Aiden is a popular English variant of the Irish name Aidan. The name has surged in usage since the late 20th century, particularly in the United States, where it has become a top choice for boys, often spelled as Aiden, Ayden, or Aidan. Etymology The name traces back to the Old Irish name Áedán, meaning "little fire," a diminutive of Áed (see Aodh), which means "fire." Aodh was also the name of a Celtic sun god. Thus, Aiden carries connotations of fire and brightness. The spelling Aiden developed as an anglicized variant alongside Aidan, both derived from the Irish Aodhán. Historical and Cultural Context In early Irish history, the name Áedán was borne by a 6th-century king of Dál Riata and several early Irish saints, including a 6th-century bishop of Ferns and a 7th-century bishop of Lindisfarne, who is known as Saint Aidan. The name Aodh was also widely used among early Irish high kings and mythological figures. Modern Popularity In the latter part of the 20th century, Aiden gained popularity in America, likely due to its pleasant sound and similarity to other popular names such as Braden and Hayden. According to Wikipedia, Aiden peaked as the 13th most popular name for boys in the United States in the 2010s, with over 129,000 boys given the name. Variants like Ayden and Aden are less common but still widely used. Variants and Related Names Aiden shares linguistic roots with several variants across languages and cultures, including Aaden, Aden, Aidan, Aydan, Ayden (also used in French), Eyden (French), and the original Irish forms Aodh and Aodhán.
