A guttural is not substituted for the palatal of vañc in the sense of 'going'.,
A वञ्च्यं वञ्चन्ति वणिजः, but वाङ्क्यं काष्ठं = कुटिलं ॥ Why is गतौ used, when we know from the Dhatupatha (Bhuadi 204) that वंच् means 'to go'? The specification shows that the roots possess many meanings other than those assigned to them in the Dhatupatha.,
