Reginaldus is Germanic in Origin.

Reginaldus is the Latinized medieval form of a Germanic dithematic name built from ragin “counsel, advice” and wald “rule, power.” Its sense is often rendered “ruler’s counsel” or “one who rules by counsel.” The form Reginaldus appears widely in Latin charters, chronicles, and university records, serving as the standard clerical equivalent of vernacular Reynold/Reginald across Western Europe.

Carried to England by the Normans, the name thrived in the 12th–14th centuries, then declined, later reviving as Reginald in 19th‑century Britain. Notable bearers include Rainald of Dassel, archbishop of Cologne, and Saint Reginald of Orléans. Major variants: English Reginald, Reynold/Raynald; French Renaud/Renauld; German Reinhold/Rainald; Italian Rinaldo; Spanish and Portuguese Reinaldo/Reginaldo; medieval Latin Reynaldus alongside Reginaldus. Related Norse Rögnvaldr (Ragnvald) underlies Scottish Ronald, often conflated historically. Diminutives include Reggie (English) and, in Italian tradition, Rinaldino.
