Oblivion asks forgetfulness of us in both its meaning and etymology. The word’s Latin source, oblīvīscī, means “to forget; to put out of mind,” and since its 14th century adoption into English, oblivion has hewed close to meanings having to do with forgetting. The word has also long had an association with the [River Lethe](https://www.merriam-webster.com/dictionary/lethe), which according to Greek myth flowed through the Underworld and caused anyone who drank its water to forget their past; 17th century poet John Milton wrote about “Lethe the River of Oblivion” in [Paradise Lost](https://www.britannica.com/topic/Paradise-Lost-epic-poem-by-Milton). The adjective [oblivious](https://www.merriam-webster.com/dictionary/oblivious) (“lacking remembrance, memory, or mindful attention”) followed oblivion a century later, but not into oblivion—both words have proved [obdurate](https://www.merriam-webster.com/dictionary/obdurate) against the [erosive](https://www.merriam-webster.com/dictionary/erosive) currents of time.
