Pronunciation

  • UK: /ˈnjʊəɹəl/[1]
  • US: /ˈnʊɹəl/, /ˈnɝəl/[1]

Etymology

It was formed in English from Ancient Greek νεῦρον (neûron, “nerve, sinew”) and the adjective suffix -al,[2][3][4][5][6] after other formations in neuro-;[2] Barnhart and Merriam-Webster analyse it as “neur-” + “-al”.[7][8] The OED compares neural, recorded in 1855.[2] The Greek word is related to nervus, the source of nerve.[9]

Earliest recorded meaning

In zoology and anatomy, on the side of the body where the spinal cord lies, especially in neural arch and neural spine: 1846.[2] Etymonline dates the word to 1830,[3] Barnhart to 1839–47,[7] Merriam-Webster to about 1847,[8] and Dictionary.com to 1830–40.[10]

Semantic evolution

The physiological sense, relating to the activity of nerves or the nervous system, is recorded in Herbert Spencer in 1864,[2] the biological sense, of the nature of nerves or nerve tissue, from 1882,[2] and the medical sense, affecting the nervous system, from 1883.[2] A science-fiction use, connected directly to the nervous system, as of an interface between a device and the brain, appears in 1976.[2] Collins also records the computing sense, relating to a network of components that imitates the working of the brain, as in a neural network.[11]
