Plural of grille; multiple decorative or functional latticed screens, frameworks, or grids of bars or wires.
From French 'grille' meaning 'lattice' or 'grill,' derived from Latin 'craticula' meaning 'small grating.' The word entered English in the 18th century and is used for both decorative and functional applications.
Grilles appear everywhere from cathedral windows to car radiators—the same lattice pattern has been used for centuries because it's strong, lets things through, and looks beautiful.
