Since I can’t imagine any reason I need to stress the importance of an understanding of and an ability to use these words, now more than ever, I’ll post this context clues worksheet on the noun epidemic and this one on the noun pandemic without editorial comment.
However, a note on usage on epidemic and pandemic seems de rigueur. Differentiating the use of these two nouns is as easy as understanding their Greek roots: epi means on, upon, outside, over, among, at, after, to, and can best be understood, as some of those prepositions connote, as local; pan (along with panto) simply means all, and can best be understood, in our current circumstances, as meaning everywhere, as all connotes.
