The word "tinder" traces back to Old English tynder, derived from the verb tendan ("to kindle"). The root tind- reflects the action of igniting, while -er denotes a noun referring to the material itself. Historically, tinder was essential for fire-starting, often made from charred cloth or dry plant matter. Over time, it evolved metaphorically to describe anything that fuels agitation or conflict.
