Frequently Asked Questions
No, it is a highly specialised term from Spanish, used primarily in botanical, forestry, and historical industrial contexts.
Yes. The term broadly applies to several South American tree species in the genera Schinopsis and Aspidosperma, all known for their hardness and tannin content.
It is pronounced /keɪˈbrɑːtʃoʊ/ in American English and /keɪˈbrɑːtʃəʊ/ in British English. The stress is on the second syllable.
Its use has declined due to overexploitation and the development of synthetic alternatives. It is sometimes used for specialty flooring, heavy construction, or as charcoal, but is not a major commercial timber.
