What Alonzo Means
Alonzo means noble and ready, or eager for battle. The Germanic compound joins nobility or combat to a word meaning prepared, so it describes readiness rather than achievement.
Where Alonzo Comes From
Alonzo is a Spanish and Italian form of Alfonso, from a Visigothic name reconstructed as Athalfuns or Hadufuns — adal, noble, or hathu, battle, joined to funs, ready or eager. It was the dynastic name of the kings of Asturias, León and Castile, so its history is Iberian long before it is anything else. Alphonse, elsewhere on this site, is the French form of the same compound and birth records mark that one reviving too.
