The
Vulcan Language Dictionary has compiled a lot of Vulcan words and the
The Star Trek Online Geekipedia has a whole section on Vulcan language too, but both use transcriptions with Latin letters, which may be practical for fic, but doesn't work for fanart (like when you want to draw a Vulcan inscription or such).
I also looked at the entry for
Vulcan language on Memory Alpha, and that shows several script samples, both calligraphy (the vertical ones with the curves arranged along a line) and print (which look like very different squiggles), but no indication what the samples shown mean (probably because in a Doylist context they don't actually mean anything besides a concept artist/set designer thinking "this looks pretty and alien" but I'm a firm Watsonian by inclination and look for meaning *g*).
The only symbols I found the meaning of was characters often visible on Vulcan robes, according to
this prop sale blog article about Vulcan symbols and clothing those are called Rata, Tafar and Tapan (for Concept, Discipline and Process respectively). So that seems to indicate that the Vulcan script is not an alphabet, though I guess an argument could be made that in the context of decoration with a fixed set, something that usually is just a letter can come to mean a word.
Are there any other sources with information about the Vulcan scripts, and more examples?
Related, I'd be interested if there exists more general information about meaningful symbols in Vulcan decorative arts. The IDIC symbol is of course well known, but are there any others we know of? Like representing other philosophical concepts, or do for example the families/clans have something like crests/coat of arms symbolizing them? The rank symbols on their uniforms? (I've seen on memory alpha a picture of a Vulcan captain's pin from the 20th century, but no systematic overview showing several ranks.) Are any of these known?
