"“Rajput is a corrupt form of the Vedic word Rajputra. It occurs in Rigveda, Yajurvedic Kaphak Samhita, and Aitareya Bramana of the Rigveda as a synonym for Râjanya. ...In Mahabharata also the word Rajputra has been used in the sense of nobles and chiefs, as well as ordinary Kshatriyas. The literal meaning of Kshatriya again is the son of a Kshatra. ... So the primary meaning of Rajanya and Kshatriya is the same and Rajputra is used for either of the two words though its meaning becomes distinct as we proceed on the long road of time... As pointed out by G.H. Ojha in Rajputane ka Itihasa Vol. I, Rajputras have been referred to in Kautilya’s Arthasastra, Kalidasa’s Malvikagnimitra, Asvaghosha’s Saundarananda and Banabhatta’s Harshacharita and Kadambari. The word has been used with different connotations by these authors. In Kautilya’s work it implies sons of the king while by Kalidasa and Asvaghosha it is used for nobles. Banabhatta in the first work uses it in the sense of nobles and in the latter work as sons of the nobles”"
