From left field.
Say, no wonder... that player in left field is Y.
Same as the one letter in E-G-Y-P-T that doesn't get along with any of the others. It simply doesn't not rhyme.
If you follow Egypt's etym. trail, you can see that the glyph in the middle is similarly shaped. It's the hands raised in the air with a vertical line underneath to signify that it's an ideograph. In this case representing the very power/life force (ka) of Egypt's creator god Ptah.
Even the name Ptah is spelled the same in Hebrew as the word for an opening, doorway [פתח]. It's the root from which "key" derives.
I mention this because the "Y" glyph is also the image of the meaning of the name Judah: to praise, of casting the hands up into the air.
Which of course loops right back to the very identity of the Jews -- the question-asking people, as Moses in Exo 3:3.
Pharaoh showed Moses the door.
"There's the door!"
Then, when all of the Ys left Egypt, it was lights out for EGPT just on the simple principle of the word.
The Dark Side never learns!
Interesting. The meru foundation (meru.org) did a lot of work on the Hebrew alphabet. Stan Tennen the founder passed a year ago, but over his decades he produced a lot of thought provoking content for those of the mindset to investigate such thoughts. The content is still online.
Some of the things they did was to create 3D “ribbons” of Hebrew letters. Then you shine a light through the letters at various angles, it would project onto the wall and reveal all new designs. Some of which would of course look like double helix DNA strands and the like. And much more. One would have to be well versed to truly analyze and make connections like the one you posted about the Y in Egypt but that is, imo, the point. The more you learn the more is revealed to you as long as you remain truly open to seeing revelations.
In short, each letter would project new meaning into the world depending on how you looked at it. Or as the sages would say “there are 70 faces to the Torah”. You could spend a lifetime and not see them all. But one could try.
