Root Breakdown
Root-derivedFrom the puls- form of pellere (push). Your pulse is the heart pushing blood through the arteries in a steady beat — you feel each push as a throb. The same idea of a brief, repeated push gives the technical sense: a pulse of light or electricity. (The 'beans' meaning is unrelated — it comes from Latin puls, a thick porridge.)
