Plectrum

plectrum \ˈplek-trəm\ noun: a small thin piece (as of plastic or metal) used to pluck the strings of a stringed instrument; pick

Etymology: Latin, from Greek plēktron, from plēssein to strike

Last night I heard a busker strumming Libba Cotten's "Freight Train." Strumming! As in, "not fingerpicking." What's the world coming to?
