episodic

Etymology

It is formed from English episode + -ic.^[2][3][4][5] The base is from French épisode or directly from Ancient Greek ἐπεισόδιον (epeisódion, “an addition”), the neuter of ἐπεισόδιος (epeisódios, “coming in besides”), from ἐπί (epí, “in addition”) and εἴσοδος (eísodos, “entrance”), which is from εἰς (eis, “into”) and ὁδός (hodós, “way”).^[2][3][6] The longer episodical is older, from the 1660s.^[3]

Earliest recorded meaning

Of the nature of an episode; incidental: 1711, in Lord Shaftesbury's Characteristicks, "The same Episodick Liberty".^[2][7]

Semantic evolution

An episode was first something incidental, coming in from the side of the main action,^[6] and the adjective first meant incidental or occasional.^[2] From 1867 it was used of a literary work that brings in many episodes, often loosely connected.^[2][7] From there it came to describe anything made up of separate episodes.^[7][8] The sense "occurring at irregular intervals, sporadic" is recorded by the Shorter Oxford from the early 18th century,^[4] and is now common of illnesses.^[9] Psychology took up episodic memory, the memory of particular events in one's life, from 1922.^[2]
