adjective / verb

dim

DIM/dɪm/

Giving little light or brightness.

The bedside lamp casts dim light over the closed book.

Etymology

Old English dimm already described things that were dark or indistinct. The modern meaning preserves that connection between weak light and difficulty seeing something clearly.
