Ḍa (also romanized as Dda) is a consonant of Indic abugidas. In modern Indic scripts, Ḍa is derived from the early "Ashoka" Brahmi letter after having gone through the Gupta letter . As with the other cerebral consonants, ḍa is not found in most scripts for Tai, Sino-Tibetan, and other non-Indic languages, except for a few scripts, which retain these letters for transcribing Sanskrit religious terms.
