Iza is believed to have originated from the Hebrew name Elizabeth, which means 'God is my oath'. It is often considered a diminutive of Isabella or Isabel, both of which derive from the same Hebrew root and mean 'devoted to God'. The name Iza gained popularity in Poland during the Middle Ages. It has since been used in other Slavic countries and beyond, but remains relatively uncommon outside of these regions. Iza is typically pronounced /'ɪzə/ or /'iːzə/, with the stress on the first syllable. There are no significant variations of this name, though Izabela (Polish) and Izabella (Hungarian) could be considered related names.
