Why “lightkeeper” is a great word
LIGHTKEEPER — [Noun] A person responsible for maintaining and operating the light in a lighthouse or lightship. From light (noun, meaning "a source of illumination") + keeper (noun, meaning "one who has charge of something"). Unlike "lighthouse keeper," which grounds the duty in the stone tower, or "beacon keeper," which could tend any signal fire, a lightkeeper is defined by the elemental flame itself. It is the nightly polishing of the vast, cold Fresnel lens; the rhythmic winding of the weight-driven clockwork; the patient trimming of the wick in the whale-oil lamp—a solitary covenant against the consuming dark, the stewardship of a fixed star in a mutable world.
