What is the Egyptian term for hieroglyphics

The Egyptians called hieroglyphics mdw nTr, which means “divine words.” Since vowels weren’t written, it’s hard to know exactly how this was pronounced. Capital ‘T’ represents a sort of ‘ch’ sound, and Egyptologists conventionally insert the vowel ‘e’ between consonants and treat ‘w’ as a ‘u’. Under this scheme the pronunciation is “medu netcher.”
