"Bauch" is masculine in German — the correct article is der. The plural is die Bäuche. In English, Bauch means "belly" or "stomach".
Gender rule: der Bauch is masculine. As with most body part nouns in German, there is no reliable ending-based rule for the gender — die Hand, das Knie, and der Bauch all differ. The safest approach is always to learn each noun with its article from the start. See all gender patterns in the Article Rules and a full overview at the german articles.

Common Mistake with Bauch
❌ Common mistake: Ich habe Schmerzen in meinen Bauchen.
✅ Correct: Ich habe Schmerzen in meinem Bauch. (singular) or Alle hatten volle Bäuche. (plural)
💡 Why: The plural of der Bauch is die Bäuche — not Bauchen. The ending -en is not used for this noun in the plural. Note also that when talking about stomach pain, German uses the singular mein Bauch far more naturally than the plural — unlike in English where "stomach" stays singular anyway.

1. Das Grummeln ___ Bauches war deutlich zu hören.
- A) der
- B) dem
- C) des
Check Answer
"Das Grummeln ___ Bauches" — whose rumbling? The stomach's. This is a possession relationship expressed with the genitive case. For masculine nouns, the genitive article is des and the noun adds -es: des Bauches. Option A) der is the genitive article for feminine nouns. Option B) dem is dative.
2. Das Kind liegt auf ___ Bauch und schläft.
- A) den
- B) der
- C) dem
Check Answer
The preposition auf can take either accusative (movement toward) or dative (location/rest). Here the child is lying still — no movement — so the dative is required: auf dem Bauch. For masculine nouns, the dative article is dem. Option A) den is accusative. Option B) der is the dative article for feminine nouns.
3. Ein rund___ Bauch ist noch kein Grund zur Sorge.
- A) -e
- B) -en
- C) -er
Check Answer
After an indefinite article in the nominative, masculine nouns take the adjective ending -er: ein runder Bauch. Because ein does not carry a visible masculine signal in the nominative (it looks the same as neuter), the adjective must step in and carry it — this is called the strong ending. Option A) -e is the ending after a definite article in the nominative for all three genders. Option B) -en is the weak ending used after der or in most other case-gender combinations.

Practice German Articles →Frequently Asked Questions
Is Bauch masculine, feminine, or neuter in German?
Bauch is masculine — the correct article is der. There is no single ending-based rule that reliably predicts the gender of body part nouns in German, so the best habit is to always learn every noun with its article from the beginning. For a full overview of gender patterns, see the Article Rules.
What is the plural of Bauch in German?
The plural is die Bäuche — the vowel takes an umlaut (a → ä) and -e is added. Do not use Bauchen — this is a very common learner error. In the dative plural, a further -n is added: den Bäuchen.
What is the difference between Bauch and Magen in German?
Der Bauch refers to the belly or abdomen — the external body area. Der Magen is the anatomical stomach — the internal organ responsible for digestion. In everyday speech, Germans often use Bauch loosely to mean both (e.g. Bauchschmerzen for stomach ache), but in medical contexts the distinction matters.
What is the genitive of der Bauch?
The genitive singular is des Bauches. Masculine and neuter nouns add -es or -s in the genitive singular — both des Bauches and des Bauchs are acceptable, though des Bauches is more common in written German. See the Cases Overview for more detail.
