Ḍadda: The Gurmukhi Letter

Ḍadda is the eighteenth letter of the Gurmukhi painti and the third member of the retroflex series, the voiced unaspirated retroflex d. It stands to Ṭainka exactly as Gagga stands to Kakka and Jajja to Chachcha, adding voice to a closure already established, and the regularity of that relationship across all five series is what makes the painti a system rather than a sequence. Punjabi keeps Ḍadda distinct from the dental d written six letters further on, and the two are not interchangeable in any word. On the page the letter is a stem hung from the headline with a bowl to its right, and it is close enough in shape to two of its neighbours that clarity in handwriting matters.

None of the six dotted extensions added to Gurmukhi for Perso-Arabic sounds falls on the retroflex series, because retroflexion is the native feature of the language and it was the borrowings that had to be fitted to it. The regularity of the series is worth dwelling on because it is what allows the painti to be short. Five points of articulation multiplied by five manners gives twenty five letters, and adding the three bearers, the two consonants set at the front and the five remaining sonorants and semivowels gives the thirty five of the painti. Nothing in that arrangement is arbitrary, and a learner who understands it is not memorising a sequence but reading a table. That is the practical advantage the Brahmic family has always had over alphabets whose order is inherited from an older writing system and means nothing.
