the.com/dimness
the slow surrender of the visible, where shadows finally win the argument with light
means The state of being faintly lit or unclear, whether literally for light or figuratively for the mind's grasp of things.
from From Old English 'dimm,' meaning dark or obscure, with Germanic relatives across the north — Old Norse had 'dimmr' for the same gloom. The '-ness' is the trusty Old English suffix that turns a quality into a thing you can name, so 'dimness' is simply the noun-shaped form of being dim. The word's metaphorical reach — a dim memory, a dim wit — grew naturally from the literal one, since the unseen and the half-understood have always felt like cousins.
