I have a grand (and probably unattainable) dream of inventing a word that will make its way into widespread usage in the English speaking world. I’ve tried with “unvaporia”, “shufflendipity”, “unprivacy”, “undergommed”, “disagreeaphobia”, “eco-busted”, “optionitis”, and “misambulist”.
I’m now having a try with …
accusurance. noun. A word or phrase that can either be an accusation or a reassurance, depending on the tone of voice you use.
As an example, in Microsoft SharePoint 2013 and later, if you initiate an action that doesn’t complete immediately you get told that the system is “Working on it …” along with the reassuring message that “This shouldn’t take long.”
Usually it doesn’t take long, but sometimes it does. Sometimes it drags on interminably, and leads to an accusatory response by the user of “This shouldn’t take long!”
