Did You Know?

Far from being removed from existence, obliterate is thriving in our language today with various senses that it has acquired over the years. True to its Latin source, oblitteratus—from the prefix ob-, meaning “in the way,” and littera, meaning “letter”—it began in the mid-16th century as a word for removing something from memory. Soon after, English speakers began to use it for the specific act of blotting out or obscuring anything written, and eventually its meaning was generalized to removing anything from existence. In the meantime, physicians began using obliterate for the surgical act of filling or closing up a vessel, cavity, or passage with tissue. Its final stamp on the English lexicon was delivered in the mid-19th century: “to cancel a postage or revenue stamp.”
