German Indefinite Articles: How to Use “Ein” & “Eine” Correctly

Introduction

German indefinite articles (ein, eine) are used to refer to something not yet specified or introduced in a conversation. Unlike definite articles (der, die, das), which refer to known nouns, indefinite articles point to something new or one among many. To use them correctly, you need to understand both gender (masculine, feminine, neuter) and case (nominative, genitive, dative, accusative). This guide covers the basics with examples, a table, and quizzes. For a more detailed explanation of German articles, check out our guide: here.

Table of German Indefinite Articles

Here’s a chart showing how indefinite articles change with the nouns Mann (masculine), Frau (feminine), and Kind (neuter) depending on the case. If you’d like to review the cases, take a look at German cases.

	Masculine (ein Mann)	Feminine (eine Frau)	Neuter (ein Kind)
Nominative	ein Mann	eine Frau	ein Kind
Genitive	eines Mannes	einer Frau	eines Kindes
Dative	einem Mann	einer Frau	einem Kind
Accusative	einen Mann	eine Frau	ein Kind

Remember there is no separate indefinite article for plural nouns in German. Instead, use “keine” for negatives, or no article at all for non-specific references in the plural.

Example Sentences with Indefinite Articles

Below are examples of indefinite articles in various cases. Pay attention to how the article changes based on the noun’s role in the sentence.

German	English

Usage of Indefinite Articles

Indefinite articles (ein, eine) point to something not specifically identified or introduced before. For example:

• ein Mann = a man (not previously mentioned, or one of many)
• eine Frau = a woman (any woman, no prior reference)
• ein Kind = a child (not known or unspecified)

Compare these to definite articles (der, die, das), which imply a known or previously mentioned noun. For a deeper look at the difference, see definite vs indefinite articles or German definite articles.
