rude: [14] Rude comes via Old French rude from Latin rudis ‘rough, raw’. This seems originally to have denoted ‘rough unpolished stone’ – it was related to Latin rūdus ‘broken stone’ – but its ultimate origins are unknown. From it were derived rudīmentum ‘beginning’ (etymologically ‘raw state’), which has given English rudiment [16], and ērudīre ‘take the roughness out of’, hence ‘polish, teach’, source of English erudite. => erudite, rot, rudiment
rude (adj.)
late 13c., "coarse, rough" (of surfaces), from Old French ruide (13c.) or directly from Latin rudis "rough, crude, unlearned," perhaps related to rudus "rubble." Sense of "ill-mannered, uncultured; uneducated, uncultured" is from mid-14c. Rude boy (also rudie, for short) in Jamaican slang is attested from 1967. Figurative phrase rude awakening is attested from 1895.
