Luwian Hieroglyphs are otherwise known as Hittite Hieroglyphs. The name Luwian comes from the three glyphs shown in the image. This is how they referred to themselves. The first glyph is unidentified but is associated with the sound La. The second is called mountain or the Mons glyph in Latin. It has the associated sound Wa. The third is also unidentified but has the sound A. Hence, the name is La-wa-a.
Sometimes the sound attached to the glyph is not used but the name of the glyph is used as in a rebus. In other words, it is also possible they referred to themselves by the identity of the glyphs.
I would like to suggest the following revisions for these symbols. The first glyph is an image of the “Primary Line of Longitude.” La or ley is still an appropriate sound to be attached to it. The second glyph is not a mountain but a set of dividers which is a tool used in navigation and engineering to transfer measures. The symbol shows an angle. Its name should be Ing or Ang for angle. The sound wa is still appropriate since Hittite is an Indo-European language and wa means woe. The word angst has the root word ang and also means woe. The third glyph is appropriately associated with the sound a. I believe it shows a knife, sword or dagger.
The symbols might be translated to mean ”Measurers of Angle with respect to the Line” and their name to La Ang-a as opposed to Luwian. It is not a big leap to their modern name. This begins to explain the origin of the name Angle or English which is poorly understood today.
This is too brief to give a real explanation. The next series of posts, although they seem unrelated at first, will eventually lead back to this very subject of Luwian or should we say Angle.
