- eradicate:  Semantically, eradicate is an analogous formation to uproot. It comes from the past participle of Latin ērādicāre ‘pull out by the roots’, a compound verb formed from the prefix ex- ‘out’ and rādix ‘root’ (source of English radical and radish and related to English root). In the 16th and 17th centuries it was often used literally (‘oaks eradicated by a prodigious whirlwind’, Thomas Nabbes, Hannibal and Scipio 1637), but since then the metaphorical ‘remove totally’ has taken over.
