The phonology as currently written says that /j/ does sometimes undergo fortition towards a voiced fricative, but mostly in onset position and especially word initially, not as a coda. As for /χ/... the language has both /k/ and /q/, but only one back fricative that I had considered to cover the range x~χ. Assuming that the fricatives are partly the product of some kind of lenition process, which would be required for a synchronic k~x/k~f alternation anyway, you could imagine q->χ and a more inconsistent k->x->χ, OR k->x->f.bradrn wrote: ↑Sat Jan 21, 2023 5:49 pmI think they’re both equally distinctive. [χ] and [ʃ] already feel very far away to me, and [χ] and [j] even further apart. But really, I think it all depends on how your language structures its consonants — e.g. in Hebrew they’d be straightforwardly different, whereas in Spanish (where [j~ʝ] can merge into [ʒ] and [x] can be velar) they might be considered a lot more similar. I recall Nortaneous talking about the fact that which phonemes ‘choose’ to interact with which others can be quite different between languages; something similar applies here, I think.chris_notts wrote: ↑Sat Jan 21, 2023 12:58 pm So which set of consonants do you think is most distinctive in coda position mid-word, {j, N, χ, 0} or {j, N, f, 0}?
I think I'll probably go with /f/ for now. With more complex agglutinative morphologies I always worry about accidentally creating too much ambiguity or too little distinctiveness... aside from questions like this that concern distinctions within a given TAM... cluster, I've also written some Python scripts to compile all the possible forms and then identify the most similar / ambiguous pairs that cross sub-paradigms. A lot I'm happy with, e.g. the following differing by only 1 phoneme in some cases seem fine:
Independent Imperfective ~ Subordinate Imperfective (addition of subordinate n- in many cases)
Independent Perfective ~ Subordinate Perfective (addition of subordinate n- in many cases)
Subordinate Perfective ~ Subordinate Imperfective (contraction of nu-ta -> na means it's na- vs nu- in many cases)
A few others feel like they should be more distinct, so I've adjusted them a bit. In general I'm more concerned where the meaning is very different and the 1 phoneme difference is buried far inside then when it's in a prominent position (e.g. word-initially).
I guess I'm overthinking things, but it's one struggle I have with highly synthetic conlangs that I haven't been able to shake even after >20 years of conlanging.
