The word "wildfire" combines "wild" (Old English wilde, meaning "untamed" or "natural") and "fire" (Old English fȳr). Historically, it referred to fires caused by lightning or human neglect in forests or grasslands. Over time, it gained metaphorical use to describe phenomena that spread uncontrollably, mirroring the rapid, unpredictable nature of literal wildfires. The morphemes preserve their original meanings while forming a cohesive modern term.
