Did You Know?

Oblivion was derived via Middle English and Anglo-French from Latin oblivisci, which means "to forget." This form may have stemmed from combining ob- ("in the way") and levis ("smooth"). In the past, oblivion has been used in reference to the River Lethe, which according to Greek myth flowed through the Underworld and induced a state of forgetfulness in anyone who drank its water. Among those who have used the word this way is the poet John Milton, who wrote in Paradise Lost, "Farr off from these a slow and silent stream, Lethe the River of Oblivion roules Her watrie Labyrinth."

Origin of oblivion

Middle English, from Anglo-French, from Latin oblivion-, oblivio, from oblivisci to forget, perhaps from ob- in the way + levis smooth — more at ob-, levigate

First Known Use: 14th century
