vi. to expand and contract rhythmically; beat or throb

pulsate = puls<beat> + ate<verb suffix>
- puls (from Latin pulsus, meaning "beat, push, or strike")
- ate (a verb-forming suffix indicating action or process, from Latin -atus)
Etymology Origin:
Derived from Latin pulsare ("to beat, strike repeatedly"), the frequentative form of pellere ("to drive or push"). The root puls reflects rhythmic motion, later generalized to vibrations or throbbing. The suffix -ate standardizes it as a verb in English, preserving its dynamic essence.
