More concern is in order for differentiation between the hard and soft sounds of the “B’gadhkephath” letters (תפכדגב). Some knowledge of their proper use has faded into history, especially letter ‘gimmel’, but Yahweh can restore it if he wants to – and we can help. For example, many modern Hebraists would pronounce Hebrew “thank you very much” as “todah rabbah”. A more classical rendition might sound more like “todhah ravvah”. Enjoy. Getting back to Ashkenazi tradition: the best guess is that in the restoration of all things, the “tau” in the word “shabbath” will be popularly used as a “th” again, as it was in times of old, instead of as an “s”, as in the traditional Ashkenazi “shabbas”.
The ‘A’ vowels could be differentiated a bit more consistently. ‘Pathach (ַ) should be a short ‘a’ sound, as in rap, tap, or cap. ‘Qames’ (ָ) should be a long ‘a’ sound as in ball, call, or fall. (North American English pronunciations)
Shurek (וּ) is a ‘u’ sound as in flute or sure, or ‘oo’ as in shoot or toot. Qibbuts (ֻ) is a shorter ‘u’ sound, as in put or sugar, or the ‘oo’ in look or hooky.
This information is usually substantiable from the older-fashioned Biblical or Classical Hebrew grammars such as Weingreen’s or Marks and Rogers, who wrote before ‘going with the flow’ became so fashionable.
So keep your ‘stick on the ice’, and your eyes on the word of Yahweh. It’s the trend for the future. Honest.
