Etymology: "Infecter" is simply "infect" with the agent suffix "-er" attached, meaning one that performs the action of infecting. The base verb "infect" comes from Latin "inficere," literally "to dip into" or "to stain," built from "in-" meaning "into" and "facere" meaning "to make" or "to do." The idea of dipping something into a substance gave rise to the sense of contaminating it, and from there to passing disease to a body. The suffix "-er" is one of English's most productive ways of naming a person, thing, or agent that does something. Attached to a verb such as "infect," it produces a noun for whatever carries out the action. Because "infect" already names the spreading of disease, "infecter" needed no new coinage of its meaning; it simply labels the agent that transmits the contamination, whether a carrier, a vector, or a substance.
