Did you know?
"Implacable" comes from the Latin word "implacabilis," with which it shares the meaning "not easily placated." Ultimately, it comes from the verb "placare," meaning "to calm" or "to soothe." "Implacable" adds the negative "im-" to the root to describe something that cannot be calmed or soothed or altered. The root "placare" also gave us "placate." You may ask, what about similar-looking words "placid" and "placebo"? These words are related to "implacable" and "placate," but not as closely as you might suspect. They come from the Latin verb "placēre," a relative of "placare" that means "to please."
