What does groining mean?
Groining is an architectural noun denoting either the sharp lines where vaulted surfaces meet or, more commonly, the system of intersecting groins that supports and decorates a vaulted ceiling. The basic construction is the groin vault, in which two barrel-shaped vaults meet at right angles, creating a distinctive rib-like pattern. Groining is especially associated with medieval Gothic architecture, where elaborate stone or wooden ribs transformed large interiors into visually dynamic spaces. In modern usage, the term remains primarily specialist and is often used when discussing restoration, historic buildings, or fine masonry detail. It is not a synonym for a body part and should not be confused with the coastal barrier called a groyne. Knowing groining helps readers recognize an important architectural feature and understand how medieval builders solved both the structural and decorative demands of vaulted spaces.
