In German, the numbers for the tens from 20 to 90 follow a regular pattern and are essential for counting, telling time, shopping, and more. They are:
  • 20: zwanzig
  • 30: dreißig
  • 40: vierzig
  • 50: fünfzig
  • 60: sechzig
  • 70: siebzig
  • 80: achtzig
  • 90: neunzig
Each number beyond 20 ends with "-zig," which is similar to the English "-ty." Notably, 30 (dreißig) uses a special spelling with "ß," and some roots are slightly modified for ease of pronunciation (e.g., sechs → sech-, sieben → sieb-).
  • German tens: 20=zwanzig, 30=dreißig, 40=vierzig, 50=fünfzig, 60=sechzig, 70=siebzig, 80=achtzig, 90=neunzig
  • Use "-zig" for most tens; 30 is "dreißig" with a special "ß"
  • Minor root changes for 60 (sechzig) and 70 (siebzig)
The correct German tens are: zwanzig, dreißig, vierzig, fünfzig, sechzig, siebzig, achtzig, neunzig.

Structure & Usage

From 20 on, German numbers use a regular system. Only 10, 11, and 12 have unique forms; after that, you combine roots and endings logically. This makes it easy to extend beyond 90 (e.g., 100 = hundert).
  • All tens except 10 start with a number root + "-zig" (or "-ßig" for 30)
  • Between 21-99, use a reverse order with "und" for units (e.g., 21 = einundzwanzig)
The pattern is number root + "-zig" for 20-90, with some exceptions.

Exercises

  1. List the German words for the tens 20, 40, 60, and 80.
  2. Identify the pattern in the German tens and explain how you would guess the word for 100 (hundred) based on it.
  3. Compare the German tens to English. What similarities and differences do you notice?
zwanzig, dreißig, vierzig, fünfzig, sechzig, siebzig, achtzig, neunzig
They use number roots plus '-zig' (with some exceptions).
20, 30, 60, and 70 are special: zwanzig, dreißig, sechzig, siebzig.

Conclusion

German tens follow a mostly regular pattern with some unique forms for 20, 30, 60, and 70.
  • Tens are: zwanzig, dreißig, vierzig, fünfzig, sechzig, siebzig, achtzig, neunzig
  • Use number root + "-zig," except for special cases
  • Knowing this pattern helps you understand and predict numbers in German
