Acrophony in the context of "History of the alphabet"

Alphabetic writing – where letters generally correspond to individual sounds in a language (phonemes), as opposed to having symbols for syllables or words – was likely invented once in human history. The Proto-Sinaitic script emerged during the 2nd millennium BC among a community of West Semitic laborers in the Sinai Peninsula. Exposed to the idea of writing through the complex system of Egyptian hieroglyphs, their script instead wrote their native Canaanite language. With the possible exception of hangul in Korea, all later alphabets used throughout the world either descend directly from the Proto-Sinaitic script, or were directly inspired by it. It has been conjectured that the community selected a small number of those commonly seen in their surroundings to describe the sounds, as opposed to the semantic values of their own languages. This script was partly influenced by hieratic, an older cursive script derived from hieroglyphs. Mainly through the Phoenician alphabet that descended from Proto-Semitic, alphabetic writing spread throughout West and South Asia, North Africa, and Europe during the 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, in turn derives from the Etruscan and Greek alphabets, themselves derived from Phoenician.
