The quality or state of being sharp, harsh, or biting in taste, smell, or manner; acrimony or severity.
From Latin 'acer' (sharp) + '-itude' (suffix forming abstract nouns), related to 'acrid' and 'acrimony', describing the pungent quality of sharp sensations or sharp behavior.
This word is basically the Latin cousin of 'acrimony,' but it emphasizes the physical sensation of sharpness—like how chili peppers and harsh words both have an 'acritude' that makes you react.
