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."
