Wood used to make cogwheels or gears; timber suitable for carving or forming mechanical cog teeth.
From 'cog' (a gear tooth) combined with 'wood,' describing the material traditionally used to manufacture wooden gears.
Before metal gears became standard, wooden 'cogwood'—often made from hardwoods like boxwood—was carved to make the gears for mills and machinery, and the grain pattern of the wood actually mattered for strength.
