Etymology: "Acrotism" is a medical term for the absence of a pulse, built in New Latin from Ancient Greek parts that describe the sound and motion of a beating heart. The first element, "a-", is the Greek privative prefix meaning "without," the same prefix found in words like "atheist" or "anaerobic." The second, "krotos," meant "a rattling" or "a beating," the sort of percussive knock that a pulse was once imagined to make, and the ending "-ismus" turns the combination into a condition or state. The word therefore describes a pulse-less condition through a negation of its Greek name: nothing is beating, so the term is literally "no-beating." Because the coinage draws on classical roots, it reflects the physicians of early modern and later European medicine who needed precise vocabulary for the clinical signs they observed, rather than any ancient Greek medical usage of this exact form.
