Changes in Pre-Egyptian vocalism

Lately I've been reflecting on what Loprieno says about the early Egyptian vowel system on page 55 of Ancient Egyptian: A linguistic introduction (1995):

"In our discussion of phonology (section 3.4.3), we saw that one of the major features of Egyptian in its early stages was the presence of a strong expiratory stress, which eventually caused a reduction to /ø/ of short vowels in open syllables in posttonic position, with the resulting change from the Dreisilbengesetz to the Zweisilbengesetz (**saḏimat > *saḏmat 'she who hears')."

While Loprieno speaks of reduction to zero, I've long been thinking more along the lines of a Pre-Egyptian system of *a, *i and *u being reduced to *schwa* wholesale in all unstressed positions. To begin with, long vowels were only to be found in stressed positions in Pre-Egyptian, at least if the comparison with Proto-Semitic is trustworthy, and this length contrast in stressed positions clearly remained in Egyptian, as still evidenced by Coptic. I therefore choose to write all of these reduced, unstressed monophthongs of Pre-Egyptian as *a (to be implicitly understood as [ə]). Furthermore diphthongs *Vy and *Vw (*V = any vowel) then become *i [əj] and *u [əw] respectively. This has worked very well for me for a while now. The result is an Egyptian vowel system that still looks on the surface much like Proto-Semitic with long vowels restricted to stressed syllables and unstressed positions having only short *a, *i and *u. Yet since the system has been notably altered, we find a curious incongruence nonetheless between the vowels of Proto-Semitic and those of Egyptian.

We can also avoid a lot of the wildcard symbols Loprieno and others occasionally use in the unstressed syllables this way since my theory makes this pointless: Only *a can exist in these positions unless accompanied by a written semivowel y or w in which case the appropriate short high vowel is selected. It appears that the matter of whatever the original vocalism may be is an issue for Pre-Egyptian reconstruction, not Egyptian proper. Loprieno's */'ri:ʕuw/ (> */'ri:ʕə/) 'sun' becomes my *rīˁa.

There are further reasons why I'm dwelling on this, but I've divided it up into subsequent posts.

Theft is big business

BBC News informs us of the frustratingly inevitable plundering that occurred in yet another country in arms: Libya's historic treasures survive the revolution.

One may start suspecting a regular, enduring theme of events given Egypt's looting under the watch of Zahi Hawass (who was unsettlingly connected with the Mubarak regime at home, mind you) and Iraq's looting of Babylonian artifacts during the Iraq war. Regardless of why it keeps occurring lately, the world loses one more piece of its soul as we stand by and simply allow our collective history to be sold for a cheap buck.
