Why “vesperate” is a great word

VESPERATE — [Verb] To darken or grow dim as at the beginning of night. From the Latin vesper ("evening"), with the verb-forming suffix -ate; first attested in English in 1623. Unlike "darken," a general term for any loss of light, or "obscure," which implies a deliberate act of concealment, to vesperate is to evoke the gradual, atmospheric surrender specific to dusk. It is the slow leaching of color from a hillside, the subtle bleed of indigo that consumes the last amber edge of a roof, and the quiet instant a window transitions from portal to mirror—the world's oldest, gentlest disappearing act.
