"Variant of Reginald"
The name Reginal is commonly a male name from the "Teutonic" origin.
Reginal is a rare variant of Reginald, the English masculine name brought to England by the Normans and derived from Old High German Raginwald, formed from ragin, meaning counsel, and wald, meaning rule or ruler. It corresponds to the same name as the Romance forms Reginaldo and Reginald, with the final d absent, rather than being an independent coinage.
Reginald means "Powerful, Mighty.".
The pronunciation of Reginal is REJ-uh-nul.
