A. epiphany B. fancy C. phenomenon D. sycophant E. emphasis F. phase

The Greek word phainein shows through more clearly in some of our quiz words than others, but it underlies all of them. The groundwork for diaphanous was laid when phainein (meaning "to show") was combined with dia- (meaning "through"). From that pairing came the Greek diaphanēs, parent of the Medieval Latin diaphanus, which is the direct ancestor of our English word.
