The word "pulsate" originates from the Latin verb "pulsare", which means "to beat, strike, or throb". It is derived from the Latin noun "pulsus", meaning "a beating or pulse". From Latin, the word evolved in Old French as "pulsacion" before entering Middle English as "pulsacion" or "pulsey". Over time, it transformed into its modern form "pulsate", which describes a rhythmic or regular beating or throbbing.
