This is kind of a strange project but -- let's face it -- lots of things about linguistics are strange. Tolkien used to invent whole languages more or less for fun. This is a variation of that, except it's aimed at trying to see what Modern English would be like if it were 100% Germanic rather than involving so many Romance loan-words.
It's just for fun, but we were discussing how Germanic English is (mostly, if you measure its Germanic-ness by the frequency with which Germanic-rooted words are used in speech or writing; not very, if you measure by the percentage of all English words that have Germanic roots). So here's a bit of fun.
