On the Procgenesis language generator, you find these five Phoneme types: C,V,L,S,& F. I believe that C and V are Consonants and Vowels respectively, but nothing I look at can explain the rest. The link is here: http://procgenesis.com/LanguageGen/langgen.html

  • Note that you should not assume that abstract symbols L, S, F in other sources (books etc.) have the same meaning as on that page. E.g. L could mean any Lateral consonant and S could mean any Sibilant consonant.

From a bit of experimentation, it seems:

L is liquids: consonants that can appear after a C in an onset.

S is starts: consonants that can appear before a C in an onset.

F is finals: consonants that can appear in a syllable coda.
