How this cuneiform translator works

This tool has two tabs. Each one does a specific job, and both run in your browser without sign-up.

Tab 1 – Name, Text & Number Scribe. You type a modern name, a word, a sentence or a number. The engine splits every word into syllables using the Maximal Onset principle, which gives each syllable as many starting consonants as the language allows. It then maps each syllable to a cuneiform sign. The system uses the four-vowel set a / e / i / u that Sumerian and Akkadian scribes used. Sumerian logograms such as LUGAL (king) and DINGIR (god) are recognized as whole words. Numbers are written in the Babylonian base-60 positional system, so 123 becomes two sixties and three units, and 2026 becomes thirty-three sixties and forty-six units. Under each sign you see its ancient meaning. One click copies the whole line as a Unicode string, with an optional 𒑰 word divider. One more click prints an A4 PDF clay tablet.

Tab 2 – Complete 1,038 Cuneiform Signs Catalog. This is an encyclopedia of every official Unicode cuneiform sign in the block U+12000–U+1247F. The signs are sorted into 10 themed categories: gods and astronomy, kings and law, temples and cities, people, body and speech, animals, nature, crafts and weapons, numbers and measures, and grammar and function signs. Click a sign, or open a direct #U12xxx link, and a card shows the Unicode code point, the Microsoft Word shortcut (for example 1202D + Alt + X), the HTML entity codes, the 800×800 vector SVG and the historical description. From the same card you can print an A4 poster in Solid mode or in Outline mode for coloring, stencils and lessons.

Sumerian and Akkadian syllabary rules

Cuneiform is not an alphabet. It is a mixed system of logograms (one sign, one word) and syllabograms (one sign, one syllable such as ba, ni, ur). Sumerian was a language isolate with no known relatives. Around 2500 BCE the Akkadians, who spoke a Semitic language, borrowed the script and repurposed the signs for their own sounds. Babylonian and Assyrian are the later southern and northern dialects of Akkadian, and they kept using the same sign inventory for about two thousand years.

This has practical consequences for modern names. Sumerian and Akkadian phonology had only four vowels (a, e, i, u) and no separate signs for the vowel sound [o] or consonants such as [f], [v], [dʒ] or [w]. Writing a modern name like Olivia in cuneiform is therefore an approximate phonetic adaptation using the closest available Mesopotamian syllables, and closed syllables like gal or lug use a single CVC sign when one exists. Some syllable sounds have several signs, which scholars distinguish with index numbers such as sha6 or gu7, and the scribe engine maps each adapted syllable to those standard sign-list readings.

Spelling in Sumerian also followed context. A scribe could write a god's name with the DINGIR determinative, a small star sign placed before the name to mark it as divine. The tool treats DINGIR and LUGAL as whole-word logograms for this reason, instead of spelling them syllable by syllable.

Clay physics versus digital storage

The earliest writing appeared in Uruk around 3200 BCE (the Uruk IV period). It grew out of clay tokens and sealed clay envelopes called bullae, used to count barley (ŠE) and sheep (UDU). Scribes soon pressed the same marks directly into a flat clay tablet. They cut a reed (Phragmites australis) to a wedge-shaped tip, and the Latin word cuneus, meaning wedge, gave the script its name. Pictograms were turned ninety degrees and simplified into strokes made of wedges and the corner-shaped Winkelhaken.

Clay is remarkably durable. A tablet baked in a fire, or by accident when a city burned, survives for thousands of years. Ashurbanipal's library in Nineveh was destroyed in 612 BCE, and the fire hardened tens of thousands of tablets that scholars read today. A kiln firing at roughly 700–900 °C turns soft clay into ceramic.

Compare that to modern storage. NAND flash keeps data by trapping electrons in a floating gate through quantum tunneling, and the charge slowly leaks. Cloud files last as long as the subscription is paid. A clay tablet needs neither electricity nor a monthly invoice. If you want your name to last, printing it on paper is a decent compromise, and baking it is better.

Unicode, the SMP and the Word Alt+X shortcut

Cuneiform sits in the Supplementary Multilingual Plane (Plane 1), starting at U+12000. Because it is above the 16-bit Basic Multilingual Plane limit (U+FFFF), UTF-16 stores each sign as a two-unit surrogate pair: the first sign, U+12000, is encoded as 0xD808 0xDC00. Standard Alt+Numpad keystrokes only accept 8-bit or 16-bit codes, which is why five-digit SMP characters require hex-to-Unicode conversion.

In Microsoft Word you can type a code and convert it directly. Type the hexadecimal code point, for example 1202D, then press Alt + X, and Word replaces the text with the sign 𒀭. The catalog card for each sign shows this exact shortcut so you can copy it. If you only see empty squares (□□□, often called tofu), the font does not contain cuneiform glyphs. Install a font such as Noto Sans Cuneiform, or use the SVG version that this tool provides, which displays correctly on any device with no font at all.

Printable A4 sheets, outline contours and vector SVG

On screen the signs are always shown as clear solid shapes. When you print, you choose the style. Solid gives a dark clay-tablet look. Outline gives thin contours with empty interiors, which is useful as a coloring sheet for children, a stencil, a handwriting model for a history lesson or a template for engraving and calligraphy. Both styles use the same 800×800 vector drawings, so lines stay sharp at any size, and A4 pages print without margins or interface elements.

A word of caution about other tools. Many sites advertising a "cuneiform translator" simply map the letters A to Z onto 26 characters from Ugaritic or Old Persian, which are different scripts, then call the result Sumerian. Others require a registration or load megabytes of trackers to display a few wedges. Real cuneiform is syllabic, so a correct translation has to split words into syllables first. That is what this scribe does, and every output sign is traceable to the official Unicode sign list.
