Etymology

The word "tanker" emerged in the late 19th century, derived from "tank" (originally meaning "artificial reservoir," borrowed from Portuguese "tanque") + the agentive suffix "-er." The term initially described ships designed to transport liquid cargo (e.g., oil or water) in large tanks. Later, it expanded to include fuel-carrying aircraft and military vehicles. The suffix "-er" logically marks the word as a functional object (a vessel or vehicle "that carries tanks").
