Wow, thanks very much! You've thought of a lot of stuff I hadn't at all. Fortunately, Togruta are almost identical in physical aspect to humans, and so any language of theirs would be fairly easy for a human to pronounce (or at least, no harder than any human language would be).
I had thought about making it tonal, but I have quite a problem with pronouncing tonal languages at speed, which would be necessary for me to really get to understand the language. I might have another go though. And clicks, I also included four clicks. I can't quite remember what they were, but I felt they weren't really in keeping with the rest of the phonology, so I removed them.
In my original version I think I included about twelve different trills, including the raised alveolar trill found in Czech, but it ended up becoming too dull to be interesting. Also, I think the bilabial trill has got to be one of the least attractive sounds in any language (that and /ʒ/!), so I tend to avoid it.
One thing which interested me (and this is where I show my incompetence!), is whether there is any human language which differs between phonemes by having them take tones. What I mean is, is there any natural language which could differentiate between an alveolar trill, say, spoken at a very high pitch, versus one at a more normal pitch? I included this, as well as 'high', or 'sung' alveolar lateral approximant, in my original version of Togruti. From what you've been saying though, I think I might reinstate it.
As for the grammar, I've created so many different versions of Togruti by now that I've used almost every form I can! At present I've got it as a slightly inflectional language with noun declensions for nominative, accusative, sociative, benefactive and vocative case. The pronoun system is relatively simple, and these also inflect to indicate various forms in a similar way to the nouns.
Another thing which I've used almost every possible form is with the writing system. Nowhere is Togruti ever shown written down, so I've got pretty much free reign to come up with something. I've used alphabets, syllabaries, alphasyllabaries, abjads, even phonologograms! But I want to make it interesting different from the ones on Earth, so I'm a bit stumped. I don't suppose you have any suggestions there?
Changing the subject now, I see you've only just joined the Omniglot forum. So welcome! Hopefully you'll find it as useful and inspirational as I have.
