How Should You Use implacable?

Implacable is based on the Latin verb placare, meaning "to calm" or "to soothe." It joins 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 the 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."
