The word "spark" refers to a small, fiery particle that is emitted from a fire or a source of heat. More broadly, it can also mean a tiny flash of light or a bright idea that initiates something larger. In various contexts, "spark" can be used to describe the start of a fire, a sudden idea, or the initial energy that triggers a reaction or event.
The word "spark" comes from Middle English "sperke," which in turn comes from Old English "spearca," meaning a small particle or fiery particle. The roots can be traced back to Proto-Germanic "*sparkÅ," which is related to similar words in other Germanic languages that also denote light or fire.
