Etymology & Historical Origin of the Baby Name Caius

 Caius/Gaius is an Old Latin praenomen, a boy’s given name chosen by his parents, in the Roman Republic’s three-part naming system (known as the Tria Nomina) – comprised of the praenomen, the nomen, and the cognomen – or, in modern-speak, the personal name, the family name, and the nickname).  Like Lucius, Marcus, Octavius and Titus, Gaius was an extremely common given name in Ancient Rome (think: Gaius Julius Caesar).  Caius is a variant spelling, reflecting the early Roman confusion regarding the use of gamma (which they used for both the “g” and “k” sounds, having little use for the Greek kappa).  The origin of Gaius is most likely Etruscan (an extinct Italic language eventually replaced with Latin), so the name’s meaning is not entirely known/certain.  There are some theories, however.  For one, the Late Latin “gaius” was the word for the jay or magpie (as in the chatty, colorful bird), possibly stemming from the ancient praenomen.  Others theorize the word is related to the Proto-Indo-European (prehistoric) root *ghel- meaning “to shine” from which the Latin “gavisus” (glad, rejoicing) finds its hypothetical origin. We like the theory that Gaius means “happy, rejoicing” in keeping with Ancient Rome’s naming system and how other masculine praenomina reflected positive attributes: for example, Faustus (lucky, fortunate) and Lucius (light).  The name Gaius also appears in the Biblical New Testament as a companion of Saint Paul.

OF THE BOY NAME CAIUS

 Neither Gaius nor Caius has ever been a popular enough masculine name in America to land a spot on the U.S. Top 1000 list. Case in point, the name Caius was given to 108 baby boys in 2013 while Gaius was given to a mere 29.  While common in the days of the Ancient Roman Republic, today these names are really quite rare.  We like the history and the theorized etymologies – and we love the connection to Gaius Julius Caesar (famed conqueror of Gaul) as well as Gaius Octavius, known simply as Augustus (i.e., venerable).  Caius and Gaius – both abbreviated as C. – are among the oldest names in Western Civilization.
