Neoseure is a noun derived from the verb neoseolgeorida, which meant to ramble on at length or chatter away. Over time the root "neoseol-" shifted into neoseure and became a noun in its own right. But neoseure carries a nuance quite different from ordinary chatter. It is not tedious nagging; it is the knack for spinning out a story in a droll, disarming way that keeps listeners laughing and entertained. The patter of a Joseon-era marketplace medicine seller or a traveling storyteller, gathering a crowd and reeling off an amusing tale, was exactly this neoseure. The idiom neoseure-reul tteolda means to put on this sort of cheerful, breezy performance of talk.
