Somehow, I got a hold of a 2001 desk calendar called "Forgotten English," but never got to use it. Cool discovery: it's usable again for 2007. The calendar features a new archaism every day.
Today's was "sic-sic," "Said to pigs when called to the trough by those who think little that they are speaking pure Saxon, in which sic is a pig." - The Rev. John Watson's Uncommon Words Used in Halifax, 1775.
I confess that I don't get it.
Monday's was more interesting, if a bit more disgusting: "Drink-meat" defined as "Ale boiled, thickened with oatmeal, and spiced." - Georgina Jackson's Shropshire Word-Book, 1879
