Alonzo begins his story centuries ago in the sun-warmed courts of medieval Iberia, where Alfonso—“the noble and ready” in old Germanic tongue—shed a syllable, slipped across the Pyrenees, and emerged with a jaunty z: Alonzo. Spoken in Italian as ah-LOHN-tsoh and in English as uh-LAHN-zoh, the name rolls off the tongue like a flamenco flourish, equal parts velvet and verve. History paints it on knights’ shields and explorers’ maps, yet it has never felt shackled to the past; in modern times it dribbles down basketball courts with Hall-of-Famer Alonzo Mourning and solves logic puzzles through mathematician Alonzo Church. American parents seem to savor its old-world spice in steady spoonfuls—hovering around the mid-400s in popularity for decades—proof that classic flair can age like Rioja, not like leftovers. Choosing Alonzo for a son is a bit like handing him a passport stamped “nobility, readiness, and just a dash of swagger,” inviting him to stride into life with cape unfurled and a grin that knows both poetry and play.
