Meaning:rejoice or happy
Cai is a gender-neutral name of Latin and Welsh origin. Meaning “rejoice” or “happy,” Cai is a diminutive of Caius, a Roman male given name. It’s particularly popular in Wales, where it's the Welsh variant of Sir Kay, King Arthur’s foster brother and an important character in Arthurian mythology. Sir Cai is prominent in medieval Welsh texts about the fabled King of Camelot and is said to have many super-human qualities. With such a heroic namesake, it won’t be a surprise if baby Cai grows up with a thirst for adventure. Coincidentally, Cai can also be a nickname of the popular Irish girl’s name Caitlin, which means “pure.” Together, these meanings set baby Cai up to be a chivalric knight worthy of a seat at the Round Table.
