Thaana Letter Ttaa
Thaana is the modern writing system of the Divehi language spoken in the Maldives. Thaana has characteristics of both an abugida (diacritic, vowel-killer strokes) and a true alphabet (all vowels are written), with consonants derived from indigenous and Arabic numerals, and vowels derived from the vowel diacritics of the Arabic abjad. Its orthography is largely phonemic. Thaana, like Arabic, is written right to left. It indicates vowels with diacritic marks derived from Arabic. Each letter must carry either a vowel or a sukun (which indicates “no vowel”). - Wikipedia
