acai

Where does the word "acai" come from? It comes from Tupi ïwasa'i, passing through Portuguese before entering English (1990s).

Acai’s story begins in Tupi: ïwasa'i meant “a small purple palm fruit.” Named the dark purple palm fruit. By 1600s, the word had taken hold in Portuguese as açaí. Portuguese settlers took the name from the Tupi-speaking peoples of the lower Amazon, where the berry is a staple food. It reached English by 1990s as acai. Entered English amid the global health-food boom. Today, acai means a small, dark purple Amazonian palm fruit marketed worldwide for its antioxidant content.
