Ghagga: The Gurmukhi Letter

Ghagga is the ninth letter of the Gurmukhi painti and the fourth member of the velar series, the slot a Brahmic alphabet reserves for the voiced aspirate. Historically that is exactly what it wrote, a g released with breath and voice together, and that is still what it represents when Sanskritic vocabulary is read in a learned register. In ordinary modern Punjabi it does something different. The voiced aspirates of all five series have in most dialects lost both their aspiration and their voicing, and what has taken their place is pitch: the syllable is spoken with a low falling tone.

Punjabi is the only major Indo-Aryan language to have become tonal in this way, and the letters that once wrote voiced aspirates are the written record of a change the spelling never followed. Ghagga is therefore a letter whose orthography is older than its pronunciation, which is not a defect but a piece of evidence, since the distribution of tone in modern Punjabi can be predicted from where these letters stand in the older spelling. Its shape is a stem with a full loop, distinguishable from Gagga by the closure of that loop. The four voiced aspirates, one in each series except the retroflex, are the only letters in the painti whose modern value has to be stated twice, once for the reading tradition and once for the street. That is a manageable ambiguity in Punjabi because the two readings never compete for the same word; a reader knows which register is in play from the text in front of them.
