Taraji P. Henson stars in director Tyler Perry's new movie, "Acrimony," which opens in theaters this Friday, March 30.

What does "acrimony" mean? That was the question for many fans, who made the word one of Merriam-Webster's top lookups throughout March 2018, especially during primetime hours as ads for "Acrimony" aired.

Merriam-Webster helpfully shared the definition, and more background on the word:

"We define acrimony as 'anger and bitterness : harsh or biting sharpness especially of words, manner, or feelings.' Before the word had a meaning which enabled it to titularly function for a psychological thriller, acrimony was used in the sense 'bitterness or sharpness especially to the taste' (it came to English in the 16th century from Middle French, and can be traced before that back to the Latin word ācer, meaning 'sharp, biting, keen')."

In this case, "acrimony" describes the feelings of Taraji P. Henson's character: "A faithful wife tired of standing by her devious husband (Lyriq Bent) is enraged when it becomes clear she has been betrayed."

Tyler Perry told Page Six how he came up with this title for the movie:

"I was watching CNN and they described our president as 'acrimonious' — so I looked it up. I wanted it to describe who Melinda [the character played by Henson] was, and when I found the word I knew it had to be the title of my movie."

Here's the official trailer:The movie also stars Lyriq Bent, Crystle Stewart, Jazmyn Simon, Ptosha Storey, Ajiona Alexus, Antonio Madison, Bresha Webb, Danielle Nicolet, Nelson Estevez, and Kendrick Cross.
