After doing all of this research, I am beginning to think that all
of these pronunciations are incorrect in regard to convention!
If Aleph is an 'uh' sound (gutteral swallow) and the other 'a' (the forearm) is pronounced as 'aiy' (as in the arabic 'ayn) then Ma'at should really be pronounced through modern convention as Muh-aiy.
I think that I'll just stick with 'Maht', and say it like they do on T.V. This argument really is quite pointless as modern convention is completely different from the original pronunciation (probably!).
For example the Egyptian king whose name is most accurately transcribed as "R?-mss" is known as "Rameses", even though cuneiform tablets that mention him suggest that a more accurate rendering with vowels would have been "Ri`amasesa".
In the wise words of the genius who was Sir Alan Gardiner:
It must never be forgotten that the vocalizations thus provided are purely artificial makeshifts and bear little or no relation, so far as the vowels are concerned, to the unknown original pronunciations as heard and spoken by the Egyptians themselves. [p. 28]
P.S Thoth is obviously god of the moon, who doubted it? As a baboon he almost always wears the lunar disk and crescent moon. He was shown as a baboon supposeedly because their serious expressions made them look wise.
Thoth is one of the coolest gods, but I still say Thoath (like 'oath') rather that Thoth (like 'goth'), as most Egyptologists on T.V say that, and so does the Oxford English Dictionary.
