Crepuscular. The word fairly trips off the tongue, making even the most uneducated person sound sophisticated — assuming it is used correctly, that is.

The word refers to an animal that is primarily active at twilight, such as deer. They are creatures that have mastered the “in-between” realm that is neither bright nor dark. Other crepuscular animals include coyotes, porcupines, and many songbirds.

Word of the Day Challenge encourages the use of crepuscular in a poem, story, or other writing exercise. Commonplace Fun Facts rises to this challenge with the following literary submission:

Eschewing darkness and light,

Deer are crepuscular.

It makes up for the fact

They are not very muscular.

Take that, Dr. Seuss.
