Meaning & origin

Reg is a classic short form of Reginald that saw its peak usage in the 1940s, with the year 1941 marking its highest recorded rank. The name has since maintained a stable trajectory, rarely appearing in modern rankings. Its first recorded year was 1936, reflecting its emergence as a standalone name during that era. While not currently a top pick, Reg carries the sturdy, no-frills charm of mid-century diminutives.

Reg is a diminutive of Reginald, which derives from the Germanic name Raginald, composed of the elements 'ragin' (advice, counsel) and 'wald' (rule). The name was introduced to England by the Normans and became well-established as a standalone short form in the 19th and 20th centuries.
