'pulsate' originates from Latin, specifically the word 'pulsare,' where 'puls-' meant 'to beat or strike.'

'pulsare' transformed into the Late Latin word 'pulsatus,' and eventually became the modern English word 'pulsate.'

Initially, it meant 'to beat or strike,' but over time it evolved into its current meaning of 'to throb or vibrate rhythmically.'
