What does the name Kaidan mean?
Kaidan is a spelling of Kayden, pronounced the same way, so it shares Kayden's meaning and origin.
Kayden is a variant spelling of Caden, a name created by American parents in the 1990s. Wiktionary describes Caden as coined to rhyme with fashionable names such as Aidan, Braden, Hayden and Jayden. Wikipedia notes that some connect Caden with the Irish surname Mac Cadáin, 'son of Cadán', but calls the etymology debated; we found no evidence that this surname explains the modern name. Kayden has been given to both boys and girls.
How sure is this? Not documented. A recent coinage; the link to Irish Mac Cadáin is a suggestion only.
Related names: Caden, Kaden, Kaiden, Cayden, Jayden.
