70 PALA TALISATION. If the conjunct is made up of the तवर्ग and य or to a limited extent व, चवर्ग takes the place of the तवर्ग.
____A. Groups with य : त्य=च्च : सत्य =सच्च true ; नित्य = निच्च always ; प्रत्यय = पञ्चय confidence ; कृत्य = किच्च duty; अत्यंत = अच्चंत very much; आधिपत्य = आहेवच्च lordship; प्रेत्य = पेच्च in the next life; वैयापृत्य = वेयावच्च help; त्यजति = चयइ abandons; थ्य = च्छ : पथ्य पच्छ wholesome; मिथ्या = मिच्छा false; तथ्य = तच्छ true; रथ्या रच्छा street; नेपथ्य = नेवच्छ dress; द्य= ज : अद्य = अज to-day; मद्य =मज wine; अवद्य = अवज्ज sin; वैद्य = वेज physician ; खाद्य = खज eatables ; विद्या - विजा science ; ध्य = ज्झः वध्य = वज्झ to be killed ; उपाध्याय = उवज्झाय teacher; स्वाध्याय = सज्झाय study; अध्यवसाय = अज्झवसाय resolution ; ध्यात = झाय meditated ; मध्य = मज्झ middle.

The resulting sound is an affricative as are Sanskrit
