More on the Egyptian Language

Language

Egyptian is in the Afro-Asiatic (Hamito-Semitic) Family.
So it is (distantly) related to the Semitic languages (Arabic, Hebrew, Aramaic, Akkadian, etc.).
Egyptian constitutes its own branch of the Afro-Asiatic family of languages.
Coptic is a later form of Egyptian. Coptic was spoken from about the 2nd to the 17th centuries (written until the 14th).
In fact, Coptic is still used today in religious ceremonies by Coptic Christians (Arabic speaking Monophysite Christians of Egypt).

Vowels in Egyptian probably shifted with grammatical inflection, which led to writing systems that did not indicate vowels.

Writings

First appears in the end of the predynastic times: 3100-3000 BC. (Slightly later than Sumerian writing).
First continuous texts from c. 2650 in the old kingdom.
Before Coptic, all writings were consonantal: nothing in the writing indicates the vowels. The vowels have to be guessed based on later Coptic forms and non-Egyptian contemporaries.

Egyptians thought writing was the invention of Thoth, god of learning and writing.

Hieroglyphic

Hieroglyphics had a cursive form used, instead of hieratic, on papyrus for things like the book of the dead or coffin texts. Last known AD 394. About 6000 in the course of time, but many of these are not common and arose in the late period (after about 600 BC). Only 700 in the middle kingdom, but much fewer are common. From the Greek hierogluphiká meaning "sacred carvings". Often written in vertical columns, but horizontal lines occur. Right to left is most common, but left to right when appropriate to the composition. The direction is consistent with how the characters are facing: if the characters face right the characters are read from right to left. Three types of characters (i) logogram which signified a whole word, (ii) phonogram which signified a consonant or consonant cluster, and (iii) determinatives which aided in interpreting the meaning of the word. There were many logograms. The phonograms were borrowed from the logograms and had the phonetic value of the consonants in the word represented by the logogram (not just the initial consonant: rebus principle). Determinatives were placed at the end of the word. For example, the sign for mouth looks like a mouth. But this character could be as a phonogram. Since the word for mouth has only the consonant r, the character represented r. 26 phonograms had values of one consonant. 80 common phonograms had value equal to a cluster of two consonants. About 70 phonograms had value equal to a cluster of three consonants. There are a large number of determinatives which occur at the ends of words.

Hieratic

Hieratic. Cursive hieroglyphics. Always right to left. Seems to developed early alongside the more formal Hieroglyphs. Well attested in the Old Kingdom. Lasted until at least the first century AD. Uses ligatures. There are a variety of styles one of which developed into demotic. Name comes from greek because after dem. only priests used it. Columns were common at first read from top to bottom, and the columns read from right to left. Later horizontal lines (always right to left).

Demotic

Replaced hieratic around 600 BC except in religious writings.
Demotic evolved from hieratic in Lower Egypt.
Spread to all of Egypt in the 26th dynasty. Horizontal: right to left.
Was gradually replaced by Greek and Coptic. The last known example of demotic dates to about 450 AD.
Unlike hieratic, demotic was used in inscriptions as well as for papyrus.

Coptic

Coptic is essentially the Greek alphabet with six or seven signs added for sounds not found in Greek (sh, f, h, j, g??, ti). These signs come from Demotic. The script is truly alphabetic and goes from left to right. The term Coptic comes from Copt, which comes from Arabic Gubti, which comes from Greek Aiguptios. It was well established in the 4th century. Perhaps started out as magic texts where exact pronunciation was important. It was spread by Christians in Egypt. It continued to be used until at least the 14th century. It is still used in the Coptic Christian church (that is, the Arabic speaking Monophysite Christians of Egypt.).

Rosetta Stone

Black basalt. 762 kg. 1.18 meters high. 77 cm wide. 3 cm thick. Dates from 196 BC. Honors paid to Ptolomy V Epiphanes by the temples of Egypt. Napoleon's armies found it in 1799 and took it to Alexandria. After Napoleon's defeat, the British gained possession of it in 1801. It was taken to England in 1802, and it has been in the British Museum since 1802.

Decipherment

Coptic was able to be read before the Rosetta stone, but the older forms of writing were not. Many people contributed, or tried to contribute, to the decipherment of Egyptian writings, but two names stand out. Thomas Young (1773-1829), an Englishman, is famous for his work in physics. He describing light as a wave, in contradiction to Newton. He began working on the Rosetta stone in 1814, and in 1818 he published his findings as a supplement to the fourth edition of the Encyclopedia Brttannica. Jean-François Champollion (1790-1832), a Frenchman, started before 1822. He was fluent in Coptic before he deciphered the earlier writings. He published his initial findings in 1824 Précis du système hiéroglyphique.

Rosetta Stone

There is evidence that the Canaanite alphabet was formed by taking certain hieroglyphics, but giving them the phonetic value of the first consonant of the Semitic word corresponding to the character. Thus Hieroglyphics were the source of our alphabet.
