Carburetor → It is formed from "carburare" (from Latin, meaning to mix with carbon) and the suffix "-tor" (meaning one who or that which). The word "carburetor" refers to a device that mixes air with a fine spray of liquid fuel, particularly carbon-based fuel, for combustion in an engine.
Think of a device that 'mixes' ('carburare') carbon with air — that's what a carburetor does.
