Etymology: The noun "pulse" comes from Latin "pulsus," meaning "beat" or "stroke," from "pellere," "to drive or push." The beat of the blood through the arteries was the original sense, and the word reached English in Late Middle English through Anglo-Norman and Old French "pous" and "pouls," the same word that still means the pulse in modern French. Latin "pulsare," the frequentative of "pellere," meant to strike repeatedly, to batter or hammer. That verb gave English "pulsen," meaning to throb, and the verb "pulse" that the form "pulsing" comes from. It is a doublet of "push," which descends from the same Latin root by a different route. Pulse also has a separate, unrelated history. It was once a name for porridge made from ground grain, from Latin "puls," and it later came to mean the edible seeds of leguminous plants, such as lentils and broad beans. The two senses of the word arrived in English as homonyms, so the beat and the bean share no meaning.
