I know exactly what I'm doing to myself. I'm comparing my first stabs with Quenya and Sindarin and Proto-Eastern and my vision of what it all ought to look like, and naturally my first stabs are coming out at the wrong ends of those comparisons. So screw it. It'll look OK, and that's all I can ask for. You'll note I've given up on the idea of having a lot of consonants in one chunk of the space, but I care not.
Stops: p b, t d, t' d', k g
Fricatives: f, þ (or th, if you lack thorn), s, s'
Approximates, liquids and semivowels: m n n' l r w y
Those marked with apostrophes are retroflex, which is a phonemic distinction. In the fricatives, voicedness is not phonemic, but I will be spelling the voiced allophones with v, ð (dh), z and z' to aid pronunciation.
Stop, Fricative, Liquid, Vowel, Consonant. Roots look like (C)VC(VC); those roots lacking the initial consonant are always VCVC. C can be any single consonant initially, any consonant but w or y finally, or a cluster. Initial clusters can be sF, FS, FL, FSL, SL; medial and final clusters can be SL or FL except that w and y cannot appear word-finally.
Vowels TBD.
