Issy

Issy is a diminutive form of names beginning with Is-, most commonly Isabel or Isabelle, which derive from the Hebrew Elisheba, meaning my God is an oath or my God is abundance. The name Isabel spread widely through medieval Europe as a Spanish and Portuguese adaptation of Elizabeth, carried in part by royal bearers across France, England, and the Iberian Peninsula. Issy functions as an affectionate short form and is used independently in English-speaking countries. Related forms include Izzy, Isy, Isabel, Isabelle, and Elizabeth.
