German has one word for "a" and it comes in three shapes: ein, eine, einen. Which one you say depends on the gender of the noun and on what the noun is doing in the sentence.
That sounds like a lot of machinery for such a small word. In practice, three rules and about ten phrases cover everything you'll need in a shop, a café or a waiting room — and one of those rules is simply "leave it out."
The Three Forms
masculine
ein
feminine
eine
neuter
ein
| Gender | "the" | "a" | Example |
|---|---|---|---|
masculine | der | ein | ein Mann, ein Kaffee |
feminine | die | eine | eine Frau, eine Frage |
neuter | das | ein | ein Kind, ein Bier |
Quick notes:
- Masculine and neuter share the same form. Only feminine gets the extra -e, so half your work is knowing whether a noun is die or not.
- Which gender a noun has isn't random — der, die or das shows the endings that give it away.
- Our definite article lesson covers the der/die/das side of the same table.
The One Change You'll Hear Constantly: einen
When a masculine noun is on the receiving end of a verb — you order it, have it, want it, buy it — ein becomes einen. Feminine and neuter don't move at all.
A coffee, please.
Einen Kaffee, bitte.
I'd like a beer.
Ich möchte ein Bier.
I have a question.
Ich habe eine Frage.
I have an appointment.
Ich habe einen Termin.
I need a ticket.
Ich brauche eine Fahrkarte.
Do you have a table?
Haben Sie einen Tisch?
Practice these words
Einen Kaffee, bitte.
Quick notes:
- This is why you hear einen so often at a counter: Kaffee, Termin, Tisch, Platz, Moment, Tag are all masculine, and all of them are usually things you're asking for.
- The polite way to order is Ich hätte gern… — Ich hätte gern einen Kaffee. It sits somewhere between "I'd like" and "I'll have," and it's what Germans actually say.
- Saying ein Kaffee instead of einen Kaffee won't stop anyone serving you. Getting it right just makes the sentence land as German rather than translated.
When German Leaves the Article Out
English almost always needs "a." German drops it in three situations, and putting it back sounds wrong.
| Situation | German | Not |
|---|---|---|
Jobs | Ich bin Entwickler. | Ich bin ein Entwickler. |
Nationalities | Sie ist Deutsche. | Sie ist eine Deutsche. |
Plurals | Ich habe Kinder. | Ich habe eine Kinder. |
Fixed expressions | Ich habe Hunger. | Ich habe einen Hunger. |
Quick notes:
- Ein has no plural. "Some books" is just Bücher, with nothing in front.
- The job rule extends to roles and religions: Ich bin Student, Ich bin Vater. Add the article only when you're describing rather than stating — Er ist ein guter Lehrer (he's a good teacher) needs it back, because an adjective has moved in.
- More sentences of this kind are in basic German phrases.
Saying "not a": kein
The opposite of ein isn't nicht ein. German has a dedicated word, and it takes exactly the same endings.
I don't have time.
Ich habe keine Zeit.
That's no problem.
Das ist kein Problem.
I don't have an appointment.
Ich habe keinen Termin.
I don't speak German. (no German)
Ich spreche kein Deutsch.
Practice these words
Ich habe keine Zeit.
Quick note: if you'd use ein in the positive sentence, use kein in the negative one — same shape, one letter in front. Tomorrow's lesson on nicht and kein sorts out which of the two to reach for.
In Dative: einem and einer
You'll meet two more forms in phrases with mit, bei, zu and von. There's no need to study the system yet — just recognise them.
with a colleague
mit einem Kollegen
with a friend (female)
mit einer Freundin
at a doctor's
bei einem Arzt
in a month
in einem Monat
Practice these words
mit einem Kollegen
Quick note: the pattern is that masculine and neuter take einem, feminine takes einer. Learn these as whole phrases and the rule will arrive on its own later.
Three Mistakes to Avoid
Adding "a" to your job. Ich bin ein Ingenieur is the most common sentence non-natives say in interviews. It's Ich bin Ingenieur.
Using eine for anything that isn't feminine. When you're unsure of the gender, ein is the better guess — it covers two of the three genders.
Forgetting einen after möchte, habe, brauche and nehme. These four verbs come up in every shop, and they all push masculine nouns into einen.
