The highlighted sounds are the inventory. The one in light green is technically in the language, but it's considered a "squished" pronunciation of /i/. They also have a back-of-the-throat hiss that's used as a swear or exclamation.

By "squished", do you mean like the u in Japanese suki?
The first thing I'd ask is "Does the language have [j], at least phonetically?" If so, it would match French, which has only /ɲ j/ for palatals, and /j/ often alternates with /i/. French originally had /ʎ/ as well, but it merged into /j/.LittleLynx_53 wrote: ↑04 Apr 2022 20:49The single palatal consonant will probably get a history added to explain it now that you've pointed that out. Would you think it would be more likely for it to be the only survivor of a sound change where the other palatals were lost, or picked up from another language?
I do not think it has /j/ as a separate phoneme. It may have it as an allophone of /ɲ/ or as a combination like /ɲj/ (to make it more distinguishable from /n/.Dormouse559 wrote: ↑05 Apr 2022 00:46The first thing I'd ask is "Does the language have [j], at least phonetically?"

To go on an approximant tangent, does the language have /w/? I noticed it isn't included in your consonant chart.
