‘Spark words’ and the hidden history of ‘panic’ and ‘Ritalin,’ with Martha Barnette

1104. This week with Martha Barnette, co-host of "A Way with Words" and author of "Friends with Words: Adventures in Languageland," we look at the concept of a "spark word" — the word that ignites a love of language. We also look at fascinating etymologies from ancient Greek, including the surprising connections between "Nike" and "fennel," and the origins of "panic" and "Ritalin."
