Late 14th century, "state or fact of forgetting," from Old French oblivion (13th century) and directly from Latin oblīviōnem (“forgetfulness; a being forgotten”), from oblīvīscī (“forget”), originally "even out, smooth over, efface," from ob- (“over”) + root of lēvis (“smooth”), from Proto-Indo-European *lei-w-, from root *(s)lei- (“slime, slimy, sticky”) (see slime (noun)). Meaning "state of being forgotten" is early 15th century.
