Origin & History of “episode”

In modern English, an episode is a component in a series of connected events, but originally it was something incidental, coming in adventitiously from the side. The word comes from Greek epeisódion ‘addition’, a noun use of the adjective epeisódios ‘coming in besides’. this was a compound formed from the prefix epí- ‘besides’ and the noun eísodos ‘coming in, entrance’ – which in turn was a compound formed from the preposition eis ‘into’ and hodós ‘way’ (a relative of Russian chodit’ ‘go’).
