What is the etymology of episodes?
First English attest in 1678, from Greek epeisodion"addition," originally neutral form of epeisodios "coming in besides," from epi- "in addition" + eisodos "a coming in, entrance" (from eis "into" + hodos "way"). Originally commentary between two choric songs in Greek tragedy; extended by 1679 to "any incidental narrative or digression in a story, poem, etc." Sense of "outstanding incident, experience" first recorded in English 1773.
