From Star Wars, the word *lightsaber.*

For those who might not know, a lightsaber is pretty much a glowing blade of laser light that slices through anything. I know that *luma* or *hela* might be a part of it. And, would *saber* be *hakglavo* or *sabro*? Dankon.

EDIT: In French, it's *un sabre laser*, if that helps any.
