Here’s somethng to ponder. Forty years on, Egyptologists at the Oriental Institute at the University of Chicago, have completed, at least for now, a dictionary of Demotic Egyptian. Demotic paralleled hieroglyphics, being of the people, as the latter was the script used by royals.
Here’s the New York Times article New Demotic Dictionary Translates Lives of Ancient Egyptians and here’s the online dictionary.
The dictionary, like the OED, gives many examples of the use of words, together with potted cites, in case you want to follow up.
