Caidyn, pronounced /ˈkeɪdən/, is of Irish origin and means "fierce in battle." It is a unisex name, although it is more commonly used for males. The name gained popularity in the late 20th century, particularly in English-speaking countries like Ireland, the United States, and Canada. Caidyn is often associated with Irish culture and heritage, and it can be considered a unique yet recognizable choice for parents looking to give their child an uncommon yet meaningful name.
"Caidyn saw a peak in popularity around the mid-2000s, with 35 births in 2004 and remaining relatively high until 2009. Since then, its usage has declined, with only 6 births recorded in 2021 and 8 in 2022."
