That runs into Kabbalaism... But, interesting information to chew on. Thanks for the link
No, it doesn't. The ideograms are a record of what the letter represented originally as a pictograph or hieroglyphic. Each letter also has an assigned number and meaning. They are also present in Phoenician, and in Greek. But the value in Greek or Phoenician is not expressive in the Judeo-Christian sense. That is only to be found in Hebrew.
For instance, the simplest meaning I could point to is the letter tav, whose ideogram is a perfect representation of a Christian cross, and whose meaning is "covenant."
Kabbalism has nothing to do with it.
