I'm curious about the origin of the word Flivver. All I know about it is that it has something to do with old cars. Can anyone help me?
Google can. It gives back lots of links.
Despite my fascination with the culture of the 1920s, my main association for the word flivver is as one of the few relatively common words with a double V. The others are various forms of the slangy verb "to rev" (revved, revving) and the adjective savvy.
I've never been able to find a good word with a double J, Q, X or Y, and most of the ones I have for K (chukker, pukka) are distinctly foreign. It might be fun to see who can come up with my examples for double H or W.
Hitchhike and glowworm?
Well, that certainly didn't take long.
I would also have accepted fishhook and withhold.
