Hieroglyphs, hieratic and Demotic write consonants only. That is why Egyptologists add e between consonants to say words aloud: nfr is said "nefer" by convention. Coptic, with its full set of vowel letters, is the first stage of the language to show how words actually sounded.
Key idea
Because Coptic writes vowels, it shows how Egyptian words sounded late in their history: rn "name" is ⲣⲁⲛ, ran; nfr "good" is ⲛⲟⲩϥⲉ, noufe. But Coptic shows the sounds of the first millennium AD, not the sounds of the pyramid age.
Why it works
Every spoken language changes, and three thousand years is a long time: compare the English of today with that of a thousand years ago. Some Egyptian consonants disappeared (the r at the end of nṯr "god" is gone in ⲛⲟⲩⲧⲉ, noute), some changed (the ḫ of ḫpr became the sh of ϣⲱⲡⲉ), and the vowels moved. So Coptic is excellent evidence for late Egyptian sound, and only indirect evidence for earlier sound.
| Egyptian | Convention | Coptic | Sound in Coptic | Change |
|---|---|---|---|---|
| rn | ren | ⲣⲁⲛ | ran | the vowel shows: a |
| nfr | nefer | ⲛⲟⲩϥⲉ | noufe | final r lost |
| nṯr | netjer | ⲛⲟⲩⲧⲉ | noute | ṯ became t; final r lost |
| ḫpr | kheper | ϣⲱⲡⲉ | shōpe | ḫ became sh; final r lost |
| mw | mu | ⲙⲟⲟⲩ | mou | the w is written ⲟⲩ |
| rꜥ | Ra | ⲣⲏ | rē | ꜥ lost; the vowel is ē |
Worked example: Hearing a word
How was ꜥnḫ "life" pronounced in Coptic times? Its Coptic form is ⲱⲛϩ.
- ⲱ = ō, ⲛ = n, ϩ = h.
- So: ōnh. The ꜥ left no trace, and ḫ became h.
- The familiar "ankh" is a modern convention, not the Coptic sound.
Answer: ōnh.
Worked example: Earlier evidence
Can Coptic tell us exactly how Khufu's builders said nfr?
- No. Coptic ⲛⲟⲩϥⲉ shows the word about 2,500 years after Khufu.
- Earlier evidence exists in a few places, such as Egyptian names spelled in cuneiform letters of the New Kingdom (Ramesses II's name appears in Hittite records as Riamašeša), but it is patchy.
- So vowels before Coptic are reconstructed with real uncertainty.
Answer: No: it shows only the late pronunciation.
Dialects add a further layer: the same word can have different vowels in Sahidic and Bohairic, as you will see in the next topic.
Common mistake
Applying Coptic vowels to Old Egyptian. Pronunciation changed over three thousand years. Use Coptic as evidence for late Egyptian sound, and treat earlier vowels as uncertain.
