noun
anger caused by something that is unfair or wrong

I came across this word in The Boston’s Photograph by Nora Ephron. It is found in the sentence, “In this case, of course, the objections were all dressed up and cleverly disguised as righteous indignation about the privacy of death.” I think what this sentence is saying is that the objections were just hidden as anger about the privacy of death.
