a system of written communication
Explanation:
Somewhere around 3000 BC, ancient Egyptian civilization developed the hieroglyphs – the written system of communication. It was a mature and complex writing system.
While this was not the first alphabetic system ever, it is very important for later understanding of the culture and history of Egypt, as well as other civilizations. This graphic alphabet had over 800 symbols and was used for all the scripts – from political and religious, to everyday writings of the people.
