I was just looking through Hoch's SEMITIC WORDS IN EGYPTIAN TEXTS OF
THE NEW KINGDOM AND THIRD INTERMEDIATE PERIOD. What Mr. Vidal is
confused about is the fact that at this late stage of Egyptian Semitic
words with "l" were transcribed as Egyptian "r". However, Semitic "r"
was also transcribed as Egyptian "r". In a previous post, I showed the
Egyptian word "per" comes from proto-Afroasiatic *par . Cognates in
other Afroasiatic languages are all "r" and not "l".
It is easy to confuse this with the vulture symbol, which changed
from "r or l" to "a or e".
The word for house does not use the vulture symbol.
The Egyptian word for Pharoah was Per-aa, which literally means "big
house". However, this could be a rebus. There are Semitic words like
Par'oh meaning "prince". And, the similarity with Indo-European words
like "prince", Fürst, and "primus" is obvious.
