Derani diphthong reform
When writing Derani, we could get rid of the diphthong mark (◌◌), and instead reuse more consonant glyphs to write falling diphthongs. This makes the writing system more compact and reduces the amount of marks underneath vowels.
| Official | Reform | Mnemonic |
|---|---|---|
| (aı) | ( aı / d) | "High" spiral |
| (ao) | ( ao / p) | (a) with a tail |
| (eı) | ( eı / z) | (e) with an (ı) flourish |
| (oı) | ( oı / nh) | "Low" spiral |
As a further mnemonic, the a diphthongs are both 9-shaped while the other two are ∂-shaped.
