Cai is a gender-neutral name of Latin and Welsh origin. Meaning “rejoice” or “happy,” Cai is a diminutive of Gaius, a Roman male given name which may be related to the Greek Gaîa. It’s particularly popular in Wales, where it's the Welsh variant of Sir Kay, one of the Knights of the Round Table and an important character in Arthurian mythology. With such a heroic namesake, it won’t be a surprise if baby Cai grows up with a thirst for adventure. Set baby Cai up to be a chivalric knight worthy of a seat at the Round Table.
