German Ordinal Numbers Spoken: erste, zweite, dritte

You've drilled the cardinals until einundzwanzig stops flipping in your head. Then someone says am dritten Stock for the floor, der zweite links for the door, or heute ist der erste for the date, and a familiar number suddenly grows a tail you didn't expect. That tail is the ordinal ending, and it's the part that makes spoken ordinals trip up learners who can count perfectly well.

Good news: German ordinal numbers are built from the cardinals you already know, with one small suffix and a handful of irregulars. The harder part is purely a listening problem, because the ending shifts depending on the sentence. This guide walks through how ordinals are formed, how they actually sound, and where the traps hide.

How German ordinal numbers are formed

There are two simple rules and three exceptions.

• 1 to 19: add -te to the cardinal. Vier becomes vierte, fünf becomes fünfte, zehn becomes zehnte.
• 20 and up: add -ste. Zwanzig becomes zwanzigste, hundert becomes hundertste.

The three you have to memorize:

• erste (first), not einte
• dritte (third), not dreite
• achte (eighth), with only one t, not achtte

One more to watch: siebte (seventh) drops the -en of sieben. You'll also hear the fuller siebente occasionally, but siebte is the everyday form.

The bigger ordinals: 20, 21, 100 and beyond

From 20 up, you switch to -ste, and the reversed ones-and-tens rule from the cardinals comes right along for the ride.

So the 21st is einundzwanzigste: the same flipped ein-und-zwanzig you already know, plus -ste on the end. If the reversed order still feels alien underneath the ordinal, we unpack where it comes from in Why Are German Numbers Backwards?

Why the ending keeps moving

Here's the part that catches learners off guard: ordinals are adjectives, so they take adjective endings. The -te core stays put, but the final letters change with gender, case, and the article in front.

• der dritte Tag (the third day, subject)
• am dritten Tag (on the third day)
• ein dritter Versuch (a third attempt)
• das dritte Mal (the third time)

For listening, this is mostly good news: the heart of the word, dritt-, never changes. Only the last letter or two move. Once you stop expecting one fixed form and instead listen for the dritt-, viert-, zwanzigst- stem, the shifting tail stops being a problem.

Ordinals in dates and the written dot

The most common place you'll meet ordinals out loud is the calendar. Spoken German dates lean entirely on them.

• Heute ist der erste Mai. (Today is the first of May.)
• Am dritten März fliege ich. (On the third of March I fly.)
• Der Termin ist am einundzwanzigsten. (The appointment is on the 21st.)

In writing, an ordinal is just the digit plus a period: 1. Mai, 3. März, 21. Juni. That period is the German equivalent of the English -st, -nd, -th, and it tells you to read the number as an ordinal: der erste Mai, not eins Mai. The same dot logic shows up for floors (3. Stock, the third floor) and rankings (2. Platz, second place). The full date pattern, including months and years, is covered in German Dates: Days, Months, Years.

How to train your ear for ordinals

Reading the rules won't transfer to comprehension; listening will. Four things that work for ordinals specifically:

1. Listen for the suffix, not a new word. Vierte is just vier with a -te tail. Train yourself to hear the cardinal first, then catch the ending that turns it ordinal.
2. Lock onto the stem, ignore the tail. Because the case ending moves (dritte, dritten, dritter), focus on the unchanging core (dritt-) and let the final letter wash past.
3. Drill them in dates. Dates are where ordinals live. Practice hearing der erste, am dritten, der einundzwanzigste in full phrases, not as isolated words.
4. Keep the irregulars in the mix. Interleave erste, dritte, siebte, and achte with the regular forms so the exceptions stop surprising you.

That's why we built Zahlhaus the way we did: native audio, instant scoring, and numbers mixed in real contexts so you train your ear for German numbers the way you'll actually hear them, ordinals and cardinals together, never one tidy list at a time.
