Combination of Jay and Leah
Jayleah is a modern American invention, likely created by blending the prefix 'Jay' with the classic name 'Leah'. While Jay can refer to the bird or mean 'to rejoice', and Leah traditionally means 'weary' or 'meadow', this compound name is chosen primarily for its melodic sound rather than its etymological roots.
