Mate (Spanish: [ˈmate], Portuguese: [ˈmatʃi]; sometimes hypercorrected as maté in English, but never in Spanish or Portuguese, where it is often called "jerba"), also known as yerba mate, chimarrão (Portuguese: [ʃimɐˈʁɐ̃w̃]) or cimarrón (Spanish: [simaˈron]), is a traditional South American caffeine-rich infused drink, particularly in Argentina (where it is defined by law as the "national infusion"), Uruguay, Paraguay, the Bolivian Chaco, and Southern Brazil.
