Numbers 1, 20, The Foundation
These twenty numbers are your building blocks. Numbers 1-12 are unique and require memorization. Numbers 13-19 follow a simple pattern: ones digit plus zehn (ten).
Important Spelling Notes
Two numbers have special spelling rules. Sechzehn (16) drops the "s" from "sechs." Siebzehn (17) shortens "sieben" to "sieb." These patterns repeat in all higher numbers ending in 16 and 17.

Numbers 21, 100, The Reversed Pattern
Here is where German diverges from English. In compound numbers, the ones digit comes first, followed by und (and), then the tens digit. All written as one word. So 21 is einundzwanzig (one-and-twenty) and 54 is vierundfünfzig (four-and-fifty).
Understanding Tens Words
All tens words end in -zig except dreißig (30), which ends in -ßig. Notice that sechzig (60) and siebzig (70) follow the same dropping and shortening rules as 16 and 17.
Compound Number Rules
Every number from 21-99 follows this pattern without exception. Eins drops to "ein" in compounds, so 21 is "einundzwanzig," not "einsundzwanzig."
| Term | Meaning | Pronunciation | Example |
|---|---|---|---|
| einundzwanzig | 21, one-and-twenty | EYN-oont-tsvahn-tsikh | Ich bin einundzwanzig Jahre alt., I am twenty-one years old. |

| dreiundzwanzig | 23, three-and-twenty | DREY-oont-tsvahn-tsikh | Mein Geburtstag ist am dreiundzwanzigsten., My birthday is on the 23rd. |
| achtundzwanzig | 28, eight-and-twenty | AHKHT-oont-tsvahn-tsikh | Februar hat achtundzwanzig Tage., February has twenty-eight days. |
| dreißig | 30, thirty (note: -ßig, not -zig) | DREY-sikh | Ich habe dreißig Minuten Pause., I have thirty minutes of break. |
| einunddreißig | 31, one-and-thirty | EYN-oont-drey-sikh | Januar hat einunddreißig Tage., January has thirty-one days. |
| vierzig | 40, forty | FEER-tsikh | Mein Vater ist vierzig Jahre alt., My father is forty years old. |
| fünfzig | 50, fifty | FUENF-tsikh | Das kostet fünfzig Cent., That costs fifty cents. |

| neunzig | 90, ninety | NOYN-tsikh | Ich muss neunzig Seiten lesen., I have to read ninety pages. |
| hundert / einhundert | 100, one hundred | HOON-dert / EYN-hoon-dert | Das kostet hundert Euro., That costs one hundred euros. |
Using Numbers in Everyday German
German numbers appear in specific contexts: telling time, giving dates, shopping, and providing phone numbers. Understanding these real-world applications helps you use numbers naturally in conversation.
Time Expressions
Time tells has a major pitfall. Halb drei means half past two, not half past three. The German system counts toward the next hour, not from the current hour. Viertel nach (quarter past) and Viertel vor (quarter to) follow the same logic as English.
Age and Shopping
When stating your age or asking prices, use cardinal numbers directly. "Wie alt bist du?" (How old are you?) expects a simple answer like "Ich bin fünfundzwanzig" (I am 25).
| Term | Meaning | Pronunciation | Example |
|---|---|---|---|
| Wie alt bist du? | How old are you? (informal) | vee AHLT bist doo | Wie alt bist du?, Ich bin fünfundzwanzig., How old are you?, I'm 25. |
| Wie viel Uhr ist es? | What time is it? | vee feel OOR ist es | Wie viel Uhr ist es?, Es ist drei Uhr., What time is it?, It's 3 o'clock. |
| Was kostet das? | How much does that cost? | vahs KOS-tet dahs | Was kostet das?, Das kostet fünfundvierzig Euro., How much is that?, 45 euros. |
| halb drei | half past two (lit. 'half three', halfway to 3) | HAHLP drey | Wir treffen uns um halb drei., We meet at half past two. |
| Viertel vor / Viertel nach | quarter to / quarter past | FEER-tel for / FEER-tel nahkh | Es ist Viertel nach acht., It is quarter past eight. |
| der erste / der zweite / der dritte | the first / the second / the third (ordinal) | dehr ERS-teh / TSVEY-teh / DRIT-teh | Heute ist der fünfzehnte April., Today is April 15th. |
| die Telefonnummer | the phone number | dee teh-leh-FOHN-noom-mer | Meine Nummer ist null-drei-null, vier-fünf-sechs., My number is 030-456. |
| die Hälfte | the half | dee HELF-teh | Ich möchte die Hälfte., I would like half. |
How to Study German Effectively
Mastering German requires the right approach, not just more hours. Research in cognitive science shows three techniques produce the best results: active recall (testing yourself rather than re-reading), spaced repetition (reviewing at scientifically-optimized intervals), and interleaving (mixing related topics rather than studying one in isolation).
Why Passive Review Fails
The most common mistake is relying on passive methods. Re-reading notes, highlighting textbook passages, and watching lectures feel productive. However, studies show these methods produce only 10-20% of the retention that active recall achieves. Flashcards force your brain to retrieve information, which strengthens memory pathways far more than recognition alone.
FluentFlash FSRS Algorithm
FluentFlash is built around all three techniques. Our FSRS algorithm schedules every term for review at exactly the moment you are about to forget it. This maximizes retention while minimizing study time.
Your Practical Study Plan
Start by creating 15-25 flashcards covering the highest-priority concepts. Review them daily for the first week using FSRS scheduling. As cards become easier, intervals automatically expand from minutes to days to weeks. You are always working on material at the edge of your knowledge. After 2-3 weeks of consistent practice, German concepts become automatic rather than effortful.
- 1
Generate flashcards using FluentFlash AI or create them manually from your notes
- 2
Study 15-20 new cards per day, plus scheduled reviews
- 3
Use multiple study modes (flip, multiple choice, written) to strengthen recall
- 4
Track your progress and identify weak topics for focused review
- 5
Review consistently, daily practice beats marathon sessions
