The word “cutch” refers to a type of dye that is derived from the heartwood of certain tropical trees, particularly the *Acacia* species. It is used to produce a reddish-brown color for textiles. Additionally, “cutch” can also refer to a material or substance made from this dye. In some contexts, it may denote a type of tannin used in the tanning of leather. The term is not commonly used in everyday language and may be more familiar in specific industries related to dyeing and tanning.
