Thaana Letter Ttaa

It represents Arabic ث in Dhivehi words written in Thaana.

Arabic ث usually has the unvoiced sound at the start of English thin, made with the tongue tip between the teeth. Dhivehi romanization writes ޘ as th' (scholarly transliteration: th); Persian spellings may use s. These notations point to the source consonant, not necessarily the pronunciation of a loanword in everyday Dhivehi.

ޘ appears in spellings of Arabic, Persian, and Urdu loanwords, especially Arabic personal names. It is a consonant base, so ordinary spelling adds a vowel mark or sukun, a mark showing that no vowel follows; ޘ alone is not a full syllable.

How did ޘ become part of Thaana?

Thaana grew through Dhivehi’s changing writing traditions.

Thaana’s emergence is estimated from the sixteenth to late seventeenth centuries. Samples on Kaditheemu doorposts are dated 1599 and 1611. Thaana appears alongside Dives Akuru in the 18th century and had replaced it by the turn of the 19th century.

Before Thaana, Dhivehi was written in Dives Akuru, a left-to-right script derived from Brahmi and related to medieval Sinhala. Thaana combines some consonant forms tied to numerals with Arabic-facing direction and vowel marks; ޘ belongs to its dotted extension for Arabic ث. Historical accounts connect early Thaana with fanḍita, a kind of spell writing, and Qur’anic quotations. Arabic compatibility is one proposed reason for the shift. The dotted system was formalized in 1957 to write Perso-Arabic words in Thaana. A Latin transcription briefly displaced Thaana for telex administration in the 1970s; Thaana later returned to everyday use.

Why does ޘ look different in text?

Thaana reads right to left, but ޘ does not join neighboring letters.

Numbers and embedded Latin text run left to right, so mixed text can appear to change direction. Thaana is non-cursive: its letters do not connect. Vowel marks attach to their consonant, and fonts may draw ޘ’s strokes differently.
