False Friends in Business English: The Words That Cost Money

1Why business English is where false friends actually cost something

In a language class, a false friend produces a laugh. In a quarterly report, it produces a wrong number. The vocabulary is the same; the consequences are not, and that changes which words are worth studying.

The pattern is specific and it is not random. Business vocabulary is overwhelmingly Latin and French in origin, which means most European languages have the same word. Shared origin is exactly the condition that produces false friends: the word travelled into both languages and then drifted, so it looks identical and means something adjacent. Everyday Anglo-Saxon words like get, put and make have no cousins in Spanish or German, so they produce no false friends at all.

The rule this produces is uncomfortable but reliable: the more formal and professional your English vocabulary, the higher your false friend density. A learner speaking simply is safer than a learner using the impressive-sounding Latin word, because the impressive-sounding word is the one that also exists in their language.

What the errors actually cost

Three levels. A tone error, where demand or control makes you sound aggressive, costs goodwill and you never find out. A commitment error, where eventually or compromise says the opposite of what you meant, costs a misaligned expectation and eventually an argument. A number error, where Billion or a decimal comma is misread, costs money directly and is the only one anybody notices in time.

This guide covers the false friends that survive into professional English from the languages that produce most of them: German, French, Spanish, Italian, Portuguese and Russian, plus the business-English conventions that travel from Indian and East Asian offices. Where a word is a problem in only one language, it is marked.

Tip: Read section three first if you work with numbers, and section six first if most of your English is email. Those two sections cover the errors that are both most common and most expensive.

2The six that appear in almost every language

These six are false friends in German, French, Spanish, Italian, Portuguese and Russian simultaneously, because all six languages inherited the Latin word and English drifted away from it. If you fix nothing else, fix these.

actual does not mean current

German aktuell, French actuel, Spanish actual, Italian attuale, Portuguese atual and Russian aktualny all mean current or up to date. English actual means real, as opposed to imagined or estimated, and actually means in fact. So the actual figures means the real figures, not this month's figures. Say current, latest, or up to date.

eventually does not mean possibly

German eventuell, French eventuellement, Spanish eventualmente and Italian eventualmente all mean possibly or if necessary. English eventually means in the end, after some delay, and it is certain rather than conditional. We will eventually sign the contract promises that you will sign. If you meant possibly, say possibly, or if necessary, or we may. This one reverses the meaning of a commitment, which makes it the most dangerous of the six.

sensible does not mean sensitive

French sensible, Spanish sensible, Italian sensibile and Portuguese sensivel mean sensitive. English sensible means practical and reasonable. This matters most in one phrase: sensible data should always be sensitive data. Writing that a system handles sensible information tells a compliance auditor nothing about whether it handles personal data.

assist does not mean attend

French assister a, Spanish asistir a and Italian assistere a mean to attend an event. English assist means to help. I will assist the meeting says you will help the meeting, which is not a thing. Say I will attend the meeting, or simply I will be there.

demand does not mean ask

French demander and Spanish demandar mean simply to ask. English demand is forceful: it means to insist, and it presumes a right. I demand a meeting with your director is an escalation, and to a native English speaker it reads as the sentence before a complaint. Say I would like to request, or could we arrange.

pretend does not mean intend

Spanish pretender, French pretendre and Portuguese pretender mean to intend, to aim, or to claim. English pretend means to act as if something is true when it is not. We pretend to expand into Canada next year tells the reader you are faking an expansion. Say we intend, or we plan.

Of these six, eventually and pretend are the two that say the opposite of what you meant rather than something merely odd. Both appear most often in exactly the sentences where precision matters: timelines and plans.

Tip: Write these six on a card and keep it visible while you write English email for a month. They are frequent enough that a month of deliberate checking is usually enough to break the habit permanently.

3Billion, milliard and the decimal comma

This section is short and it is the most expensive one in the guide. Numbers are the only false friends where the error is unambiguous, verifiable, and directly financial.

A German Billion is an English trillion

Continental Europe historically used the long scale, in which a Billion is a million million. English uses the short scale, in which a billion is a thousand million. So German Billion, French billion and Spanish billon all equal English trillion, and they are a thousand times larger than English billion. In a financial document this is not a nuance; it is a factor of one thousand.

Milliard is the word English does not have

German Milliarde, French milliard, Spanish millardo and Russian milliard all mean a thousand million, which is exactly what English calls a billion. English abandoned milliard decades ago and most speakers have never heard it. So the safe conversion is: your Milliarde is their billion, and your Billion is their trillion.

The comma and the period swap roles

Most of continental Europe and Latin America writes 1.000.000 for a million and 12,5 for twelve point five. English writes 1,000,000 and 12.5. The characters are the same and their jobs are opposite. A price written 1.250 means one thousand two hundred and fifty in Germany and one point two five in an English contract.

Dates on invoices

Most of the world writes day first, so 03/11/2026 is the third of November. The United States writes month first, so the same string is the third of March. Canada uses both and its government forms prefer year first. On anything that crosses a border, write the month as a word: 3 November 2026. There is no numeric format that is safe everywhere.

The rule for any document that leaves your country: spell out large numbers in words next to the figure, write the currency code rather than a symbol, and write the month as a word. USD 1.5 million, not 1.500.000. This costs eight characters and removes the entire class of error.

This is the only section in this guide where the error is silent and total. Nobody misreads a wrong verb; everybody misreads a wrong decimal separator, because the number still looks like a number.

Tip: Set your spreadsheet locale to English when you produce anything for an English-speaking counterparty. Locale settings fix this at the source, which no amount of proofreading reliably does.

4The business false friend list, by source language

Grouped by the language that produces them. Find your own language first, then read the others, because you will meet colleagues who make those errors and it helps to know what they meant.

Fabrik is a factory, not a fabric; fabric is cloth. This one appears constantly in manufacturing.
Provision is a sales commission; English provision means a supply, or a clause in a contract.
Konzern is a corporate group; English concern means a worry, or vaguely a business.
Prospekt is a brochure; English prospect is a potential customer.
Termin is an appointment; English term is a period of time or a condition.
Kontrolle is a check or inspection; English control means power over something.
Chef is a boss; English chef cooks.
Personal means staff; English personnel is the correct word and personal means private.
Rente is a pension; English rent is what you pay for property.
Konkurrenz is competition; English concurrence means agreement.
bekommen means to receive; English become means to turn into. I will become the contract is the classic version.
Etikett is a label; English etiquette is manners.
Mappe is a folder; English map shows geography.
Gift means poison, which makes an English gift certificate briefly alarming.

Spanish carpeta and Italian cartella are a folder; English carpet is on the floor.
Spanish exito and Italian esito relate to success; English exit is a way out. Our product was a great exit means you sold the company.
Spanish compromiso and Portuguese compromisso mean a commitment; English compromise means a concession where both sides give something up. We have a compromise with the client says the opposite of what you meant.
Spanish soportar and French supporter mean to tolerate; English support means to help or endorse. I cannot support this proposal means you oppose it, which may be exactly wrong.
Spanish realizar and French realiser mean to carry out; English realise mostly means to become aware. We realised the payment should be we processed the payment.
French and Spanish agenda is a diary or appointment book; English agenda is the list of topics for a meeting.
French conference is often a lecture; English conference is a multi-day event with many speakers.
French formation is training; English formation is the act of forming something.
French deception means disappointment; English deception means deliberate lying. This is a serious one in a performance review.
French preservatif and Spanish preservativo mean a condom; English preservative is a food additive. Every food exporter learns this once.
Spanish injuria means an insult; English injury is physical harm.
Spanish sensible covered above, and Spanish sano means healthy while English sane means mentally well.
Italian and Spanish attualmente means currently; English actually means in fact.
Portuguese pretender means to intend, covered above.

aktualny means current or relevant, not actual.
magazin is a shop, not a magazine.
kabinet is an office, not a cabinet.
dekada means ten days in technical Russian, not ten years.
fabrika is a factory, not a fabric.
aktsiya is a promotion or a share, and English action is neither.
prospekt is an avenue or a brochure, not a prospect.
konkurs is a competition or a tender, and English concourse is a hall.

Tip: Do not read your own language's list looking for words you get wrong. Read it looking for words you use often. Frequency times error rate is what actually costs you, and a word you use weekly matters more than a word you have never needed.

5Job titles that do not translate

Titles are the false friends most likely to appear on a CV, which makes them the ones most likely to be read by someone deciding about you. They are also the ones people are least likely to check, because a title feels like a fact rather than a translation.

Director and manager are not the same rank everywhere

In much of continental Europe, Latin America and the Middle East, the word translated as director covers what English calls a manager. In English-speaking corporate structures, Director is a senior rank above Manager, and in the United Kingdom a Director may be a legal officer of the company with statutory duties. Translating your title upward is not ambition; it is a claim an interviewer will check.

Engineer is a protected title in Canada

In many countries, Engineer is an academic title used by anyone with the degree, and it is often used as a form of address. In Canada, Engineer and the designation P.Eng are legally protected and restricted to people licensed by a provincial regulator. Describing yourself as an engineer on a Canadian CV without a licence is a regulatory issue, not a style choice. The accurate alternatives are engineering graduate, software developer, or the specific role you held.

Collaborator means something you do not want it to mean

French collaborateur and Italian collaboratore mean employee or colleague, and are entirely neutral. English collaborator carries a strong secondary meaning from the Second World War: someone who cooperated with an occupying enemy. Our five hundred collaborators is a sentence English speakers read twice. Say employees, staff, team members, or colleagues.

Cadre reads as military or political in English

French cadre and its equivalents mean a manager or a professional-grade employee, and in some administrations simply an official. English cadre is rare and sounds either military or party-political. Say manager, senior staff, or professional depending on what you mean.

Chef is a boss in German and a cook in English; the English word for the role is manager or head of department
Assistant is genuinely junior in English, so an assistente or Assistent who is actually a specialist should use associate or specialist
Responsible, as in responsable in French and responsable in Spanish, is used as a noun meaning the person in charge; English responsible is only an adjective, so say the person responsible or the lead
Consulter is not an English noun; the word is consultant
Controller is a real English job title in finance, so this one transfers, but Controlling as a department name does not; English says financial control or management accounting
Doctor as a courtesy title for anyone with a doctorate is normal in Germany and Italy and unusual in English-speaking business, where it usually signals a medical doctor or an academic
Vice-President means very different things in American, British and European companies, and on an American CV it is often a mid-level bank title rather than an executive one

If your CV crosses a border, translate your title by its responsibilities rather than by its words. Write the closest English rank and add one line describing what you actually did and how many people reported to you. That is unambiguous and it cannot be read as inflation.

Tip: Search your target title on job listings in the country you are applying to and read three descriptions. If your actual responsibilities do not match those descriptions, you have the wrong translation, however literally correct it is.

6Email formulas that are false friends of politeness

These are not word errors. Every word is real English and the grammar is fine. They are false friends of register: they carry a level of politeness in one variety of English and a different signal in another, and the signal is usually unintended.

Kindly revert means please reply in Indian and Middle Eastern business English. To a British or North American reader, revert means to go back to a previous state, so the sentence reads as an instruction to undo something. Say please reply, or let me know.
Do the needful is standard in Indian English and clear to hundreds of millions of speakers, but a Canadian or American reader has usually never met it. Say please take care of it, or name the action.
Please kindly is redundant in English, since both words do the same job. One or the other, never both.
As per your request sounds legalistic and dated to most native readers; as you asked or following your request is normal.
Please find herewith attached is a form nobody has used since the fax machine; say I have attached, or here is.
Dear Sir or Madam is now dated and slightly cold in North America; use the person's name, or Hello, or if you truly have no name, Dear Hiring Manager.
I am writing to inform you that is correct but heavy; in most email it can simply be deleted.
Thanks in advance is read as mild pressure by many native speakers, because it thanks someone for a thing they have not agreed to; say thank you for considering it, or thank you at the end instead.
Send me the file is a neutral request in German, Russian and several other languages, where politeness lives in the verb form; in English the bare imperative is an order. Add could you, or when you get a chance.
Mit freundlichen Gruessen and its equivalents are more formal than anything routine in English email; Best regards is the safe universal default, and Best alone is normal, not curt.
Looking forward to hear from you is a very common error; the correct form is looking forward to hearing from you, because forward to takes a gerund.
I remain at your disposal is a direct translation from French and Italian that sounds subservient in English; say let me know if you need anything else.

Notice the underlying pattern. Languages carry politeness in different places: in verb forms, in pronouns, in particles, or in vocabulary. English carries almost all of it in modal verbs and hedges. So when you translate a polite sentence from a language that carries politeness elsewhere, the politeness has nowhere to land and it disappears, leaving a sentence that is accurate and blunt.

Tip: Learn five English hedges and use them until they are automatic: could you, would you mind, when you get a chance, I was wondering if, and if it is not too much trouble. Those five cover almost every request you will ever make in English, and they carry the politeness your own language put somewhere else.

7Words that sound like an accusation in English

A separate category worth its own section, because the cost is invisible. In each case the speaker means something neutral and the listener hears something hostile, and nobody ever mentions it.

control, from German Kontrolle and French controler, means to check or verify in those languages; in English it means to hold power over someone. We will control your invoices sounds like surveillance. Say we will check, or review.
demand, covered above, presumes a right in English. Say request.
exploit, from French exploiter and Spanish explotar, means to operate or make use of a resource, and is neutral; English exploit strongly implies unfair treatment of people. Say operate, or make use of.
deception, from French deception, means disappointment; English deception means deliberate lying. In a performance review this is the difference between I was disappointed and I was lied to.
pretend, covered above, means to fake in English. Say intend.
manipulate, from Romance languages, can neutrally mean to handle or operate equipment; in English applied to people it means psychological abuse. Say handle, or operate.
delay used as a verb by a French speaker translating delai can mean deadline; English delay always means lateness. Say deadline or timeframe.
criticism, from Romance and German usage, is often neutral and means analysis; English criticism is negative unless you say constructive criticism explicitly.
obligate and obligatory are stronger in English than their equivalents; where French says obligatoire routinely, English often prefers required.
eventual, as an adjective, means final in English and possible in French and Spanish; an eventual partner in English is the one you end up with, not a candidate.

The cost of this category is entirely hidden. Nobody replies to say your email sounded aggressive. They simply become slightly more formal, or slower, or they route the next question to someone else. If you have ever wondered why a relationship cooled without an incident, this list is worth reading twice.

Tip: When you catch yourself reaching for an impressive Latin word in a tense conversation, use the plain Anglo-Saxon one instead. Check beats control, ask beats demand, use beats exploit. Plain words are almost never the ones that carry an unintended accusation.

8Meeting vocabulary

Words that appear in almost every meeting and mean something adjacent in most European languages.

agenda in English is the list of topics for a meeting; in French, Spanish, Italian and German it is your personal diary. Let me check my agenda should be let me check my calendar.
conference in English is a large multi-day event; French conference and Spanish conferencia often mean a single lecture. For a phone meeting, English says call or conference call, never a conference.
Termin in German is an appointment; English has no cognate, so say appointment, meeting, or slot.
actual in the sense of current, covered above, appears in nearly every status update. Say current.
formation in French is training; English training or onboarding is what you want.
animate, from French animer une reunion, means to chair or facilitate; English animate means to bring to life or to make a cartoon. Say chair, run, or facilitate.
assist, covered above, means help. Attend is the word for being present.
deliberate, from Romance usage, can mean to discuss; in English deliberate as a verb is formal and legal, so say discuss.
propose is fine, but the construction is not: English says I propose that we move the date, never I propose you to move the date.
resume, from French resumer, means to summarise; English resume means to start again after a pause, and a resume with accents is a CV. Say summarise.
eventually in a status update, covered above, promises certainty. If you mean it might happen, say it might.
assist at, attend to, discuss about and enter to are the four most common preposition errors in meetings; the correct forms are attend, deal with, discuss, and enter.

Tip: The four preposition errors at the end of that list are worth separate drilling, because they survive to a very high level. Discuss, enter, attend and phone all take a direct object in English with no preposition at all.

9Contract and finance words where being wrong is expensive

The highest-stakes group. In each case both languages have the word, both meanings are plausible in context, and the difference is money.

provision in English is a clause in a contract, or a supply of something; German Provision is a sales commission. A contract discussing provisions and one discussing commissions are different documents.
compromise in English is a settlement where both sides concede; Spanish compromiso and Portuguese compromisso mean a firm commitment. Confirming a compromise when you meant a commitment weakens your own position in writing.
engage in English means to hire, to occupy, or to enter into; French s'engager means to commit oneself. We are engaged to deliver in March is ambiguous where committed to deliver is not.
deposit in English is money paid up front and usually returnable; in several languages the equivalent means a down payment that is not returnable. Say deposit, refundable, or non-refundable deposit explicitly.
credit in English is money lent to you; in some languages the cognate is used for the loan itself and in others for the balance in your favour. In a statement, always say balance or loan rather than credit.
balance in English is what remains in an account; French balance is a weighing scale and Spanish balance is a balance sheet. Say account balance, or balance sheet, never balance alone across languages.
exit in English is a way out, or in venture finance the sale of a company; Spanish exito means success. These meet in exactly the sentences where you are describing an outcome.
actual costs in English means real costs as opposed to budgeted; in most European languages the same phrase means current costs. In a budget review these are two different columns.
eventual payment in English means the payment that finally happens; in French and Spanish it means the payment that might happen. On an invoice this is a serious difference.
receipt in English is proof of payment; several languages have a cognate meaning a recipe or a prescription. If you mean the document proving payment, say receipt, and if you mean receiving money, say receipts as a plural or revenue.
assurance in English is a promise or confidence; French assurance is insurance. Say insurance policy explicitly.
estate in English is property or a deceased person's assets; Spanish estado and French etat mean state or condition. Real estate is a fixed phrase and does not mean the state of the property.

If a document is legally binding, do not translate the term at all. Use the English term the counterparty's own contract uses, and if you are not certain what it means in their jurisdiction, ask. Every professional in a cross-border deal has had to ask this question, and asking has never cost anyone a deal.

Tip: Keep a two-column glossary for the counterparty you work with most, with their term on the left and the English term used in the signed contract on the right. Ten entries will cover almost everything, and the list stops being needed within a year.

10What to do when you are unsure mid-meeting

Everything above assumes you have time to check. In a live meeting you do not, so this section is about what to do in the four seconds you actually have.

Reach for the plain word

If you are about to use an impressive Latin word and you are not certain, the plain Anglo-Saxon alternative is almost always safe, because plain English words rarely have cousins in other languages and therefore rarely have false friends. Check rather than control, ask rather than demand, use rather than exploit, plan rather than pretend, current rather than actual.

Say numbers twice, in two forms

One point five million, that is one five zero zero zero zero zero. This sounds fussy for exactly two seconds and then everyone relaxes, because everyone in an international meeting has been burned by a number. Nobody has ever objected to a number being confirmed.

Repair without apologising

Sorry, I mean current, not actual, is a complete repair and it takes one second. Do not explain the false friend, do not apologise twice, and do not switch to your own language to fix it. Native speakers repair themselves constantly and nobody registers it as a mistake.

Confirm commitments in writing, in short sentences

Most of the expensive errors in this guide involve commitment: eventually, compromise, engage, pretend. All four become harmless the moment they are written down in a short follow-up, because the reader has time to notice the oddity and ask. Send the one-paragraph summary; it is the single most effective protection against everything in this guide.

Ask what the word means, in English

What do you mean by provision, the contract clause or the commission is a normal professional question, and asking it marks you as careful rather than weak. The alternative is discovering the answer later, in writing, with money attached.

Tip: Choose in advance which three words you will slow down for. For most people they are the number words, the commitment words, and the one false friend they know they personally get wrong. Three is a list you can hold in your head under pressure; twenty is not.

11Twelve sentences to correct

Each contains one error from this guide. Try each before reading the correction.

Please send me the actual figures for this quarter. Correction: Please send me the current figures for this quarter. Actual means real, not up to date.
We will eventually sign the agreement in March. Correction: We may sign the agreement in March, if that is what you meant. Eventually promises it will happen.
The system stores sensible customer data. Correction: The system stores sensitive customer data.
I will assist the board meeting on Tuesday. Correction: I will attend the board meeting on Tuesday.
Our company has five hundred collaborators. Correction: Our company has five hundred employees.
The budget is 1.500.000 euros. Correction: The budget is 1,500,000 euros, or better, EUR 1.5 million.
We have a compromise with the supplier until December. Correction: We have a commitment with the supplier until December.
I demand a meeting with the project director. Correction: I would like to request a meeting with the project lead.
We will control your invoices before payment. Correction: We will check your invoices before payment.
Kindly revert with your feedback by Friday. Correction: Please reply with your feedback by Friday.
I am looking forward to hear from you. Correction: I am looking forward to hearing from you.
We pretend to open two new offices next year. Correction: We plan to open two new offices next year.

Tip: Score yourself, then pick only the ones you got wrong. Twelve corrections read once change nothing; three corrections drilled for a week change how you write.

12Building your own business false friend list

A published list is a starting point. The list that actually helps you is the one built from your own writing, in your own industry, because industry vocabulary is Latin at a much higher rate than everyday language and therefore produces far more false friends.

Where to look

Use real documents you produced: sent email, a report, a proposal, a CV, a slide deck. Not exercises. False friends only appear when you were concentrating on the content rather than the language, which is precisely what an exercise prevents.

The test that works

For every word longer than about seven letters that also exists in your language, search the English word alone and read three real English sentences using it. If none of those three sentences could contain your sentence, you have found a false friend. This works because false friends fail on the company a word keeps before they fail on its dictionary definition.

Take three real documents you wrote in English in the last month
Highlight every word that also exists in your own language, which in business English will be a lot of them
For each, search the English word and read three sentences from native business sources
Mark it wrong if your sentence does not fit the pattern of those three
Write the correction as a full sentence from your own work, not as a single word
Sort the confirmed errors into tone, commitment and number, because those are the three cost levels
Fix all the number ones this week, the commitment ones this month, and the tone ones gradually
Reread the list before you write anything that goes outside your company

Expect fifteen to thirty in your first three documents if you work in a Latin-derived industry vocabulary such as finance, law, pharmaceuticals or engineering, and fewer in a technical field that borrowed its vocabulary from English in the first place. The number falls quickly, because this is a finite list and not a general weakness.

Tip: The fastest way to build a feel for which word belongs where is to hear business English used rather than to read it. Podcasts and recorded interviews in your own industry give you the collocations directly, which is what false friends actually break.

Frequently asked questions

Which business false friend causes the most real damage?

By financial size, the billion and Billion mismatch, because it is a factor of one thousand and it appears in exactly the documents where large numbers matter. By frequency, actual used to mean current, which appears in almost every status update in Europe. By hidden cost, eventually, because it converts a maybe into a promise and nobody discovers the mismatch until a deadline passes.

Is Indian business English wrong?

No. Indian English is a full variety with more speakers than British English, and revert, do the needful and prepone are correct within it. The question is never whether it is wrong but whether your particular reader will understand it. Writing to a colleague in Mumbai, revert is clear. Writing to a client in Toronto, it is not. Choose by audience, not by rule.

Should I avoid Latin-derived words in English entirely?

No, but prefer the plain word when you are unsure, and especially in any sentence about commitment, money or someone's performance. Plain English is not less professional; a great deal of native business writing advice pushes in the same direction for readability reasons. The false friend benefit is a bonus.

How do I write my job title on an international CV?

Write the closest English rank, then a line describing what you actually did, including how many people reported to you and what budget you were responsible for. That combination cannot be read as inflation, and it survives translation into any market. If your national title has no English equivalent, use the responsibilities line and drop the title translation entirely.

My English is advanced. Do I still need this?

Advanced speakers make more of these errors, not fewer, for a structural reason: false friends live in exactly the formal, Latin-derived vocabulary that advanced speakers use and beginners avoid. Someone speaking simply says check and ask; someone speaking impressively says control and demand. The errors in this guide are almost all errors of confidence.

How long does it take to fix these?

The number and date conventions can be fixed in an afternoon by changing your software settings and adopting one writing rule, and they are the highest-value hour in the whole guide. The six universal false friends usually take a month of deliberate checking. Tone-level errors take longest, because nothing in your environment corrects them, which is exactly why it is worth having read them written down.
