词源

PIE word *h₁epi (start of 17th century) From earlier obliterat, learned borrowing from Latin obliterātus, oblitterātus (“having been blotted out, effaced, erased; having been forgotten”) (see -ate (verb-forming suffix, of participial origin)). Obliterātus and oblitterātus are respectively the perfect passive participles of obliterō and oblitterō (“to blot out, efface, erase, obliterate; to cause to be forgotten”), probably either: * from ob- (prefix meaning ‘against; towards’) + littera (“letter of the alphabet; (metonymically) handwriting”) (further etymology unknown); or * from oblītus (“disregarded, neglected; forgotten”), influenced by littera. Oblītus is the perfect passive participle of oblinō (“to daub over, besmear”), from ob- + possibly ultimately from Proto-Indo-European *h₁lengʷʰ- (“not heavy, light; brief; swift”). Cognates * Catalan obliterar (“to erase; to cancel (a stamp); to close up or fill (a body cavity, vessel, etc.)”) * Middle French oblitérer (modern French oblitérer (“to cause (memories) to fade; to block, obstruct; to cancel (a stamp, ticket, etc.) so it cannot be reused”)) * Portuguese obliterar (“to destroy completely; to erase”) * Spanish obliterar (“to destroy completely; to erase”)
