Meaning and history
Issy is an English diminutive used for several names, including Isabel, Isobel, Isaac, Isidore, and occasionally Isaiah. These sources have different meanings: Isabel belongs to the Elizabeth family, “my God is an oath,” while Isaac means “he will laugh” and Isidore means “gift of Isis.” Issy therefore has no single universal etymology. Notable bearers include British actor and singer Issy van Randwyck and English cricketer Issy Wong.
