I will try and find some more words. If you look in a dictionary, you will probably find different meanings for these words; the reason being that I found these meanings in older dictionaries.
If you happen to find any interesting meanings for words, please feel free to post them.
I love you Pj.
What you have done here is not provide the old meaning or the correct meaning, but is more a matter of providing lesser known or more obscure meanings.
The definition of fag as a cigarette is a modern one... just one not common in the U.S. It comes from the older meaning of "faggot" as a burning brand or ingot of wood... the derogatory meaning for "flaming" homosexual comes from the same place.
Somebody in a mental hospital has never been the primary definition of "patient", either... that comes from the broader and more accepted meaning of it as being one who is afflicted with any disease or condition, which comes from the oldest definition as "one who suffers."
