What does 'tracery' refer to in Gothic architecture?

In Gothic architecture, 'tracery' specifically refers to ornamental stone openwork that is primarily used in windows, providing both structural support and decorative detail. Tracery typically features intricate patterns and designs, allowing light to filter through while simultaneously enriching the visual complexity of the window. This decorative aspect is an essential characteristic of Gothic style, often seen in cathedrals and churches, where large stained glass windows are framed by elaborate tracery.

The use of tracery enhances the verticality and ethereal quality that is hallmark to Gothic architecture, enabling the creation of large, visually stunning windows that are a focal point of the structure. In contrast, other architectural terms listed do not capture the specific ornamental and functional qualities associated with tracery in Gothic designs.
