German support

SarahMarkus, good afternoon. I've been through your draft slides for the London investors, and I'd like to double-check one figure before anything goes out.Ich möchte eine Zahl gegenprüfen, bevor etwas rausgeht.

MarkusOf course. Which one?

SarahSlide four. It says the global market is worth one point four billion euros. But your own revenue slide shows eight hundred million for your division alone. One of those numbers has to be wrong.

MarkusThat figure comes straight from our German market report. It says eine Komma vier Billionen Euro — so, one point four billion. Billion is billion, isn't it?

SarahAh, there it is — the classic false friend. In English, the German Billion is a trillion, a million millions. And your Milliarde is our billion. The words look identical, but they're three orders of magnitude apart.Die Wörter sehen identisch aus, liegen aber drei Größenordnungen auseinander.

MarkusSo slide four should say one point four trillion. Which means I nearly presented our market as a thousand times smaller than it is. In front of investors.

SarahYou wouldn't be the first, believe me. A typo looks careless; a misleading figure looks like you don't understand your own market. That's why we always double-check numbers before investors sign off on anything.Ein Tippfehler wirkt schlampig; eine irreführende Zahl wirkt, als verstünden Sie Ihren eigenen Markt nicht.

MarkusUnderstood. I'll correct slide four tonight. Is there anything else in the numbers I should look at?

SarahOne small thing: in the pricing table you wrote two comma five per cent, with a comma. English uses a decimal point — two point five per cent. And commas separate thousands, so ten thousand is one-zero-comma-zero-zero-zero.Im Englischen steht der Dezimalpunkt, das Komma trennt Tausender.

MarkusNoted — decimal point, not comma. Is there a rule of thumb for the big numbers, so this doesn't happen again?

SarahMy rule of thumb: whenever an English word looks exactly like a German word, slow down and check it. And with large figures, say them out loud in millions — a trillion is a million millions, a billion is a thousand millions. If the sentence sounds absurd, the translation is wrong.Mein Grundsatz: Wenn ein englisches Wort genauso aussieht wie ein deutsches, langsamer werden und prüfen.

MarkusThat would have caught it immediately. I'll send you the revised deck by six — could you give it a second pair of eyes before it goes to the investors?

SarahHappy to. Send it over, and well done for checking now rather than on stage in London.

Language notes

In this episode a London investment partner spots a market figure that is off by a factor of one thousand on German pitch slides — caused by the Billion/Milliarde false friend. You learn the English words for large numbers, the decimal-point rule and eight phrases for politely correcting figures (level B2).

Billion, Milliarde, trillion: the system behind it

The German Milliarde (10⁹) is the English billion; the German Billion (10¹²) is the English trillion. The historical "milliard" no longer exists in modern English. Sarah's sanity check is the best protection: say the number out loud in millions ("a billion is a thousand millions"). If the sentence sounds absurd, the translation is wrong — which is exactly how Markus's error surfaces, since a 1.4-billion market would be smaller than his own division's revenue.

Correcting numbers politely

Sarah never says "That's wrong". She places the numbers side by side ("One of those numbers has to be wrong") and lets Markus draw the conclusion himself. This pattern — evidence instead of verdict — is the standard way to raise a partner's mistake in English business culture. Useful openers: "I'd like to double-check one figure", "Could we look at slide four together?", "Something doesn't quite add up".

Decimal points and thousands separators

In English, comma and point are exactly reversed: 2,5 % becomes 2.5 per cent, and 10.000 becomes 10,000. In Excel exports and price tables this is the most common error source for German teams. Before any English offer, check three things: large number words (billion/trillion), decimal marks and currency position ($1.4m, not 1,4 m$). A second pair of eyes from a native English speaker remains the safest control.

Frequently asked questions

What language level is this episode for?

Level B2 (CEFR). The dialogue uses upper-intermediate business English from finance and pitch situations; all eight key phrases are explained bilingually.

What is the difference between Billion and billion?

The English billion is the German Milliarde (10⁹). The German Billion is the English trillion (10¹²). Confusing them puts you off by a factor of one thousand — an expensive mistake in offers, pitches and contracts.

How do I politely correct a partner's figure?

With evidence instead of a verdict: open with "I'd like to double-check one figure", then place both numbers side by side ("One of those numbers has to be wrong") and let your partner draw the conclusion — as Sarah does in this episode.
