Etymology : English borrowed its word cerebrum directly from the Latin word for “brain,” but the adjective cerebral, though from the same source, took a slightly more circuitous route, making its way into English by way of French. Cerebrum has been used in our language as a name for the upper part of the brain since at least the 1570s. Cerebral has been appearing in print in English since the beginning of the 19th century, when it initially described the brain generally or the intellect. Other brainy descendants of cerebrum in English include cerebellum (the part of the brain between the brain stem and the back of the cerebrum) and cerebrate, a verb meaning “to use the mind” or “to think.”
