Entertainment / Literature / Pejoration: A semantic change in which a word gains increasingly negative connotation. For instance, the word lewd originally referred to laymen as opposed to priests. It underwent pejoration to mean 'ignorant,' then 'base' and finally 'obscene,' which is the only surviving meaning in Modern English usage. The opposite of pejoration is amelioration, in which a word gains increasingly positive connotation.
