"Blend of Ja and Kayden"
The name Jakayden is commonly a male name.
Jakayden is a modern American coinage, first recorded in United States birth data in 2008. Its form reads as the Ja- opening familiar from Jayden joined to Kayden, so it is best described as a blend of those two name elements. It has no earlier recorded history in any language, and no meaning can be assigned to it beyond the parts it is built from.
The pronunciation of Jakayden is juh-KAY-den.
