Branches, twigs, and cut vegetation from brush and shrubs, often used as firewood or kindling.
Compound of 'brush' + 'wood' (Old English), used since medieval times for small branches unsuitable for timber.
In historical cooking and heating, brushwood was the poor person's fuel source—easily gathered from forests and quick to burn hot, which is exactly why it became the term for rapid wildfire fuel.
