Etymology: The etymology of the word acrimony is unclear. Some people believe it comes from the Latin, ‘acro’ meaning high and Moneo meaning to speak out loud, so acrimony would mean – high speaking out loudly. Others believe it comes from the Greek words’ kharis,’ meaning sharpness or keenness, and’ Monos,’ meaning single. Acrimony would be – single sharpness or bitterness.

In modern terms, acrimony means a state of being angry and hostile or a feeling of aversion.

It is from the Latin words acrimonia, meaning “sharpness, keenness,” and acrimen, meaning “sharp pain.” In the early 15th century, the word acrimony came into English vocabulary. In Middle English, it had a more literal meaning of “the sharp edge of a weapon.”
