'nerve' originates from Latin, specifically the word 'nervus,' where 'nervus' meant 'sinew, tendon, or nerve.'

'nervus' transformed into the Old French word 'nerf,' and eventually became the modern English word 'nerve' through Middle English.

Initially, it meant 'sinew or tendon,' but over time it evolved into its current meaning of 'a bundle of fibers in the body.'
