There are a few words in the English lexicon that appear to draw a lot of power.
Sport is a good one. Lots of things claim to be sports, and saying something isn’t a sport is often very controversial; so much so that pretty much any type of physical competition is now considered a sport. Hell, even activities that aren’t competitive take on the moniker, like hunting or fishing.
Somehow, we have deemed “sport” to be the word with the most honor bestowed upon it, and words like “competition” are deemed to sit below it.
Art is this way as well. People clearly not making art claim to be artists all the time, like restorative painters. And people that sit well outside the traditional visual, literary, musical, or thespian arts claim all the time to be creating art.
Hell, I’ve even said that once in this space.
