As a descriptive, not prescriptive, grammarian, the deeper meaning that Morissette&#x27;s song accidentally has is that there were at least three or four distinct extant definitions of &quot;irony&quot;, many people were <i>very</i> sure their definition was universal, and none of those people were right.<p>It&#x27;s sort of shocking this five-letter word turned out to have several simultaneous different non-overlapping meanings, with so many people not even realizing the differences in the way other people were using the word. There&#x27;s probably a PhD thesis in there somewhere. No joke, irony, or sarcasm.
