Iza

Iza is a short form, most often of Izabela, and it reaches back through Hebrew to Elisheva, the source of the meaning my god is an oath. In Polish that comes out as bóg jest moją przysięgą, a promise sworn and then worn as a name. The gloss stays simple.

Alongside Iza runs Izolda, listed here as a variant. It shares the opening sound while leaning toward the medieval Tristan legend rather than the Hebrew oath, so the two names travel together by ear more than by root.

Written out, Iza takes only two syllables, enough to fill a line on a class register or the front of an imieniny card. Girls who carry it have made it ordinary and easy, a household short form with a solemn origin behind it. That origin holds: an oath, and the God it names.
