@MMS re: 'Yahawashi'. I've heard it explained that "paleo- Hebrew" only had certain (unwritten) vowels. The full range of vowels you hear in modern Hebrew is the result of reconstructing a dead language and infusing it with new (German/ Yiddish?) vowels.
I wonder how the Yemenite Jews pronounce it.
They have been described as "the most Jewish of all Jews" and
"the ones who have preserved the Hebrew language the best".[9]
Every Yemenite Jew knew how to read from the Torah Scroll with the correct pronunciation and tune, exactly right in every detail. Each man who was called up to the Torah read his section by himself.
All this was possible because children right from the start learned to read without any vowels. Their diction is much more correct than the Sephardic and Ashkenazic dialect. The results of their education are outstanding, for example if someone is speaking with his neighbor and needs to quote a verse from the Bible, he speaks it out by heart, without pause or effort, with its melody.
