'enervate' originates from Latin, specifically the word 'enervare,' where 'e-' meant 'out of' and 'nervus' meant 'sinew or nerve.'

'enervare' transformed into the French word 'énervé,' and eventually became the modern English word 'enervate' through Middle English.

Initially, it meant 'to weaken physically,' but over time it evolved into its current meaning of 'to drain energy or vitality.'
