The first Letters were invented nearly four thousand years ago (between 1800 and 1900 BC).
Scholars attribute its origin to a little known Proto-Sinatic, Semitic form of writing developed in Egypt between 1800 and 1900 BC. Building on this ancient foundation, the first widely used alphabet was developed by the Phoenicians about seven hundred years later.
By at least the 8th century BCE the Greeks borrowed the Phoenician alphabet and adapted it to their own language, creating in the process the first “true” alphabet, in which vowels were accorded equal status with consonants.
