But unlike Arabic, this does not mean that the vowel diacritic can be dropped. It cannot, as there 8 vowels and not 3. Vowel "à" (◌ࣵ) does not have a long version.
The main distinction between this writing system and Arabic lies in the fact that vowel diacritics cannot be omitted here, unlike in Arabic. This is because there are eight vowels available for use, as opposed to the three found in Arabic.
