epic (adj.) Look up epic at Dictionary.com
1580s, perhaps via Middle French épique or directly from Latin epicus, from Greek epikos, from epos "word, story, poem," from PIE *wekw- "to speak" (see voice). Extended sense of "grand, heroic" first recorded in English 1731. From 1706 as a noun in reference to an epic poem, "A long narrative told on a grand scale of time and place, featuring a larger-than-life protagonist and heroic actions" [Miller Williams, "Patterns of Poetry].
