What is the meaning of the name Reinerio ?

Reinerio is Germanic in Origin.

Reinerio is a rare Iberian form of a pan‑European name descending from medieval Latin Rainerius, itself from a West Germanic compound of ragin “counsel, decision” and heri/harjaz “army.” The core sense is “wise counsel to the army” or “deciding warrior.” In Iberian and Italian records the spelling alternates with Rainerio and Raniero, reflecting regional pronunciation and Latinized church registers.

Use is intermittent across the Hispanic world, with earlier attestations in early‑modern parish books and occasional modern revivals. The wider name family has deep medieval visibility: Saint Ranieri (Rainerius) of Pisa, a 12th‑century pilgrim and city patron, fostered Italian popularity; Norman influence spread Rayner to England; French Rainier and German Rainer remain established. Related variants and cognates include Rainier, Rainer, Rayner, Reiner, Ranieri/Raniero (It.), and Latin Rainerius; diminutives such as Rei and Reni occur in contemporary use. The name carries a dignified, martial‑sage tone.
