Substantivgruppe

Substantivgruppe is a syntactic unit in German grammar that centers on a noun (the head) and includes its modifiers. These modifiers can include determiners, adjectives, numerals, possessives, and other specifiers, as well as postnominal complements such as genitive and prepositional phrases. The group functions as a single unit within a sentence and can serve any role a noun phrase can, for example as subject or object.

In German, the usual internal order of a Substantivgruppe is determiner (such as der, die, das or possessives like mein) followed by attributive adjectives (grüne, alte, große) before the head noun (Auto, Mann, Blume). After the head noun, postnominal modifiers may occur, including genitive attributes (des Nachbarn) and prepositional attributes (im Garten, mit dem Hut). Compound nouns can also appear as the head noun within the group.

Examples illustrate common patterns: der alte Mann, eine kleine rote Blume im Garten, das Auto des Nachbarn, zwei freundliche Jungen aus der Schule. In these examples, the determiner and adjectives come before the noun, while the genitive or prepositional phrases that further describe the noun appear after it. In plural forms, or when the determiner is omitted (e.g., schöne Blumen), the same organizational principles apply.

Substantivgruppe is closely related to the term Nominalphrase or Nominalgruppe used in many grammars; the terms are often used interchangeably, though some sources distinguish subtle differences in scope or terminology. The concept describes the syntactic and morphological packaging of a noun with its modifiers in German.
