What does groined mean?
Groined is an adjective used chiefly in architecture to describe vaulting formed by the intersection of two barrel vaults. The intersecting edges are called groins, and they may be emphasized by ribs, creating a ceiling divided into elegant geometric compartments. Groined construction was especially important in medieval and Gothic architecture, where it allowed builders to cover broad spaces with relatively few supports while producing a richly patterned effect. The word also occurs more broadly in descriptions of churches, cathedrals, cloisters, halls, and other historic interiors. It should not be confused with grained, which concerns a surface resembling or possessing grain. Although groined can occasionally appear in literary or historical writing, it remains primarily a specialized architectural term rather than part of everyday general vocabulary.

Where does groined come from?
The adjective groined was formed from groin, a word for the edge or supporting rib where two vaults intersect. English groin came through Middle English from Old French groin and ultimately from Latin granum, meaning grain. The architectural sense developed from the idea of ridges or grooved lines formed where curved surfaces meet.
