Demotic means "popular". It was the popular style of writing at the time.

Demotic refers to either the ancient Egyptian script derived from northern forms of hieratic used in the Delta, or the stage of the Egyptian language following Late Egyptian and preceding Coptic. The term was first used by the Greek historian Herodotus to distinguish it from hieratic and hieroglyphic scripts. By convention, the word "Demotic" is capitalized in order to distinguish it from demotic Greek.
