Feb. 15th, 2024 07:43 amcaoutchouc (KOU-chook, kou-CHOOK) - n., the sap of rubber trees coagulated into latex but not otherwise treated.
If I were using tags, this one would get "learned from reading Encyclopedia Britannica 11th edition" -- and yes, there's others. Also called natural rubber, India rubber, latex, and caucho. The most common commercial rubber tree is the Pará rubber tree (Hevea brasiliensis) but several other plants have latex in their sap, including dandelions. Fun fact: the substance rubber gets its name from being used in erasers, which rub out mistakes. The word's been in English since around 1770, from Spanish cauchuc, the now obsolete older form of caucho, probably from some language of Amazonian Peru or Ecuador: compare Quechua kawchu and Tupí cau-ucha.
