This is an ongoing project. Many sources are being used, so definitions, dates, etc., will change and/or be added to day by day.
It includes obsolete words, rare words, obscure words, slang, colloquialisms, and dialects (American, English, and Scottish), and many others!
Please note that a number of the words are derogatory and may be offensive to some.
This is especially true of a lot of the slang entries. But that's what slang is - rude and vulgar.
So keep that in mind, and remember this is merely a record of such words.
Also note that the date, when shown, is of the earliest documented use of the word or phrase,
and not when it was first used.
Also, the dates given in sources tend to vary, so the given date should be regarded as being approximate.
