The affixes ālac and āṭac come in the sense of matup after vāc , the word denoting 'a talkative'.,
This debars ग्मिन् ॥ Thus वाचालः 'garrulous', वाचाटः ॥
Vart:- These affixes come when contempt is expressed. An orator (वाग्मी) also talks much, but to the purpose. He will not be called वाचालः or वाचाटः ॥,
