oh gosh, this looks way more complicated on the screen than it does on paper...

(this is the table of endings for verbs, which indicate Evidentiality and Epistemic Modality)

(in this thread, any words that I put with a Capital letter at the start are ones that you can look up on wikipedia and get a fairly understandable explanation)

the – before the letters just means that it's a suffix (they're all suffixes)

following that is the optional vowel. This vowel is inserted in between the verb and the rest of the suffix, but ONLY if the vowel's absence would break the pronounciation rules.

Each of the optional vowels has an acute accent above it, which means that it is associated with a high tone. Any vowels without an accent above them have a low tone.

after the optional vowel comes the actual suffix, which (with the exception of the "surprised but believe it's true" form of the Reported evidential ending) is a consonant cluster.

tɬ and ʈʂ are single consonants rather than 2 (voiecless alveolar lateral affricate and voiceless retroflex affricate)
