Definition: continuous forward movement
I found this word in “The Story of An Hour” by Kate Chopin. It is located on the second page second paragraph in the third sentence. “But she saw beyond that bitter moment a long procession of years to come that would come that would belong to her absolutely.”
It makes more sense now that I know the definition and the way that the author means that Mrs.Mallard would be thinking about the way that she can move forward now that she only had herself to worry about.
