proposal." or "I'll send it once I confirm the figures." |
| "I ignore the client's budget constraints." (meaning: I don't know them) | The writer is deliberately disregarding the client's budget. | "I'm not aware of the client's budget constraints." |
| "The manager was very comprehensive when the deadline slipped." (meaning: understanding) | The manager produced a thorough response — possibly an audit or detailed report. | "The manager was very understanding when the deadline slipped." |
| "I felt a lot of deception when I was not selected." (meaning: disappointment) | The writer believes they were lied to or deceived. | "I was very disappointed not to be selected." |
| "I pretend this approach is more scalable." (meaning: I maintain/claim) | The writer is acting as if the approach is scalable, but does not actually believe it. | "I believe this approach is more scalable." or "I would argue this approach scales better." |
| "I have a demand to discuss with you." (meaning: a request) | The writer is about to make a strong, assertive claim or ultimatum. | "I have a request." or "There's something I'd like to discuss with you." |
In Practice
Camille relocated from Paris to Sydney to join the Australian office of a French logistics company. Her English was strong — she had been writing client-facing reports in English for three years in Paris. In her first month in Sydney, she sent an internal planning email that included the line: "I ignore the exact capacity of the Brisbane depot, but I can eventually confirm this once I speak to the operations team."
Her Australian colleague read the sentence and was confused: why would Camille deliberately ignore the depot capacity, and why was confirmation so far off? He wrote back asking whether there was a problem with the data. Camille did not understand the question and assumed there had been a miscommunication about the timeline.
When a bilingual colleague reviewed the exchange, the false friends were immediately clear: Camille had used "ignore" to mean "I don't know" (ignorer) and "eventually" to mean "possibly" (éventuellement). Her intended meaning — "I'm not sure of the exact capacity but I may be able to confirm this after speaking to the operations team" — was straightforward. The misreading had generated two unnecessary follow-up emails and a small amount of confusion that took a week to fully resolve. After that, Camille kept a personal list of the ten false friends most likely to appear in her typical work writing, and checked against it before sending any external or cross-team communication.
How to Self-Check Before You Send
- Scan your email for the words "eventually," "actually," "currently," and "demand." For each one, ask whether you are using the English meaning or the French one. "Currently" (English: at this moment) is almost always the correct replacement for "actuellement."
- Check any sentence where you have used "ignore" — if you mean "I don't know," replace it with "I am not aware of," "I don't know," or "I'm unfamiliar with."
- Look for "pretend" — if you mean "claim" or "maintain" or "assert," replace it. English "pretend" implies deliberate fiction.
- If you have described someone as "comprehensive" or "sensible" in a context involving emotions or reactions, double-check: "comprehensive" means thorough, not empathetic; "sensible" means reasonable, not sensitive.
- Check "deception" and "deceive" — if you mean disappointment, replace with "disappointed" or "let down." Using "deception" to mean disappointment implies fraud or dishonesty, which is a serious misread in a professional context.
- Read your longest sentence. If it contains more than two subordinate clauses, break it into two sentences. French rhetorical style prizes complex sentence construction; English business writing does not.
Frequently Asked Questions
How do I know if a word I'm using is a false friend, if the sentence sounds correct to me?
This is the core difficulty. Because false friends produce grammatically correct sentences, they do not trigger the internal alarm that a spelling mistake or grammatical error would. The most reliable approach is to keep a personal list of the false friends specific to your writing — the ones you have already caught yourself using incorrectly. Over time, the list shrinks as the correct English meaning becomes automatic. For new words, the test is to look up the English definition explicitly, not to rely on recognition. If the English definition matches what you intend, the word is fine. If it does not, find the English word that does match your meaning.
Are there false friends that go in the other direction — English words that French speakers use correctly in English, but that trip up English speakers writing in French?
Yes, though this article is focused on French speakers writing in English. The most common reverse false friends include "sensible" (English: reasonable; French: sensitive), "location" (English: a place; French: a rental), and "large" (English: big; French: wide). If you are writing in French for a French-speaking audience, these are worth checking in the same way. The principle is the same regardless of direction: shared vocabulary between closely related languages creates false confidence.
Does it help to have an English-speaking colleague review my emails before they go out?
It helps initially, but it creates a dependency and, more importantly, it does not tell you which specific patterns you are using incorrectly. A colleague will fix the error in that one email; they will not explain why it was wrong in a way that prevents the same error in the next email. The more useful approach is to develop a self-review habit with a specific checklist — which is why the list of false friends in this article is framed around concrete checks rather than general awareness. Awareness of false friends does not help much unless it is attached to a specific habit of checking before you send.
