Alphabets are the greatest achievement of humanity; They kept the civilization going on by recording the knowledge of each nation. Going from drawing symbols and shapes on the walls to the written letters was a great leap for humankind.
An alphabet is a standard set of basic written symbols that represent the phonemes (basic set of sounds) of any spoken language it is used to write.
The history of writing the alphabet can be dated back to the consonantal writing system; this system was used for Semitic languages in the Levant in the 2nd millennium BCE.
