Caius

In Latin, Caius is an archaic spelling of the Latin praenomen Gaius, pronounced /ga:ius/. In early Latin, the letter C was used for both /g/ and /k/; and the names Gaius and Gnaeus were spelt Caius and Cnaius and continued to be so in inscriptions, after the letter G was introduced, and C was confined to the /k/ sound. Notably, the name of Gaius Iulius Caesar is abbreviated CIC.

In English, Caius is a latinized spelling of the last name of John Keys of Gonville and Caius College, Cambridge.
