The history of the alphabet goes back to the consonantal writing system used to write Semitic languages in the Levant during the 2nd millennium BC. Nearly all alphabetic scripts used throughout the world today ultimately go back to this Semitic script.[1] Its origins can be traced to the Proto-Sinaitic script that represented the language of Semitic-speaking workers and slaves in Egypt.[2] Unskilled in the complex hieroglyphic system used to write the Egyptian language, which required a large number of pictograms, they selected a small number of those commonly seen in their surroundings to describe the sounds, as opposed to the semantic values, of their own Canaanite language.[3][4] This script was partly influenced by the older Egyptian hieratic, a cursive script related to Egyptian hieroglyphs.[5][6] The Semitic alphabet became the ancestor of multiple writing systems across the Middle East, Europe, northern Africa, and South Asia, mainly through Phoenician and the closely related Paleo-Hebrew alphabet, and later Aramaic (derived from the Phoenician alphabet) and the Nabatean—derived from the Aramaic alphabet and developed into the Arabic alphabet—five closely related members of the Semitic family of scripts that were in use during the early 1st millennium BC.
Some modern authors distinguish between consonantal alphabets, with the term abjad coined for them in 1996, and true alphabets with letters for both consonants and vowels. In this narrower sense, the first true alphabet would be the Greek alphabet, which was adapted from the Phoenician alphabet. Many linguists are skeptical of the value of wholly separating the two categories. Latin, the most widely used alphabet today,[7] in turn derives from the Etruscan and Greek alphabets, themselves derived from Phoenician.
