firebomb

The compound word 'firebomb' is a modern English formation that transparently combines two distinct and ancient roots. The first element, 'fire', originates from the Proto-Germanic 'fōr', a term with deep Indo-European roots related to the concept of burning and light. The second element, 'bomb', has a more circuitous history, entering English via French and Italian from the Latin 'bombus', itself borrowed from the Greek 'bombos', which imitated a deep, resonant sound. The literal logic of the compound is perfectly clear: a bomb intended to cause a fire. This meaning evolved from the mid-20th century to specifically describe an incendiary device, often used in warfare or arson, where the primary destructive mechanism is the resulting conflagration rather than solely the blast.
