Supplanter
Jakalyn is a modern American invention, likely created by blending the name Jack or Jacob with the popular feminine suffix -lyn. As a derivative of Jacob, it ultimately shares the Hebrew meaning of 'supplanter' or 'held by the heel.' It represents a contemporary trend of creating unique feminine forms of traditional masculine names.
