The root of a brier plant, especially valued for making pipes or other crafted items.
From brier (prickly shrub) + root (from Old English rot, from Old Norse rót). Briarroot was specifically used in European pipe-making.
Briarroot pipes became a luxury item in the 18th and 19th centuries because the wood is dense, takes high heat without cracking, and creates a cool smoke—a perfect storm of practical and pleasurable.
