Chhachha: The Gurmukhi Letter

Chhachha is the twelfth letter of the Gurmukhi painti and the second member of the palatal series, standing to Chachcha as Khakkha stands to Kakka. The two are made at the same point in the mouth, with the tongue against the hard palate, and they differ only in the breath released as the closure opens. That difference is contrastive in Punjabi, which is to say that it distinguishes words, so a speaker of a language without aspirated consonants has to learn to produce it deliberately rather than treating it as emphasis. Chhachha belongs to the voiceless half of the aspirate set and has kept its breath in modern speech, unlike the voiced aspirate two places further along the same series.

The letter also carries an extra load in the modern language: where a borrowed word contains a consonant Punjabi does not hold, and the nearest native sound is an aspirated palatal, Chhachha is what the borrowing is written with, so its distribution in modern Punjabi is wider than its distribution in the older language of the scripture. The aspirated palatal is also a useful case for thinking about what a letter records. Chhachha is one sign, but the sound it writes is an affricate with a breath after it, which a phonetician would describe with three separate features. Brahmic alphabets are indifferent to that analysis: they treat the syllable-initial consonant as a unit and give it one sign, which is part of why they can cover a large phonology with a small inventory. A learner therefore acquires sounds rather than features, and the grid does the analytical work.
