The Root of Eradicate Is, Literally, Root

Given that eradicate first meant "to pull up by the roots," it's not surprising that the root of eradicate means, in fact, "root." Eradicate, which first turned up in English in the 16th century, comes from eradicatus, the past participle of the Latin verb eradicare. Eradicare, in turn, can be traced back to the Latin word radix, meaning "root" or "radish." Although eradicate began life as a word for literal uprooting, by the mid-17th century it had developed a metaphorical application to removing things the way one might yank an undesirable weed up by the roots. Other descendants of radix in English include radical and radish. Even the word root itself is related; it comes from the same ancient word that gave Latin radix.
