Cuneiform Sign Za

Its value changes with the language and surrounding signs. The cuneiform sign ZA can record syllabic readings such as za or ṣa, or stand for a whole Sumerian word. The language and neighboring signs determine which use fits.

Cuneiform began in southern Mesopotamia as clay administrative records in the late fourth millennium BCE. Signs shifted from pictorial marks toward wedge impressions, and the system later served Sumerian, Akkadian, and other languages. Inventories from the Early Dynastic period, an early era in Mesopotamian history, include ZA in compounds; later sign lists also record it on its own.

Why do ZA, za, and ṣa refer to one sign?

ZA names the sign; za or ṣa records a reading. In scholarly transcription, sign names are written in capitals. Lowercase za or ṣa gives a syllabic reading; ṣ marks an emphatic s sound. Capitals can also mark a logogram, a sign standing for a whole Sumerian word, so the surrounding text still matters.

In the Amarna letters, diplomatic messages from the fourteenth century BCE, the sign spells za inside the Akkadian word ḫa-za-nu, meaning a local mayor or royal representative.
