The story of the word

λοβός covered the lobe of the ear, the lobe of the liver and the pod of a bean, anything rounded that hangs. Medical Latin took it as lobus, and English had lobe by the early 1400s, meaning the ear. The lobes of the brain and the lungs were named later on the same principle, a division you can see the edge of. Lobotomy, coined in 1936, is a cut through one of them.
