A lot of people who read this blog like rare and unusual words. There are plenty of those in this recent Guardian article. They include:
eternitarian: a believer in the eternity of the soul (the OED says that anti-eternitarian is used more)
homerkin: a liquid measure
oncethmus: the bray of a donkey
suffarcinate: to truss or stuff up
weequashing: the spearing of fish or eels from a canoe by torchlight
welmish: of a pale or sickly colour
The article is about a website that has been set up to save rare words. There are lots on the site. You click on one and get a definition, plus an opportunity to 'adopt' the word. This means that you agree to try and 'save' the word in the language by dropping it into conversation at every possible opportunity, or finding other ways of spreading it around.
