I just had a thought about the whole "C" vs. "K" in terms of letters used for names. "C", though pronounced exactly the same as "K", has the connotation of being softer, at least to me, maybe because it can be changed into an "s" sound in English. "C" seems softer, smoother, and more elegant. "K" on the other hand seems more raw and powerful, and slightly harsher than "C". So it seems to me that Elvish, for example, should use "C" and Dwarvish, for example, should use "K".

I think that Tolkien thought, the same, because looking through wordlists on Ardalambion, you can see that except in primitive Elvish, which seems a much more to me a much more "raw" language, Elvish languages favour the letter "C" over "K". On the other hand, Khuzdul, Adûnaic, and the Orkish all use "K" instead of "C". As well as this, so does Valarin, which sounds like a very raw and powerful language.

The same goes with the "ch/kh" usage. Again, "ch" looks much more soft than "kh", which definately looks harsher, and we see a similar pattern. Tolkien gives "kh" and "ch" the same value, but I always imagine the "ch" to be a bit softer (going towards "gh", but still much more like "kh"), whereas the "kh" is pronounced harder. The sound "gh" is also related, as the other extreme (to "kh"), which is used in Orkish. "Kh" is used in Adûnaic and Khuzdul, and "ch" is used in Elvish. Valarin uses all three.

Just an idea.
