#131 A Writing Over and Upon Epi-

Published: Sept. 1, 2016, 7 a.m.

Prefixes are key morphemes in English vocabulary that begin words. The English prefix epi-, which means “over” or “upon,” appears in a good number of English vocabulary words, such as epidermis and epitaph. You can remember that the prefix epi- means “upon” from the noun epidemic, which is a widespread disease that comes “upon” people; you can also recall that epi- means “over” via the word epidermis, which is the outer skin that lies “over” lower layers of skin.
