And FYI...there are lots of words and phrases that Dickens NEVER used, haven't appeared in any dictionaries, and have been used by any number of groups in the UK and America.
OTOH...there ARE books containing very old Colonial and early America, as well as Brit slang. Slang usage comes and goes; however, a certain group resurrected a many centuries old, long out of fashion word, "FLY" ( as in "fly girls" ) that wasn't ever before used in America, which I found funny, when they did so.
That’s interesting.
Have a Nice Evening.
