Etymology: Smallpox was once called "variola" in Latin, a name that most English speakers never hear, and "varioloid" is built directly on it. The Latin term comes from "varius," meaning spotted or variegated, a reference to the pocked skin of the disease. Attaching the Greek-derived suffix "-oid," meaning "resembling" or "like," produced a word for a milder, smallpox-like illness. The pattern is a plain one: a Latin medical name plus a suffix that marks resemblance, the same way "android" means "man-like." A varioloid was a case of smallpox in a person who had some immunity, usually through vaccination or earlier exposure, so the illness was less severe and the pustules fewer. The word therefore names a modified form of a disease rather than a separate one, and it is a technical coinage rather than an ancient term.
