annihilate: [16] Annihilate comes from the past participle of the late Latin verb annihilāre, meaning literally ‘reduce to nothing’ (a formation based on the noun nihil ‘nothing’, source of English nihilism and nil). There was actually an earlier English verb, annihil, based on French annihiler, which appeared at the end of the 15th century, but it did not long survive the introduction of annihilate. => nihilism, nil[annihilate etymology, annihilate origin, 英语词源]
