chained_bear I like this word, but it always reminds me of cells--like "corpuscle" or "muscular"--or even "testicular."
If that ruins it for anyone, I'm sorryish. ;) Oct 23, 2007
npydyuan A fine feature of "crepuscular" is its ability to signify dusk OR dawn. The in-between times, the secret times.... Sep 16, 2007
samoritan In a strongly-worked essay on gun violence, Harlan Ellison once referred to Ronald Reagan as a "crepuscular old fart". May 17, 2007
polymorph One theory of the evolution of the human brain is that our distant crepuscular ancestors needed sharp vision to avoid predators. This lead to increased brain capacity necessary to process the higher image resolution that their enlarged optic nerve was delivering (I imagine a wide-eyed lemur-like creature constantly scanning its environment searching for danger in the twilight). Apr 8, 2007
beee I like this word. It is the inspiration for the last name of the heroine of "Dos Palabras," a short story by Isabel Allende. In Spanish it sounds quite romantic, but yes, I have to agree that the English pronunciation is less agreeable. Feb 15, 2007
valse I do agree this is a strange word...but it matches a pretty strange time of day. That beautiful, eerie glow and the darkness slowly creeping up. Of course, it can also be used to describe insects and other animals that come out around that time... Jan 4, 2007
tree odd, i just wrote this as a comment to someone on livejournal: the word crepuscular brings to mind rabbits, so for me it's a lovely, faintly sad word - sad because my bunnies have passed. it makes me think of twitching noses and shadows. Dec 27, 2006
billifer It reminds me of seafood. Crepuscular... crustacean.... Same thing. :) Dec 22, 2006
hanru Agreed. Twilight deserves a more pleasant-sounding word... Dec 9, 2006
emily_morine I'm not sure whether I love crepuscular or hate it. I love that there's a word for this concept, but the actual word itself seems more descriptive of an infected, peeling scab. Dec 8, 2006
