Ready or brave, in the shared second element of its Germanic name family.
The Real Academia Galega names guide lists Alonso as a Spanish equivalent of Afonso. It describes a convergence of the Germanic names Adefonsus, Ildefonsus and Aldefonsus, sharing the second element funs, glossed ready or brave. This explains a shared element of that name family, rather than a settled translation of every element or a promise about a child. The older licensed battle gloss is not independently established by this source.
Origin
Spanish Alfonso-related form with Germanic ancestry
The English personal-name definition identifies Alonso as a Germanic-language Alfonso variant; the Spanish section explicitly gives the Alfonso equivalent. Alfonso’s Spanish history traces medieval Latin to Gothic. This transmission chain does not settle its deeper literal elements.

The exact personal-name definition establishes the Alfonso relationship. Alfonso’s Spanish entry gives a Gothic source distinct from the proposed battle/ready formation in Ildefonso. Those elements are not transferred to Alonso, and the licensed eager-for-battle gloss is not presented as settled. Credit: Wiktionary contributors.
