<P> The history of alphabetic writing goes back to the consonantal writing system used for Semitic languages in the Levant in the 2nd millennium BCE . Most or nearly all alphabetic scripts used throughout the world today ultimately go back to this Semitic proto - alphabet . Its first origins can be traced back to a Proto - Sinaitic script developed in Ancient Egypt to represent the language of Semitic - speaking workers in Egypt . This script was partly influenced by the older Egyptian hieratic, a cursive script related to Egyptian hieroglyphs . </P> <P> Mainly through Phoenician and Aramaic, two closely related members of the Semitic family of scripts that were in use during the early first millennium BCE, the Semitic alphabet became the ancestor of multiple writing systems across the Middle East, Europe, northern Africa and South Asia . </P> <P> Some modern authors distinguish between consonantal scripts of the Semitic type, called "abjads", and "true alphabets" in the narrow sense, the distinguishing criterion being that true alphabets consistently assign letters to both consonants and vowels on an equal basis, while in an abjad each symbol usually stands for a consonant . In this sense, the first true alphabet was the Greek alphabet, which was adapted from the Phoenician . Latin, the most widely used alphabet today, in turn derives from Greek (by way of Cumae and the Etruscans). </P> <P> Two scripts are well attested from before the end of the fourth millennium BCE: Mesopotamian cuneiform and Egyptian hieroglyphs . Hieroglyphs were employed in three ways in Ancient Egyptian texts: as logograms (ideograms) that represent a word denoting an object pictorially depicted by the hieroglyph; more commonly as phonograms writing a sound or sequence of sounds; and as determinatives (which provide clues to meaning without directly writing sounds). Since vowels were mostly unwritten, the hieroglyphs which indicated a single consonant could have been used as a consonantal alphabet (or "abjad"). This was not done when writing the Egyptian language, but seems to have been a significant influence on the creation of the first alphabet (used to write a Semitic language). All subsequent alphabets around the world have either descended from this first Semitic alphabet, or have been inspired by one of its descendants (i.e. "stimulus diffusion"), with the possible exception of the Meroitic alphabet, a 3rd - century BCE adaptation of hieroglyphs in Nubia to the south of Egypt . The Rongorongo script of Easter Island may also be an independently invented alphabet, but too little is known of it to be certain . </P>
