Thattha ਥ

Thattha is the twenty-second letter of the Gurmukhi painti and the second member of the dental series, the aspirated partner of Tatta. It writes a dental t released with a puff of breath. It is emphatically not the th of English thin or this, which are fricatives made by holding the tongue against the teeth rather than by releasing a closure, and which Punjabi does not have at all. This is the letter whose standard romanisation misleads most reliably, since a reader who applies English values to the two letters t and h together will produce a sound that appears nowhere in the language. The confusion is worth naming because it runs in both directions: Punjabi speakers learning English commonly substitute an aspirated dental stop for the English fricative, which is the same mismatch seen from the other side.

Within Punjabi the aspiration is contrastive and the letter is fully alive, having kept its breath where the voiced aspirates lost theirs. In transliteration it needs no dot, and that is exactly the problem the atlas has to solve in its display names: without a dot beneath the retroflex aspirate five letters earlier, the two letters would carry the same romanised name and a reader would have no way to tell which was meant. The dot is therefore not ornament but the whole of the distinction.

Gurmukhi spent most of its history as a script with an authoritative text and no authoritative spelling for anything else. The Guru Granth Sahib fixed the orthography of its own language completely, and that orthography was never revised because the volume is treated as a living Guru whose wording is not open to editorial change.

Everything outside the scripture was another matter. Punjabi written for correspondence, accounts, poetry and pamphlets followed the scriptural model loosely and local practice otherwise, and the same word could be spelled several ways without anyone considering it an error. Standardisation of modern Punjabi orthography came much later, through schooling, publishing and the work of Punjabi language institutions, and it had to settle questions the scripture did not answer because the vocabulary had not yet existed. The dotted extensions are the visible part of that process. Thattha sits on the quiet side of it: the dental aspirate needed no new sign, appears in the scripture and in the newspaper alike, and is spelled the same way in both. Letters like this one are the reason standardisation was possible at all, since the great majority of the alphabet needed no decision and the argument could be confined to a small number of genuinely open cases.
