Thanks to doing some reƒearch for a story to be written in Eric Flint's 1632 univerƒe, I have diƒcoverd an excellent reƒource - Robert Cawdrey's A Table Alphabeticall of Hard Usual English Words originally publiƒhd in 1604.
The original on-line version is irritating to lookup individual words so I have produced a slightly modified version with an index that automagically goes to each word.
