In the Pandora myth, the Greek name for the hope left inside the jar is elpis.
Elpis is the Greek noun commonly translated as “hope,” though its range can also include expectation or anticipation. Hesiod places elpis inside the vessel after the other evils escape. Translators and commentators have long debated what this means, because hope can be read as a comfort preserved for humanity or as an expectation withheld from it.
The ambiguity comes from the poem's wording and from the broader meanings of ancient Greek terms. It is therefore safer to identify elpis as the named concept than to claim that the myth has one universally agreed moral.
The word is not the name of a goddess in the usual Olympian sense in this episode. It names the final condition or force remaining in Pandora's jar, alongside the evils that have gone out into the world.
