ringförigen

Ringförigen is a German inflected adjective meaning ring-shaped or annular. It is a declined form of the base adjective ringförmig, used to describe objects that have a circular outer boundary or a hollow center. In German, adjectives are declined to indicate gender, number, and case, and ringförigen appears in several declined forms, most notably in plural after definite articles (die ringförigen Strukturen) or in other declined environments such as with the definite article in different cases (der ringförigen Struktur, den ringförigen Strukturen).

The term itself is not a standalone noun; it is an adjective form. It is commonly found in scientific and technical writing, where annular shapes occur in biology, geology, and anatomy—for example, ringförmige Strukturen in tissue, oder ringförmige Ringe in geologischen Gebilden. The form can also appear in other cases, depending on the noun and article, such as mit der ringförigen Struktur (dative singular) or den ringförigen Strukturen (accusative plural).

Etymology: ringförigen derives from Ring (ring) + förmig (shaped), a productive combination in German to form shape-based adjectives.
