Cuneiform nine, ilimmu₄ form

It records nine in a particular cuneiform numeral form. Sign lists identify this form as 9(diš)@v, read as ilimmu₄. On a tablet, read the amount with its unit or object; the sign alone does not tell you what was counted. Writing it as plain “9” keeps the amount but loses the source’s exact cuneiform sign choice.

Why was this nine sign used?

It served record keeping. Mesopotamian writing is attested in administrative accounting around 3300 BCE: numerical marks recorded goods as cities and states expanded, and those marks developed into wedge-impressed cuneiform. During the Early Dynastic and Ur III periods, scribes used different systems to measure land, grain, containers, livestock, and other goods. At Malyan, a sign-list entry identifies ILIMMU4 as a variant of GAH, another cuneiform sign.

Why do cuneiform nines have different forms?

Period, writing style, and sign lists preserve distinctions. Digital cuneiform guidance describes different wedge-stacking patterns for the same 9(diš) value. Some Ur III texts distinguish related variant families for scratch calculations and their results. Fonts can also arrange the wedges differently while preserving this encoded character.
