'excitation' originates from Latin, specifically the word 'excitatio,' where 'excitare' meant 'to call forth or awaken.'

'excitatio' transformed into the Old French word 'excitation,' and eventually became the modern English word 'excitation' through Middle English.

Initially, it meant 'to awaken or stir up,' but over time it evolved into its current meanings related to arousal and energization.
