Countable and Uncountable Nouns | German Grammar

Like English, German splits nouns into two kinds: count nouns, which name discrete things you can number directly (ein Buch, zwei Bücher), and mass (uncountable) nouns, which name substances or abstractions you can't count one-by-one (Wasser, Brot, Geld, Information). The categories mostly line up between the two languages — but not perfectly, and the small mismatches are exactly where English speakers slip. On top of that, German measures uncountables with a phrase structure that looks deceptively like English yet differs in one critical way: there is no word for "of." That single difference is the heart of this page.

What makes a noun uncountable

A mass noun names something seen as an undifferentiated whole — a liquid, a material, a powder, a collective, or an abstraction — rather than as separate units. In their generic, "substance" meaning, these nouns normally:

have no plural (you don't say zwei Wässer to mean two waters-as-substance),
take no indefinite article in generic use (you say Ich trinke Wasser, not ein Wasser, for water in general).

Mass noun	Meaning	Type
das Wasser	water	liquid
das Brot	bread	foodstuff
die Milch	milk	liquid
das Geld	money	substance/abstract
der Zucker	sugar	powder
die Luft	air	substance
das Gepäck	luggage	collective

Ich trinke jeden Morgen Kaffee.

I drink coffee every morning. (generic substance — no article, no plural)

Hast du genug Geld dabei?

Do you have enough money on you? (Geld is uncountable — no plural)

Wir brauchen noch Mehl und Zucker.

We still need flour and sugar. (both mass nouns, bare)

💡

When you mean a substance "in general," drop the article entirely: Ich esse gern Brot (I like bread), not ein Brot. The bare noun is the generic mass reading. See omission of articles for the full picture of when German leaves the article out.

Measuring uncountables: the no-von rule

You can't count a mass noun directly, so to specify a quantity you put a measure word in front of it — a container, a unit, or a portion. English does the same, but English glues the two nouns together with "of": a glass *of water, two kilos of flour, a slice of bread*.

German uses no "of" at all. The measured substance follows the measure word directly, with nothing between them. This is the rule to burn in:

measure word + substance noun, side by side, no preposition.

Ich hätte gern ein Glas Wasser.

I'd like a glass of water. (Glas Wasser — no von!)

Kannst du zwei Kilo Mehl kaufen?

Can you buy two kilos of flour? (Kilo Mehl, directly)

Sie aß eine Scheibe Brot mit Käse.

She ate a slice of bread with cheese. (Scheibe Brot)

Wir bestellen eine Flasche Wein.

We're ordering a bottle of wine. (Flasche Wein)

The reason there's no preposition is that German treats these as a kind of apposition — the measure word and the substance simply stand next to each other, like ein Glas and Wasser describing the same portion from two angles (its container and its content). English needs of to link them; German doesn't.

💡

The mistake English speakers make most is inserting von: ❌ ein Glas von Wasser. There is no von. Just place the substance immediately after the measure word: ein Glas Wasser.

The substance stays singular — but the measure word can be plural

Here is the second structural surprise. When you order several portions, you pluralize the measure word, but the substance noun stays singular:

Drei Tassen Kaffee, bitte.

Three cups of coffee, please. (Tassen plural, Kaffee singular)

Wir hatten zwei Stück Kuchen.

We had two pieces of cake. (Stück, Kuchen both singular form)

Zwei Glas Bier und ein Wasser, bitte.

Two beers and one water, please. (in everyday usage Glas often stays singular after a number)

Note a quirk visible in that last example: with neuter measure words like Glas and Stück, German very often keeps the measure word itself singular after a number when ordering (zwei Glas Bier, drei Stück Kuchen) — a fixed colloquial habit. Feminine measure words pluralize normally (zwei Tassen, drei Flaschen). Either way, the substance noun never pluralizes: it's always Bier, Kaffee, Mehl, not Biere or Mehle in this construction.

Where German and English disagree about countability

Most mass nouns match across the two languages, but a handful flip — and those are pure transfer-error machines. Learn the mismatches deliberately.

English uncountable, German countable

Some nouns that English treats as uncountable (no article, no plural) are perfectly countable in German:

German	Countable in German	English (uncountable)
die Information	eine Information, die Informationen	(an item of) information
das Brot	ein Brot (a loaf), zwei Brote	bread
der Rat / der Ratschlag	ein Ratschlag, Ratschläge	(a piece of) advice
das Möbelstück / die Möbel	die Möbel (plural)	furniture

Ich habe eine wichtige Information für dich.

I have an important piece of information for you. (eine Information — German counts it)

Im Ofen sind zwei frische Brote.

There are two fresh loaves in the oven. (Brot = a loaf, countable; English needs 'loaves')

So das Brot is genuinely two things at once: uncountable "bread" as a substance (Ich esse Brot) and countable "a loaf" (ein Brot, zwei Brote). Context tells you which.

English countable, German uncountable

Going the other way, some collectives are uncountable in German where English happily counts:

Mein Gepäck ist noch nicht angekommen.

My luggage hasn't arrived yet. (Gepäck has no plural; English 'pieces of luggage' to count)

Wir haben neue Möbel gekauft.

We bought new furniture. (Möbel is used as a plural collective; no 'a furniture')

Common Mistakes

❌ Ich möchte ein Glas von Wasser.

Incorrect — there is no von in a measure phrase; it's a direct English transfer of 'a glass of water'.

✅ Ich möchte ein Glas Wasser.

I'd like a glass of water.

❌ Kauf bitte zwei Milche.

Incorrect — Milch is a mass noun and has no plural.

✅ Kauf bitte zwei Liter Milch.

Please buy two litres of milk.

❌ Wir hätten gern drei Tassen Kaffees.

Incorrect — pluralizing the substance noun; only the measure word takes the plural.

✅ Wir hätten gern drei Tassen Kaffee.

We'd like three cups of coffee. (Kaffee stays singular)

❌ Ich habe eine Information... ähm, ich meine ein Information.

Incorrect gender, but the bigger point: do not avoid the article — Information IS countable in German.

✅ Ich habe eine wichtige Information für dich.

I have an important piece of information for you.

❌ Ich brauche ein Geld.

Incorrect — Geld is uncountable; no indefinite article in this sense.

✅ Ich brauche Geld.

I need money.

Key Takeaways

Mass nouns in generic use take no article and no plural: Ich trinke Kaffee.
Measure phrases use no "of": ein Glas Wasser, never ein Glas von Wasser.
The measure word can pluralize; the substance noun stays singular: drei Tassen Kaffee. Neuter measure words like Glas/Stück often stay singular after a number (zwei Glas Bier).
Countability doesn't always match English: eine Information and ein Brot (a loaf) are countable in German, while Gepäck and Möbel behave as uncountable collectives.
