What is the meaning of the name Caidin ?

The baby name Caidin is a Male name , 2 syllables long and is pronounced /ˈkeɪdɪn/ (KAY-din).

Caidin is Gaelic, Irish in Origin.

Caidin is a modern American given name deriving from the Caden/Caiden family, itself based on the Irish and Scottish Gaelic surname Mac Cadain and the medieval given name Cadan. Cadan traces to the Gaelic root cath, "battle," with the diminutive -an, yielding the sense "little battler" or "warrior's son." The battle root also appears across Celtic languages (compare Welsh cad), reinforcing the martial meaning. Caidin adopts a contemporary spelling while preserving this Celtic etymology.

Used as a given name only rarely before the 1990s, it rose in visibility amid the Aidan/Jayden naming wave, though Caidin remains the least common spelling. The form is also seen as a surname, most notably borne by author Martin Caidin. Closely related variants include Caden, Caiden, Caidan, Cayden, Kaden, Kaiden, Kayden, and Cadyn; feminine use occurs but the name is primarily masculine in current English-speaking practice.
