Jaycob

Jaycob is a modern English respelling of Jacob, a name ultimately derived from the Hebrew Yaakov, meaning "supplanter" or "one who follows at the heel," referencing the biblical account of Jacob grasping his twin brother Esau's heel at birth. The spelling with a y reflects a contemporary trend of personalizing traditional names through phonetic variation. The underlying name Jacob has ancient roots and remains widely used across many languages and cultures, with cognates including Jacques, Giacomo, Iago, and Diego.
