Ṛaṛa ੜ

Ṛaṛa is the thirty-fifth and last letter of the Gurmukhi painti, and reaching it completes the count that gives the alphabet its Punjabi name. It writes a retroflex flap: the tongue tip, curled back toward the roof of the mouth, strikes it once briefly and moves on. The sound is distinct from the r of Rara, which is made further forward and held longer, and from the retroflex stop of Ḍadda, which is a full closure rather than a strike, and Punjabi keeps all three apart. Its most unusual property is where it can appear.

Ṛaṛa never begins a word. It occurs medially and finally and nowhere else, which makes it the only letter of the painti whose distribution is constrained by a rule of the language rather than by the accidents of vocabulary, and a learner is taught that rule alongside the shape. It is also encoded in its own right rather than as a marked variant of another letter, which reflects its standing in Punjabi as a full consonant rather than as an extension of the kind the six dotted letters represent. In the recitation of the alphabet it is the letter on which the painti stops. The three way distinction between Rara, Ḍadda and Ṛaṛa is one that a learner from outside the region typically hears as a single sound at first, and it is the last of the retroflex contrasts the painti asks for. Because Ṛaṛa cannot begin a word, a reader also has a positional cue that the other two do not offer: a retroflex sound at the start of a word is never this letter, which narrows the choice before the ear has to do any work at all.

The number thirty-five is not incidental to Gurmukhi; it is the name of the alphabet. Painti is the Punjabi word for thirty-five, and to speak of the painti is to speak of the letters as a fixed and complete set rather than as a list that might grow. That has shaped how the script has handled everything added since. The six dotted letters for Perso-Arabic and English sounds were not folded into the alphabet and renumbered; they were kept outside it, taught separately, and described as extensions, so that the painti remains thirty-five and the additions remain visibly additional. The same is true of the vowel signs, the nasal marks and the digits, none of which is counted among the letters. A script that named itself by its count committed itself to a boundary, and the boundary has held for as long as the name has.

Ṛaṛa is the letter that marks it. Nothing about the sound it writes gives it that role, and it holds the last place for reasons of inherited ordering rather than of importance, but the effect is that the closing of the alphabet is a definite event: a learner reciting the painti knows exactly where it ends, and so does everyone listening.

A further consequence follows for cataloguing. The painti is thirty-five letters and the extensions are not part of it, so a count of Gurmukhi characters depends on what is being asked. A reference work that lists thirty-five is describing the alphabet as the tradition names it; one that lists forty-one is including the dotted letters; one that counts encoded characters is including the vowel signs, the nasal marks, the digits and several signs used only in the scripture. None is wrong and they are not interchangeable. This atlas holds the thirty-five and records the extensions on the letters they are built from.
