What Does the Name Jac Mean?
Jac is a short form used in several languages. Its most common derivation is from Jacob and its relatives. In Welsh, Jac is a diminutive of Iago, the Welsh form of James, which comes from the Hebrew name Ya'aqov (Jacob). That Hebrew name is traditionally understood as supplanter or heel holder, from a root meaning heel or to follow. The same source lies behind the Dutch use of Jac as a short form of Jacob or Jacobus, and the English use of Jac as a short form of Jacob or the feminine Jacqueline. In these cases the meaning is supplanter. Separately, Jac is used in Welsh and English as a form of Jack, which developed in the Middle Ages as a diminutive of John. John comes from the Hebrew Yochanan, meaning Yahweh is gracious or God is gracious. So Jac can mean either supplanter or God is gracious, depending on which name it stands for.
Jac Name History & Origins
Jac appears as a given name in Wales, the Netherlands, and English-speaking countries. In Welsh, it is a traditional diminutive of Iago (James) and also serves as the Welsh equivalent of the English name Jack. In the Netherlands, Jac is a long-established short form of Jacobus and Jacob; the abbreviated form Jac. appears in Dutch names such as that of the naturalist Jac. P. Thijsse (Jacobus Pieter Thijsse). In English, Jac is used as a short form of Jacob or Jacqueline, and less often as a variant spelling of Jack. The name Jack itself arose in medieval England as a pet form of John, through intermediate forms like Jankin, and became so common that it was used as a generic term for a man. The spelling Jac without the final k is not the usual English form of Jack, but it is the normal Welsh spelling and is also found in Dutch.
