Grüner

Grüner is a German-language term with multiple uses. As an adjective, grüner is the inflected form of grün used before masculine singular nouns or in the comparative sense, meaning "greener" or "more green." It appears in phrases such as grüner Tee (green tea) or ein grüner Wald (a green forest).

When capitalized as Grüner, the word can function as a noun meaning "a member of the Green party" (Der Grüne) and, in plural, as "Die Grünen," referring to the Green political movement or party as a group. The usage is common in German-speaking regions, including Germany, Austria, and parts of Switzerland, where the Green parties exist under the broader Bündnis 90/Die Grünen or Die Grünen branding.

Grüner is also a surname of German origin. As a family name, it is derived from the same root as the adjective grün and from place-name or nickname origins; bearers are found in German-speaking countries and in communities with German heritage.

Related terms include Grün (the color green), Grüne/Die Grünen (the Green Party), and the general concept of green politics.
