Etymology
Origin of acrimonious
From the Medieval Latin word ācrimōniōsus, dating back to 1605–15. See acrimony, -ous
Explanation
Locked in a mean-spirited, bitter argument? That's an acrimonious situation that might result in fists flying unless you and your opponent can cool down. If you're familiar with the adjective acrid, which means "having a strongly unpleasant taste or smell," you might guess that acrimonious probably refers to something unpleasant, too. And you'd be right. Until the mid-nineteenth century, acrimonious meant the same thing as acrid. But while acrid is still most commonly used in a literal sense (as in "an acrid odor"), acrimonious is now used to describe things like angry and bitter speeches or debates. Both words come to English from the Latin word acer, meaning "sharp." Keep sharp objects locked up if a showdown gets too acrimonious.
