LANGUAGE

One Sign, One Sound

History · Bronze Age · Holocene · Meghalayan

Writing was invented by scribes, but the alphabet was invented by workers: Semitic-speaking labourers in the mines of Sinai, then ruled by Egypt, borrowed a set of Egyptian signs around the nineteenth century BCE and gave each one the first sound of its name in their own language. Where cuneiform and hieroglyphs demanded hundreds of signs and years of schooling, this system needed a couple of dozen. Through Phoenician traders it seeded nearly every alphabet now written.

Why it matters

The alphabet democratised what writing had monopolised: with so few signs, literacy could escape the scribal class, and eventually did. Latin, Greek, Cyrillic, Arabic, Hebrew and hundreds of other scripts all descend from that one invention. The letters on this page are the direct heirs of marks scratched by miners four thousand years ago.

Dating & uncertainty

The earliest alphabetic inscriptions were carved at Serabit el-Khadim in Sinai, around the nineteenth century BCE, by Semitic-speaking workers who borrowed Egyptian signs for their sounds; the inscriptions at Wadi el-Hol in Egypt are younger. From this single invention descend, through Phoenician, the Greek, Latin, Arabic, Hebrew and most other alphabets on Earth.
