Einundzwanzig: Why Germans Count Backwards (and Everything Else About Numbers)

German numbers up to twelve are painless. After that, German does something that trips up almost every learner at a checkout: it says the ones before the tens. Twenty-one is einundzwanzig — literally "one-and-twenty." Fifty-four is vierundfünfzig, "four-and-fifty."

Your brain wants to write the 5 first. It'll keep wanting to for about a month. This page gives you the whole system, plus the places numbers actually show up in daily life — prices, phone numbers, dates, and forms — where the conventions are different from English too.

Quick notes:

  • Eins is for counting. In front of a noun it becomes ein / eine: eins, zwei, drei, but ein Kaffee, eine Stunde.
  • On the phone and in shops, Germans often say zwo instead of zwei. It sounds less like drei over a bad line. You'll hear it in train announcements too.

Quick note: two of them lose a letter. Sechzehn drops the s from sechs, and siebzehn drops the en from sieben. The same thing happens in sechzig and siebzig.

einundzwanzig

Quick notes:

  • It's all one word. Einundzwanzig, not ein und zwanzig.
  • Ein, not eins, in front of -und-: einundzwanzig, einunddreißig.
  • The practical trick: when someone says a two-digit number, wait for the end before writing anything down. Write the second digit first, then the first. It feels backwards for a few weeks and then it doesn't.

Quick notes:

  • Above a hundred, the order goes hundreds, then the reversed two-digit part: 347 is dreihundertsiebenundvierzig — three-hundred-seven-and-forty.
  • Milliarde is the English "billion." German Billion means a trillion. This is the number that goes wrong in news translations constantly.
  • Years before 2000 are read in hundreds: 1989 is neunzehnhundertneunundachtzig. From 2000 on, just thousands: zweitausendsechsundzwanzig.

Where the Punctuation Flips

German uses the comma and the full stop the opposite way round from English.

Quick notes:

  • A comma is the decimal point; a full stop separates thousands. On a rent contract, 1.200,00 € is twelve hundred euros.
  • Prices are read without "comma": drei Euro fünfzig, never drei Komma fünf null Euro.
  • Anderthalb is a special word for one and a half. Zweieinhalb, dreieinhalb follow the regular pattern.

Quick notes:

  • Up to 19, add -te; from 20, add -ste. Dritte and siebte are the two irregulars worth watching.
  • A full stop after a number makes it an ordinal: 1. Mai is read erster Mai. Dates are written day first: 21.09.2026.
  • The days and months themselves are in days of the week and seasons and months.

Write Them the German Way

This matters on every form you fill in by hand. Germans write 1 with a long upstroke at the top, so it looks a little like a 7 without the crossbar — and they write 7 with a line through the middle so the two can't be confused. If you write a plain English "1", some Germans will read it as 7; if you write a 7 without the crossbar, some will read it as 1. On an Amt form with your date of birth, that's worth avoiding.

Three Mistakes to Avoid

Writing the digits in spoken order. Hear vierundfünfzig, write 54 — not 45. Wait for the whole number.

Translating billion as Billion. A billion is eine Milliarde. Eine Billion is a thousand times more.

Reading the comma as a thousands separator. 1,500 € on a German bill is one euro fifty, not fifteen hundred.
