zweiflügelig

Zweiflügelig is a German adjective that translates to "two-winged" or "double-winged." It is primarily used in the context of architecture and botany.

In architecture, zweiflügelig describes a door or a window that consists of two independent panels or casements that open outwards or inwards. This is a common design for entrances to buildings, particularly in traditional European architecture, and also for large windows. The term emphasizes the dual nature of the opening mechanism.

In botany, zweiflügelig refers to a seed or fruit that has two wing-like appendages. These wings aid in the dispersal of the seed by the wind. Examples can be found in certain species of trees and plants where these structures facilitate their propagation. The adjective highlights a specific morphological characteristic of the plant reproductive part.

The term is straightforward in its meaning, indicating the presence of two distinct parts that function as wings or panels. Its usage is consistent across different fields, denoting duality in form or function related to the concept of wings.
