कौन्तेयराधेयन्यायः

It has its origin in the fact that Karna, a hero of the Mahabharat, was in reality the son of Kunti, but as he was brought up from his infancy by a carpenter-woman named Radha, he was ordinarily called Radheya. This maxim is applied to the cases in which a fictitious appellation gets currency in suppression of the real one.
