What Are German Indefinite Articles?
German indefinite articles (unbestimmte Artikel) are used to refer to non-specific nouns — the equivalent of 'a' or 'an' in English. Like definite articles, indefinite articles change based on three factors: the grammatical gender of the noun (masculine, feminine, neuter), the case (nominative, accusative, dative, genitive), and number. However, indefinite articles only have singular forms; there is no indefinite plural.
German indefinite articles are ein (masculine), eine (feminine), and ein (neuter) in the nominative singular. They change form based on gender, case, and number — ein Mann, eine Frau, ein Kind in nominative, but einen Mann, eine Frau, ein Kind in accusative.

Common mistakes
Using indefinite articles for plural nouns — Correct: Indefinite articles only exist in singular — use no article for indefinite plural
Treating masculine and feminine indefinite articles the same in all cases — Correct: Masculine 'ein' changes more (einen, einem, eines); feminine 'eine' changes only in dative/genitive (einer)
Confusing masculine 'ein' with neuter 'ein' — thinking they are identical in all cases — Correct: They look the same in nominative/accusative, but differ in dative (einem/einem) and genitive (eines/eines) — actually same, but represent different genders
Forgetting the -en in accusative masculine — Correct: Accusative masculine must be 'einen,' not 'ein'
