Imponderables revisited

Back in 2004, I mentioned that among Merriam-Webster's Words of the year was defenestration.  At the time, I wondered if there'd been an epidemic that led to it beating out many other words.

What a difference 14 years makes.

Last week, The Guardian had a review of a book about language change, Betrumped: The Surprising History of 3,000 Long-Lost, Exotic and Endangered Words (Edward Allhusen).  Apparently Allhusen lists several words that are "endangered" and, well, defenestration is on that list.
