A large South American tree (Manilkara bidentata) with dense, durable hardwood used in construction, shipbuilding, and tool-making.
From Tupi or other indigenous Amazonian languages. This word, like ausu, entered English through botanical and forestry documentation of tropical resources.
Ausubo is so hardwood-heavy that freshly cut logs sink in water—it's been used in ship construction for centuries because nothing rots it, making it the wood of choice for underwater structures.
