Numbers (Zahlen)

Numbers show up everywhere on the exam and in daily life: prices, addresses, phone numbers, dates, age. Learn 0-20 solidly first - everything above 20 is built from the same pieces.

0-20

Pattern from 13-19: [digit]+zehn (dreizehn = drei + zehn), except 16 and 17 shorten sechs→sech and sieben→sieb.

Compound numbers: the "flip" rule

Between 21 and 99, German says the units before the tens, joined by und - the reverse of English:

21einundzwanzig(literally "one-and-twenty")
32zweiunddreißig("two-and-thirty")
47siebenundvierzig("seven-and-forty")

Written as one word, no spaces. This trips up almost every English-speaking learner at first - say numbers slowly until the flip becomes automatic.

Ordinal numbers: mostly -te, then -ste from 20

1. erste (irregular)7. siebte (irregular)
2. zweite8. achte
3. dritte (irregular)20. zwanzigste

Used for dates: "am fünfzehnten Juni" (on the 15th of June) - see Lesson 41.

Asking and telling age
