Direction of writing is top to bottom, left to right. Each glyph has initial, medial and final forms. Final forms have a long descender, which serves as a word separator.
Several consonant glyphs are underdspecified between plain, plalatal or palatalised, and labialised consonants. Which sound is intended is indicated by the form of the following vowel.
As well as initial, medial and final forms, vowel glyphs also vary according to tone (high vs low) and plain, iotised and labialized variants. Iotised and labialised vowel glyphs do not indicate different vowel sounds, but indicate the required reading of the preceding consonant glyph. Rising tone is indicated by writing a low tone version of a vowel with a high tone version of the same vowel, and vice versa for falling tone.
The last row of the vowel chart, labelled ∅, contains glyphs that indicate that the preceding consonant is palatal/palatalised or labialised when there is no following vowel.
Pete later clarified his handwriting:
The rows in the first chart, of vowels, from top to bottom represent:
i (high tone)
i (low tone)
e (high tone)
e (low tone)
a (high tone)
a (low tone)
o (high tone)
o (low tone)
u (high tone)
u (low tone)
y (high tone)
y (low tone)
∅
Across the page, the three groups of columns represent the plain, labialized and iotized forms of the vowels, and within each group the three columns are initial, medial and final forms.
