Why do German numbers reverse the units and tens (e.g. 24 = vierundzwanzig)?

In German, all numbers between 21 and 99 follow the "units-first" rule: you pronounce the unit digit first, add the connector word "und" (and), followed by the decade. For example, 24 is spoken as "vierundzwanzig" (four-and-twenty), and 95 is "fünfundneunzig" (five-and-ninety). This was also common in Old English ("four and twenty blackbirds").

Why is 16 "sechzehn" instead of "sechszehn"?

For ease of pronunciation, the number 6 (sechs) drops its final "s" when forming 16 (sechzehn) and 60 (sechzig). Similarly, the number 7 (sieben) drops its "en" ending when forming 17 (siebzehn) and 70 (siebzig).

Why does 30 use "dreißig" with an ß instead of "dreizig"?

30 is the only German decade that ends in -ßig (dreißig) rather than -zig (zwanzig, vierzig, fünfzig, sechzig, siebzig, achtzig, neunzig). This is an etymological preservation of the historical long diphthong.

How are large German numbers like 1984 written out in words?

In German orthography, all numbers under 1,000,000 are written as a single, unbroken compound word without spaces or hyphens. For example, 1984 is written as "eintausendneunhundertvierundachtzig". Only millions and billions are separated into distinct capitalized nouns (e.g. "eine Million zweihunderttausend").

What is the difference between eins and ein in German numbers?

"Eins" is used when counting alone (eins, zwei, drei) or at the very end of a number (e.g. einhunderteins). In compound numbers before "und" or "hundert/tausend", the final "s" is dropped to become "ein" (e.g. einundzwanzig, einhundert, eintausend).

How do decimals and commas work in German numbers?

German reverses the English convention for periods and commas: in German, a comma (,) is used as the decimal separator (e.g. €12,50 = 12.50 Euros), while periods (.) or non-breaking spaces are used to group thousands (e.g. 1.000.000 = One Million).

How do German ordinal numbers work (1st, 2nd, 3rd)?

For numbers 1 to 19, add the suffix -te (e.g. der vierte = the 4th), with irregular forms for 1st (erste), 3rd (dritte), 7th (siebte), and 8th (achte). For numbers 20 and higher, add the suffix -ste (e.g. der zwanzigste = the 20th, der hundertste = the 100th). In writing, German uses a period after the number: 1. Mai = 1st of May.

The Complete Guide to German Numbers: The Units-First Rule & Spelling Secrets

Counting in German (Zählen auf Deutsch) is logical, structured, and predictable once you master a single core concept: the units-first reverse rule. In German, two-digit numbers from 21 to 99 are spoken with the single digit first, followed by the connector word und (and), and finally the decade.

For example, the number 25 is not "twenty-five" — it is fünfundzwanzig (literally, five-and-twenty). Once you learn the basic units (0–9) and decades (10–90), you can instantly construct any number in the German language up to one million.

1. The Reverse Rule (21–99)

Always format as [Units] + und + [Decade]. Example: 48 = achtundvierzig (eight-and-forty). 93 = dreiundneunzig (three-and-ninety).

2. The Dropped S & EN Traps

eins becomes ein (einundzwanzig). sechs drops "s" (sechzehn, sechzig). sieben drops "en" (siebzehn, siebzig).

3. One Giant Unbroken Word

Numbers under 1 million are written as a single compound word without spaces: siebenhundertachtundfünfzig (758). Only millions are capitalized nouns (eine Million).

German Punctuation Rules: Commas vs. Periods in Numbers

When traveling, banking, or shopping in Germany, Austria, or Switzerland, note that punctuation marks for numbers are the exact reverse of the US/UK system:

Decimal Separator = Comma (,)

English: $19.99 ➔ German: 19,99 € (neunzehn Euro neunundneunzig).

Thousands Separator = Period (.)

English: 1,500,000 ➔ German: 1.500.000 (eine Million fünfhunderttausend).
