Beyond the definition
Crepuscular is the adjective that gloaming never quite became. It describes not just the light but the quality of things seen in that light — the way they lose definition, soften, become briefly ambiguous. Crepuscular is the word for things that only fully reveal themselves in the in-between: certain moods, certain kinds of beauty, certain conversations.
Origin & history
From Latin crepusculum (twilight). English usage from the 1660s. Originally used in natural history to describe animals active at dawn and dusk. Extended to describe anything with the quality of twilight.
