Alphabets evolved from pictographs and ideograms, which are symbols that represent an object or idea and are not exactly specific to a language. The alphabet is a writing system that uses symbols to represent sounds and they tend to be specific to a language. One of the first alphabets developed was the Phoenician alphabet, which dates back to 1000 B.C.E from inscriptions in the Phoenician city of Byblos. The Phoenician alphabet evolved from the “proto-Canaanite” alphabet, which was a system created around the 18th century BCE. It is also said to be an advancement of Egyptian hieroglyphs, since the Phoenician system can be found in some Egyptian hieroglyphs. The alphabet evolved in about 1250 BCE and it is classified as “acrophonic”, the idea that the name of the letter derives from a word that starts with that letter.
