Other forms: darkened, darkening, darkens
To darken something is to make it darker: less light, deeper colour. You darken a room by closing the curtains, darken a photo with a slider, darken your tea by leaving the bag in.
Darken works both ways. You darken a wall with a second coat of paint, and the sky darkens on its own before a storm, with no object needed. It carries mood as well as light: a face darkens, a story darkens in the second half, a scandal darkens a whole career. The one fixed phrase is old and furious, and you will meet it in novels rather than in speech: never darken my door again. The opposite is lighten, in every one of these senses.

Darken is dark with -en stuck on the end, but the pair is ancient: Old English had deorcnian, from Proto-West Germanic dirkinon, and both already meant to darken. The same -en still builds verbs today in soften, harden and sharpen, so darken is a thousand-year-old example of a machine English never switched off.
