Flambeau comes from the Old French word *flambeau*, meaning torch or flame. The word is derived from *flambe* (meaning flame) and the suffix *-eau*, which is a diminutive or augmentative suffix in French. Thus, flambeau refers to a source of light, specifically a torch that produces flame.
Imagine a small 'flame' ('flambe') that lights up the darkness, and remember that a 'flambeau' is a torch that provides light.
