What does acrimoniousness mean?
Acrimoniousness is a formal noun denoting the quality of being acrimonious — that is, marked by bitterness, rancor, and sharpness of temper or language, particularly in disputes and prolonged conflicts. Where "acrimony" names the bitter feeling itself, "acrimoniousness" emphasizes the character or condition of something suffused with that feeling, such as a quarrel, lawsuit, or political campaign. The word belongs to an elevated register and appears relatively rarely compared with its shorter sibling; writers typically choose it when they want to stress the pervasive, defining harshness of an interaction rather than a momentary outburst. It derives from Latin roots meaning pungent or sharp, a metaphor extended from taste to temperament. Its antonyms include cordiality, goodwill, and amity.

It's the heavyweight cousin of "acrimony" — so rarely used that even seasoned editors reach for it only when ordinary bitterness just won't do.

Etymology of acrimoniousness
Acrimoniousness is formed from the adjective "acrimonious," which traces back through Late Latin "acrimoniosus" to Latin "acrimonia," meaning sharpness or pungency, itself derived from "acer" (sharp, keen). The underlying root is the same one that gives English "acrid" and "acerbity." The word entered English in the early modern period alongside "acrimony" and "acrimonious," with the suffix "-ness" added to form an abstract noun denoting the quality described by the adjective.
