bomb-sniffing

The compound "bomb-sniffing" is a modern, transparent formation in English. The first element, "bomb," originates from a Latin word for a deep, hollow sound, which evolved to denote explosive devices that produce such noises. The second element, "sniff," is an onomatopoeic word imitating the sound of drawing air in through the nose to smell. The suffix "-ing" is a productive adjectival ending from Old English. The literal logic of the combined morphemes—"the action of smelling for bombs"—directly and vividly describes the specialized capability of animals trained to locate hidden explosives through their acute sense of smell.
