Caylum

Meaning & origin

Caylum is a modern respelling of the Scottish classic Callum, which derives from the Latin Columba, meaning 'dove'. The name first appeared on U.S. birth certificates in 2010 and reached its peak popularity in 2018, when it was given to the most babies that year. Since then, its usage has been falling, reflecting a broader trend away from this particular spelling. Despite its rarity (ranked 9,714th in 2025, with only about 1 in 244,011 newborns receiving the name), Caylum's connection to the ancient name Columba gives it a sense of history. The name has not been recorded in any U.S. state's top names, indicating its usage is scattered nationwide rather than concentrated regionally. For parents seeking a distinctive twist on a traditional name, Caylum offers a familiar sound with a unique spelling.

Caylum is a modern respelling of Callum, which is the Scottish form of the Latin name Columba. The name Columba means 'dove' and was borne by the 6th-century Irish missionary Saint Columba, who established a monastery on the island of Iona in Scotland. The spelling Caylum with a 'y' emerged in the 21st century, likely influenced by other popular 'Cay-' names like Cayden.
