Thursday (because I lost track of time) Word: Crepuscular & Crepuscule

crepuscular |krəˈpəskyələr|adjectiveof, resembling, or relating to twilight.• Zoology (of an animal) appearing or active in twilight.ORIGIN mid 17th cent.: from Latin crepusculum‘twilight’ + -ar 1 .

crepuscule |kriˈpəsˌkyoōl|nounthe period of partial darkness at the beginning or end of the day; twilight.

I acquired this word watching a nature documentary about deer on PBS. Apparently, deer are crepuscular. I also learned that the "deer in the headlight" phenomena has nothing to do with fear. Instead, their brains get so overloaded with information, they simply can't decide what to do.
