I seek to embiggen my lexicon. Does anyone know of an obscure/archaic/unusual English word-of-the-day (with authoritative (preferably OED) definition) RSS feed?
I've found the OED WotD feed, but a fleet survey shows it contains generally everyday language.
The Phrontistery is interesting, but it appears to be dead, and doesn't feature a feed of words.
Wordsmith's A Word A Day comes close, with some quite rare words. Anything else like this?
