Word of the day: Ruction

Holman Jenkins Jr., one of America's best columnists, weighed in today on sovereign fund investments flooding into our vulnerable economy.
He asked:

"Would we prefer they spent it patronizing the global arms industry, especially after this week's temperamental market ructions?"

Ruction. There's a word I hadn't read before. It means a disturbance or a row, and its murky origin dates to between 1815-1825. Sounds like something that might have come from Wellington at Waterloo: "Quite a ruction, eh what?"
Ruction isn't related at all to ructation, which is the act of belching wind.
Just so you know.
