'Wisdom Is Heavy Stuff'

From a biochemist I learned a phrase new to me – “epigenetic switching.” It means changes in gene expression without corresponding changes in the DNA sequence. What struck me was the profusion of English words with the prefix epi-: epitaph, epilogue, epitome, epicenter, epithet, episode, epinephrine, epilepsy, epidermis, epithalamium, epiglottis, epicarp, epidemic, Silas Marner’s adopted daughter and my favorite, epigram. English is epically promiscuous. The root is the Greek epi meaning “upon, at, close upon (in space or time), on the occasion of, in addition.” “Epigram” is from ἐπίγραμμα (epigramma), “inscription,” from a related verb meaning “to write on, inscribe.” For the Greeks, epigrams started as brief verses written on votive offerings or monuments to the dead. Their appeal, for this reader, is terseness and wit. They mean something and are about something, rare qualities in poetry today. Every syllable has its place. None is superfluous. Take “You Don’t Have to Be So Smart”…
