Manava Dharmashastra 2.31

2.31

maṅgalyaṃ brāhmaṇasya syāt kṣatriyasya balānvitam
vaiśyasya dhanasaṃyuktaṃ śūdrasya tu jugupsitam //

Let (the first part of) a Brahmana's name (denote something) auspicious, a Kshatriya's be connected with power, and a Vaisya's with wealth, but a Sudra's (express something) contemptible.
