The history of the alphabet goes back to a writing system for consonants. This was used for Semitic languages in the Levant in the 2nd millennium BC.[1]
By 2700 BC, the ancient Egyptians had developed a set of some 22 hieroglyphs to represent the consonants of their language. A 23rd seems to have been for word-initial or word-final vowels. The first purely alphabetic script may have been developed around 2000 BC for Semitic workers in central Egypt.[2]
Over the next 500 years, it spread north. All later alphabets around the world have either descended from it or been inspired by one of its descendants.[3][4]
