Ṭainka ਟ

Ṭainka is the sixteenth letter of the Gurmukhi painti and opens the retroflex series, the third of the five and the middle of the journey from the back of the mouth to the lips. Retroflex consonants are made with the tip of the tongue curled back to meet the roof of the mouth just behind the teeth ridge, and they are among the defining sounds of the languages of South Asia. No European alphabet has letters for them, which is why romanisation has to add a dot beneath a t or a d to write them at all, and why the atlas gives this letter and its neighbours diacritics in their display names.

Ṭainka writes an unaspirated voiceless retroflex t, which Punjabi distinguishes sharply from the dental t written six letters further on. The letter is also the one clear irregularity in the naming of the painti. Most Gurmukhi letter names are built by doubling the letter's own syllable, giving Kakka, Gagga, Jajja and the rest, but this letter is called Ṭainka, and the departure from the pattern is a small piece of evidence about the way the names settled. Retroflexion is also a piece of evidence in the long argument about how the languages of South Asia influenced one another, since it is shared across the Indo-Aryan and Dravidian families despite those families being unrelated, and is usually explained as a feature that spread by contact. A Gurmukhi reader has no need of that history, but it is the reason the letters exist: the Brahmic alphabets were built for languages that had these sounds, and every script in the family carries a retroflex row.

The names of the Gurmukhi letters are not words for objects. Hebrew and Greek inherited names that once meant ox, house and door, and the meanings travelled with the letters even after they had stopped being relevant; Gurmukhi did nothing of the kind. Its names are mnemonics built out of the letters themselves, so that saying the name teaches the sound, and a learner reciting the painti is drilling pronunciation rather than reciting a vocabulary. That is a real difference in what an alphabet can be, and it is worth stating plainly, because a reader who arrives from the Semitic and Greek tradition may expect a gloss for every letter and find none. Ṭainka is where the pattern is least tidy.

The doubling that produces Kakka from k and Jajja from j does not produce Ṭainka from the retroflex t, and while the tradition has carried the name unchanged, the atlas records the irregularity rather than smoothing it into a rule. What the names do preserve, consistently, is the order and the phonetic system, and that is what they were shaped to carry. The absence of object names also removes a source of confusion that the Semitic alphabets carry with them. A Hebrew or Greek learner is regularly told that a letter means ox or house, which is true of the name and not of the letter, and the gloss can be mistaken for a symbolic value the letter does not have. Gurmukhi offers no such handle. Its letters are sounds in an order, and any meaning they carry comes from the compositions written on them rather than from the names.
