Agita is a noun that refers to stress or aggravation.
The Italian word acido (ACH ee doe) means ‘acid’ when referring to an irritant in a person’s stomach. Its English equivalent, Agita, may refer to the same thing, but the word can be used more broadly to refer to any source of agitation or stress — medical or otherwise.
I was pretty stressed out after my first week of college. Not only did I have lots of homework, but my dorm mate was a real jerk. It’s hard to say which caused more agita in my life. Jimmy or economics 101.
