Etymiology of the word "Bitch".

If one could find a word in the English language to be more strangely and oddly used than bitch, please let me know as soon as possible. Encompassing meanings that date back from the year 1000 A.D., it has been used to describe totally unrelated things. How did society manage to distort and skew the meaning of a word to change from referring to an animal to demeaning a person? It is not very common …

…to complain or to whine. "Why don't you just stop bitching?" The original usage of the word has become extremely that if one were to say bitch in a social atmosphere while referring to an animal, all heads in the room would turn in disbelief. Society has perverted the meaning of such an innocent word used by animal lovers into such a vulgar non accepted word. This phenomenon shows the wonders of something called time.
