Etymology

It is borrowed from Latin crūdus (“raw, rough, bloody”),[2][3][4] from a suffixed form of an Indo-European root meaning raw flesh, also the source of raw.[3][4][5] cruel comes from the same Latin root.[6]

Earliest recorded meaning

In the natural or raw state, not changed by any process: about 1386 in the OED, about 1395 in Barnhart, in Chaucer.[7][2]

Semantic evolution

Of food in the stomach, undigested (1533), and of fruit, unripe (1555), are early senses now gone or archaic.[7][4] Rough, lacking finish or skill, belongs to the 17th century,[4] and lacking grace or refinement is first recorded in 1650, the 1640s in Etymonline.[2][3] Crude oil, natural mineral oil, is from 1865,[7][3] and the noun crude for it from about 1904.[5] Crudity is probably from before 1325.[2]
