Jhajja: The Gurmukhi Letter

Jhajja is the fourteenth letter of the Gurmukhi painti and occupies the voiced aspirate slot of the palatal series, the position Ghagga holds among the velars. Historically it wrote a j released with voice and breath together. In most modern Punjabi that sound no longer exists: the voiced aspirates of every series have lost both aspiration and voicing, and the syllable carries a tone instead. What makes the letter more than a fossil is that the tone is predictable from it. Punjabi tone is not written with any mark of its own, and a reader identifies it from these letters and from where they fall in the word, so a word spelled with Jhajja at its start is pronounced with a different pitch from one in which Jhajja stands later.

The spelling therefore continues to do useful work while no longer describing a consonant, which is an unusual position for a letter to be in and one of the more interesting facts about the Gurmukhi writing system. Its form is a stem carrying a doubled curve, distinguishable from Jajja by the second bend. The relationship between letter and tone is regular enough to be stated as a rule rather than learned word by word, which is the difference between a spelling that is merely historical and one that is still functional. A comparable case in English would be a silent letter that reliably told a reader which vowel to use; English has a few such patterns but none as systematic. In Punjabi the pattern covers a large part of the vocabulary, and it is one of the reasons the orthography has never come under serious pressure to change.
