[Arizona 词源字典]
- 1861, originally as the name of a breakaway Confederate region of southern New Mexico; organized roughly along modern lines as a U.S. territory in 1863. From Spanish Arizonac, probably from a local name among the O'odham (Piman) people meaning "having a little spring." Alternative theory is that it derives from Basque arizonak "good oaks."[Arizona etymology, Arizona origin, 英语词源]
