Eradicate (verb): to eradicate something is to get rid of it, to destroy it, and to kiss it goodbye.

I encountered the word by looking at “Era.” I know what Era means but It has nothing to do with this word. Also as I kept on reading my article, the next sentence helped me learn the word better. Another encounter, since Eradicate definition is to get rid of something, Era does sound like Erase.

Example: Although we may never completely eradicate every disease on earth, it’s heartening to see the progress medicine has made on so many fronts.
