lollapalooza - something extraordinarily impressive, similar to a humdinger.
Attested from the 1890s but the origin is unknown; it could be a made-up word. New to me, it was in a book I’m reading. Though I’d never seen it before, the context made it clear at once what it meant, and I’ve learned a new word. Language is so productive, it’s possible to invent words that speakers will instantly grasp and start using.
Hi Richard, That's interesting there have been some neologies during the pandemic.
Yes indeed new words evolve all the time, it’s fascinating. Language has a life if its own.
