The dates in Clarence Major's book are interesting, but seem to be based on his opinion rather than documentation.
Pedant request-
If anyone has found any documented quotes of 'nappy' in print before Cassell's 1930's date, please post. Obviously the word with regard to leather, cloth, etc. is old (medieval nappig) as I noted, but I would like to find earlier usage with regard to hair - I 'remember' it from childhood, and the link to hair-straightening in the 1930's, but I think there should be earlier use. Just curious about how usage changes and develops.

I am glad that the American TV channel, BET or Black Entertainment Television, has not reached the UK public. So-called comedians and purveyors of hiphop and rap frequently use terms like 'ho, the n-word, and derogatory remarks that from whites would justify attack. Unfortunately the channel is available in Canada from cable and satellite as an extra cost site. It never should have been allowed by the CRTC (the Canadian regulatory body). In the States, the regulatory commission should act to make it clean up its programs or withdraw its license.
