A board or plank in construction with a beveled or angled edge; also called a cant.
Compound of 'cant' (an angled edge or slope) plus 'board.' The word 'cant' comes from Middle Dutch 'kant' meaning edge or corner, reflecting construction terminology.
Carpenters and builders use 'cantboards' constantly but most people never hear the word—it's the angled piece that gets cut off corners or used to create sloped surfaces in roofing and trim work.
